The SWC was negatively correlated to TFRA suggesting that as trees get older, they dried the deep soil layer below the crop rooting zone and increased the soil depth able to store autumn and winter rainfall. No significant effect of either stand age or distance from tree rows was observed for SMN. It varied significantly with soil depth (R² = 0.3***) and was strongly correlated with soil nitrate content (R² = 0.97***).

The copper/ZIL molar ratio (1/4) introduced was rationally established based on molecular modeling and on the maximal copper concentration in artificially contaminated soil. Higher accumulation of copper in the shoots was detected for the uncontaminated and copper contaminated ZIL amended soils (18.9 and 23.3 mg.kg-1, respectively) together with a similar ZIL concentration of around 3% w/w detected by LC-MS analyses. These data evidenced a phytoextraction improvement of 38 and 66% compared to non-amended soils. ZIL would be mainly present under Cu(II)-ZIL4 complexes in the shoots. However depending on the soil modalities, the presence of free copper and/or free ZIL led to different chemical compositions in lignin and monomeric sugar contents. In the biorefinery context, performances of enzymatic hydrolysis of shoots were related to the presence of both ZIL and copper under free or complex forms. Ecotoxicity of the different soils indicated that the quantity of copper and ZIL remaining in the soils had no significant toxicity. ZIL amendment in a copper-contaminated soil was demonstrated as being a promising way to promote the valorization of phytoremediation plants.},

abstract = {It was largely documented that agroforestry systems promote soil biodiversity
in agroecosystems but little is known about the timing and the origin
of this improvement after the tree plantation. The aim of this study
was to measure the change in soil biodiversity abundance and repartition
during the first year of tree plantation at an experimental agroforestry
(AF) site in northern France. The experimental site is located in
Ramecourt (50° 22' N, 2° 17' E) on an 18-ha plot according to a randomized
bloc design with 3 replicates. Modalities with or without nitrogen-fixing
trees in AF treatment are compared with sole-crop (CC) and pure-forest
control (FC) plots. In November 2018, one-year-old trees and shrubs
were planted in 38 meters and 7 meters wide rows for AF and FC respectively.
Within rows, 6 species of tall trees (Quercus robur, Carpinus betulus,
Juglans regia x regia, Alnus glutinosa, Prunus avium, Robinia pseudoaccacia)
were planted 8 meters apart and were intercalated every 1 meter by
9 species of shrubs (Castanea sativa, Cornus sanguinea, Acer campestris,
Euonymus europaeus, Corylus avelana, Tilia cordata, Ligustrum vulgaris,
Salix alba, Viburnum lantana). The density of tall trees is 50 and
430 trees ha-1 for AF and FC respectively. In AF, a spring barley
was sown in February 2019 in the alley after a shallow stubble ploughing
as well as in CC plots. In FC, cover plants composed of a mixture
of melliferous and grass plant species were sown between tree rows
in April 2019. The population of earthworms, micro and macroarthropods
were measured from April to July 2019 using mustard extraction method,
Berlese and Barber traps respectively. The collected organisms were
counted, classified and identified thanks to a determination key
based on morphological criteria. The abundance and the dominancy
of each recognized families, genus or species were calculated as
well as the Shannon-index for the diversity. A total number of 833
earthworms was collected in all plots. Anecic species were dominant
(i.e. between 50% and 75% of the total number) whereas endogenic
and epigeic species were common (i.e. between 25% and 50%) and very
rare (< 5%) respectively. The abundance of earthworms was not significantly
different between AF (25.3 ind. m-2), CC (28.6 ind. m-2) and TF (19
ind. m-2). The relative abundance of the same ecological category
of worms was roughly the same for the three treatments. A total number
of 85 microarthropods was counted. Mites and collembola represented
in average 26% and 32% of the population respectively. The remaining
individuals were composed of myriapods, enchytreids and insects.
The calculated Shannon-index for the microarthropods was significantly
higher in AF (1.03) and FC (1.19) than in CC (0.26). While 7 families
of microarthropods were recorded in both AF and FC, only 3 families
were noted in CC, suggesting that at this early stage of trees development,
the population of microarthropods could benefit from more diverse
habitat and food provided by tree lines. For macroarthropods, a total
number of 11,005 individuals were collected during the 4 weeks of
sampling. Some zoological groups such as Staphylinidae, Ephistemus,
Bembidion and Araneae were only observed in AF. The abundance of
macroarthropods decreased from the beginning to the end of sampling
period in CC and FC whereas it remained stable in AF. This decrease
was probably due to the hot and dry weather conditions in July 2019.
It can be assumed that in AF, the microclimate and habitats, which
were created together by tree rows and crop canopy cover, promoted
the resilience of the installed ecosystem, allowing the maintenance
of food chain predators. The drying up of cover plants in FC or the
absence of tree rows in CC was not favourable to maintain macroarthropods
populations over time. Our study showed that the micro and macro
arthropods’ community abundance and repartition in soil react very
quickly within one year after tree plantation in AF, thanks to the
creation of favourable habitats for their development along the tree
rows. Further work is necessary to confirm these tendencies in the
following years and to identify their consequence in the ecosystem
functionning.},

may thus be subject to regulation. An international scientific workshop
was convened in Paris in September 2019firstly to assess the relevance
for public health of setting guidelines for indoor settled dust,
and secondly to discuss scientific and technical challenges related
to such guidelines. The main discussions and conclusions, with consensus
achieved, are reported herein. Discussions concernedgeneral considerations,objectives
and definitions, relevance for a health‐based guideline, units of
measure, and finally derivation of the guideline.These points should
be addressed when consideringan indoor settled dust guideline as
part of a policy to reduce exposure indoors to a given chemical or
group of chemicals. |

found that the juvenile and adult abundances, and community composition,
were significantly affected by pollution. Along the pollution gradient,
as species richness decreased. Lumbricus castaneus became more dominant.
We thus investigated the physiological response of this species to
a set of specific elements (Pb, Zn, Cu, and Cd) and studied the impacts

high quantities of Cd and Zn, but not of Cu and Pb. The population

Its late harvest in winter generates large amounts of leaf litter on the soil surface. However, little is known about the mobility and the bioavailability of metals following leaf decomposition and the consequences on the succeeding culture. Ex situ artificial aging for 1, 3, and 6 months was conducted with miscanthus leaf fragments incorporated into three agricultural soils displaying a gradient concentration in Cd (0.6, 3.1 and 7.9 mg kg−1), Pb (32.0, 194.6 and 468.6 mg kg−1), and Zn (48.4, 276.3 and 490.2 mg kg−1) to simulate the leaf litter input over 20 years of miscanthus culture. We investigated the impacts on physicochemical and biological soil parameters, CaCl2-extractable metal, and their subsequent ryegrass shoot concentrations, and hence on ryegrass health. The results showed that the amended soils possessed higher pH along with greater available phosphorous and soil organic carbon values. The respiratory activity and microbial biomass carbon in the amended soils increased mainly after 1 month of aging, and decreased afterwards. Despite the higher Pb- and Zn–CaCl2 extractability in the amended soils, the phytoavailability slightly increased only in the most contaminated soils. Moreover, leaf incorporation did not affect the ryegrass biomass, photosynthetic pigment contents, nor the antioxidative enzyme activities. Conclusively, leaf incorporation induced slight variations in soil physicochemical and biological parameters, as well as metal extractability, but not to an extent that might cause a considerable threat to the subsequent culture. Nevertheless, these results are preliminary data that require confirmation by long-term in-situ experimentations as they reflect the modelization of long-term impact of leaf decomposition on soil-plant system.},

Ex situ artificial aging for 1, 3, and 6 months was conducted with miscanthus leaf fragments incorporated into three agricultural soils displaying a gradient concentration in Cd (0.6, 3.1 and 7.9 mg kg−1), Pb (32.0, 194.6 and 468.6 mg kg−1), and Zn (48.4, 276.3 and 490.2 mg kg−1) to simulate the leaf litter input over 20 years of miscanthus culture. We investigated the impacts on physicochemical and biological soil parameters, CaCl2-extractable metal, and their subsequent ryegrass shoot concentrations, and hence on ryegrass health. The results showed that the amended soils possessed higher pH along with greater available phosphorous and soil organic carbon values. The respiratory activity and microbial biomass carbon in the amended soils increased mainly after 1 month of aging, and decreased afterwards. Despite the higher Pb- and Zn–CaCl2 extractability in the amended soils, the phytoavailability slightly increased only in the most contaminated soils. Moreover, leaf incorporation did not affect the ryegrass biomass, photosynthetic pigment contents, nor the antioxidative enzyme activities. Conclusively, leaf incorporation induced slight variations in soil physicochemical and biological parameters, as well as metal extractability, but not to an extent that might cause a considerable threat to the subsequent culture. Nevertheless, these results are preliminary data that require confirmation by long-term in-situ experimentations as they reflect the modelization of long-term impact of leaf decomposition on soil-plant system. |

the addition of a layer material to the soil surface) and their efficiency
to promote recolonization by pedofauna of isolated and degraded areas.
The experimental study was set up in the former coal mining area
of Northern France. This area is particularly disturbed and fragmented
by land-use change, urbanization, industry, intensive agriculture
and metal pollution. To examine the movements of pedofauna, four
kinds of mulches were applied: (i) Ramial Chipped Wood (RCW), (ii)
chopped Miscanthus, (iii) dead leaves and (iv) wheat straw as well
as plastic sheeting, a material often used in green spaces. A negative
control consisted in soil without mulch addition. The experimental
set-up consisted of a set of 18 bands of mulch (6 m long x 0.5 m
width x 8 cm thick, i.e. a volume of 0.04 m3 per band) installed
on three adjacent plots on a surface area which stretch on 4400 m2:
(i) plot F1, a mixed plantation, (ii) plot M consisted of three rows
of maples (both considered to be the reservoir of biodiversity) and
(iii) plot BF, an ash plantation (with lower biodiversity). Faunistic
communities of soil present within the mulches were monitoring using
pitfall traps for four months (April to July), at a rate of eight
surveys for each of the 90 traps installed, i.e. 720 samples. Different
life traits and indices of diversity were studied, more specifically
on carabid beetles. The main objective of the study was first to
check whether mulches could or not reconnect different planted plots

second aim was to find which type of mulch had the best efficiency
in the recovery of the connectivity between plots. The last questions
were which type of zoological groups could be favoured by the use
of mulches and which benefits for ecosystem functioning. The main
hypotheses of this study were: (i) Organic mulches would act as dispersal
corridors and refuge zones to the soil organisms; (ii) organic mulches
would be attractive to many organisms with various ecological needs.
This study highlighted the potential benefits of using the mulching
technique to support ecological connectivity in disturbed environment
since this method highlighted the presence of individuals with different
diets (saprophagous, predators, phytophagous and so forth), small
and large size species which do not have the same dispersal capacities
as well as species that are more dependent on forest environments
and others that depend on more open environments. The study concluded
that organic mulches are more favourable to pedofauna than soil without
mulch or plastic sheeting. With regard to organic mulches, no difference
was noted, either in terms of cumulative abundance or monthly monitoring.
However, for carabids, it should be noted that dead leaves and wheat
straw have higher specific richness than Miscanthus and RCW.},

The study focused on the attractiveness of mulches (consisting of
the addition of a layer material to the soil surface) and their efficiency
to promote recolonization by pedofauna of isolated and degraded areas.
The experimental study was set up in the former coal mining area
of Northern France. This area is particularly disturbed and fragmented
by land-use change, urbanization, industry, intensive agriculture
and metal pollution. To examine the movements of pedofauna, four
kinds of mulches were applied: (i) Ramial Chipped Wood (RCW), (ii)
chopped Miscanthus, (iii) dead leaves and (iv) wheat straw as well
as plastic sheeting, a material often used in green spaces. A negative
control consisted in soil without mulch addition. The experimental
set-up consisted of a set of 18 bands of mulch (6 m long x 0.5 m
width x 8 cm thick, i.e. a volume of 0.04 m3 per band) installed
on three adjacent plots on a surface area which stretch on 4400 m2:
(i) plot F1, a mixed plantation, (ii) plot M consisted of three rows
of maples (both considered to be the reservoir of biodiversity) and
(iii) plot BF, an ash plantation (with lower biodiversity). Faunistic
communities of soil present within the mulches were monitoring using
pitfall traps for four months (April to July), at a rate of eight
surveys for each of the 90 traps installed, i.e. 720 samples. Different
life traits and indices of diversity were studied, more specifically
on carabid beetles. The main objective of the study was first to
check whether mulches could or not reconnect different planted plots
in a peri-urban landscape highly modified by human activities. The
second aim was to find which type of mulch had the best efficiency
in the recovery of the connectivity between plots. The last questions
were which type of zoological groups could be favoured by the use
of mulches and which benefits for ecosystem functioning. The main
hypotheses of this study were: (i) Organic mulches would act as dispersal

the joint analysis based on the cross-interpretation of the spatialized
composite indices of resilience and vulnerability. A case study was
conducted to demonstrate the feasibility of this methodology, using
the municipality as a spatial unit of analysis within a region in
the north of France. To provide the most holistic description possible
of the 3817 studied municipalities, 50 variables related to the economic,
environment, policy, health, services and social dimensions were
used to develop the composite indices. The vulnerability Index has
a median value of 0.151 with an IQR of [0.126–0.180] and the Resilience
Index has a median value of 0.341 with an IQR of [0.273–0.401]. The
joint analysis was conducted to classify each municipality among
four defined typologies: 1687 municipalities (44.2%) belong to the
“To monitor” category, 1646 (43.1%) to the “Resilient” category,
329 (8.6%) to the “Have resources” category and 155 (4.1%) to the

(diclofenac, sulfamethoxazole, 17α-ethynylestradiol and triclosan)
from artificially contaminated water. Labcreated cartridges were
filled with each sorbent and all experiments were systematically
compared to activated charcoal Norit®. Results from activated charcoal,
wheat straw and acidified wheat straw were supported by the Langmuir
and Freundlich models. Wheat straw ashes were an excellent metal
extractor that exceeded the potential of well-known activated charcoal.
Acidified sorbents (wheat and ryegrass) were very effective in eliminating
the selected emerging organic contaminants displaying equipotent
or superior activity compared to activated charcoal. These results
open the way for further in natura studies by proposing new biosource
materials as new effective tools in the fight against water pollution. |

of some macrofungi occurring in the Niokolo Koba biosphere reserve.
Surveys carried out at Niokolo Koba allowed to sample, describe and
identify 14 species of fungi with fruibodies of ‘Parc National Niokolo
Koba’. These species represent 12 genera, 7 families, 4 orders all-in
the Basidiomycota. These species are: Gymnopilus sp, Hexagonia sp,
Lactocollybia sp, Lentinus sp, Lenzites cf acutus, Marasmiellus setulosipes,
Marasmius castaneovelutinus, Marasmius sp, Polyporus arcularius,
Psathyrella atroumbonata, Psathyrella tuberculata, Pulverolepiota
sp, Pterula cf brunneola, Tetrapyrgos nigripes |

have been often studied in the context of PM toxicity and generally

the underlying adaptation mechanisms that could occur following exposure
at sub-apoptotic doses of ambient PM. Here, normal human bronchial
epithelial BEAS-2B cells were acutely or repeatedly exposed to relatively
low doses (5 µg.cm−2) of FP (PM2.5-0.18) or quasi-UFP (Q-UFP; PM0.18)

functions, and dynamics. No significant cytotoxicity nor increase
of apoptotic events were reported for any exposure. Mitochondrial
membrane potential (ΔΨm) and intracellular ATP content were also
not significantly impaired. After cell exposure to sub-apoptotic
doses of FP and notably Q-UFP, oxidative phosphorylation was increased
as well as mitochondrial mass, resulting in increased production
of mitochondrial superoxide anion. Given this oxidative boost, the
NRF2-ARE signaling pathway was significantly activated. However,
mitochondrial dynamic alterations in favor of accentuated fission
process were observed, in particular after Q-UFP vs FP, and repeated
vs acute exposure. Taken together, these results supported mitochondrial
quality control and metabolism dysfunction as an early lung underlying
mechanism of toxicity, thereby leading to accumulation of defective
mitochondria and enhanced endogenous ROS generation. Therefore, these
features might play a key role in maintaining PM-induced oxidative
stress and inflammation within lung cells, which could dramatically
contribute to the exacerbation of inflammatory chronic lung diseases.
The prospective findings of this work could also offer new insights
into the physiopathology of lung toxicity, arguably initiate and/or
exacerbate by acutely and rather repeated exposure to ambient FP

the term “environment” refers to both the ecological and social surroundings;

And how should environmental contamination and exposure be evaluated?
The objective was to perform a systematic review of the literature
on Crohn’s disease and environmental contamination. We searched the

We considered all field studies previous to April 2019 conducted
on human health indicators, and evaluating exposure to all type of
physical, biological and chemical contamination of the environment.

number of field studies (n ¼ 16 of 39 publications, most of which
were conducted by pioneering medical scientists), methodological
differences, and the small number of contaminants evaluated. This
make it impossible to conduct a coherent and efficient meta-analysis.

five recommendations on improving future research: (i) follow up
the currently identified leads - especially metals and endocrine
disruptors; (ii) explore soil contamination; (iii) gain a better

An improved procedure for the synthesis of meloxicam drug (methyl
4-hydroxy-2-methyl-2H-1,2-benzothiazol-2-amine-3-carboxylate 1,1-dioxide)
was described in one-step using mainly impregnated montmorillonite
K10 (MK10) with ZnCl2 as a heterogeneous catalyst. This innovative
method was compared to the last described procedure employed in the
manufacture of this anti-inflammatory drug by means of some metrics
used in a first step of the evaluation process of the environmental
impact of a chemical transformation. Apart from the yield, which
was 90%, atom economy, waste, environmental factor, reaction mass
efficiency and stoichiometric factor were calculated as 91.6%, 8.4%,
0, 8.1% and 1%, respectively. Interpretation of these metrics was
given and highlighted the fact that the strategy used in the current
study may be considered as an environmental-friendly and sustainable
method that fits well in the green chemistry concepts. |

kinetics of the carbon steel components of some disposal cells. In

the oxidation of pyrite in contact with clays and carbonates at 100

thermodynamic modelling expects that hematite is the most stable
phase in a pure pyrite heated system (low pH), experiments show the
formation of native sulfur as an intermediate product of the reaction.
In the presence of calcite, the pH is neutralized and drives the
lower reactivity of pyrite in the absence of native sulfur. The addition
of clay phases or other detrital silicates from the claystone had
no impact on pyrite oxidation rate. The discrepancies between experiments
and thermodynamic modelling are explained by kinetic effects. Two
laws were deduced at 100 degrees C. The first concerns a pure pyrite system, with the following law: rPy= 10-4.8 center dot PO20.5 center dot t-0.5. The second concerns a pyrite/carbonates system: rPy+Ca=

to the partial pressure of O-2 (in bar) and t is time in seconds.

In the context of global warming, an increase in soil drought is suspected
by the IPCC predictions and litter breakdown activity could be affected.
An experiment was conducted using microcosms (controlled conditions)
and woodlice which are recognized as shredders of litter and bioindicators
of global warming. The impact of relative air humidity (90 and 50%
RH) on litter breakdown by woodlice was studied through the monitoring
of one behavioral (distribution of individuals on microcosms), one
morphological (Absolute Growth Rate) and four physiological traits
(Survival rate, Relative Consumption Rate, Relative Growth Rate,
Feeding rate). Four species of isopods known to have different microclimatic
sensitivities (Armadillidium vulgare, Porcellio scaber, Oniscus asellus,
Philoscia muscorum) were used simultaneously. Sensitivities of males
and females have also been tested. Main results showed that the seven

induced in Altigo, the most resistant cultivar, seem to be more specifically
mediated by the phenylpropanoid pathway in non-inoculated as well
as inoculated plants, since PAL and CHS were most specifically upregulated
in this cultivar. In Premio, the moderate resistant cultivar, NECTAR

The first stage is characterized by relatively low Th and low salinities (155-205° C and 0.5-3.2 wt% eq. NaCl). The second stage, which was characterized both by the formation of mode-I joints and by mode-I reactivation of preexisting veins, shows higher Th and salinities (215-270°C and 2.2-5.7 wt% eq. NaCl). Waters recorded in the second stage are interpreted to have interacted with underlying Triassic evaporites and flowed along major thrusts before vein precipitation, which are locally in thermal disequilibrium with host-rocks. We suggest the transition from a
rather closed hydrological system during the first stage of vein formation, interpreted to have occurred during Eaux-chaudes thrusting (upper Lutetian-Bartonian), to a more open hydrological system during the second stage, which likely occurred during Gavarnie thrusting (Priabonian-early Rupelian).

sequence, similar to 550-650 degrees C, 3.5-4.0 kbar) was developed

second-order S1 band reveals that carbonaceous material (CM) was
transformed to highly "ordered" locally tridimensional graphitic
carbon at Ballachulish by regional metamorphism prior to contact
metamorphism, whereas CM was still a disordered turbostratic (bidimensional)
material before contact metamorphism in the case of Nelson. Pretexturation
of CM likely induced sluggish recrystallization of CM and delayed
graphitization in the Ballachulish aureole. Temperatures of recrystallization

the retarded crystallization noted above results in increasing underestimates
of temperatures compared to the metapelitic phase equilibria (up
to similar to 75 degrees C too low within 200 m of the igneous contact).

The degree of recrystallization of carbonaceous material (CM), as
monitored by Raman microspectroscopy, was examined as a function
of metamorphic grade in two well-studied contact aureoles containing
carbonaceous pelites: the Nelson aureole, British Columbia and the
Ballachulish aureole, Scotland. Here, we use (a) the R2 ratio extracted
from the Raman spectrum of CM as a proxy for the degree of graphitization
(0.0 in perfect graphite then increasing with structural defects)
and (b) the second-order S1 band (similar to 2,700 cm(-1)) as a marker
for the tridimensional ordering of CM. The Nelson aureole (garnet-staurolite-andalusite-sillimanite-K-feldspar

contrary, the north of the Glarus area shows an apparent break in
the exhumation, with P estimates from chlorite crystal rims (similar

0.8 kbar). Even if the absolute pressure values are fraught with
large uncertainty, their contrasting core/rim pattern is not model
dependent. We try to correlate these new thermobarometric results

do not reveal what happens on the field, by overestimating plant
metal uptake capacity but also by modifying plant response to metal

quantifier les transferts hydro-sédimentaires sur deux années hydrologiques

studies of columns packed with core-shell and sub-core-shell particles
demonstrated improved efficiency separation, time reduction, solvent

environmental pollutants are being analysed under green conditions.
Objective: This paper presents theoretical aspects and a review of
the main features of core-shell technology focusing essentially on
environmental applications.
Method: The main advantages of core-shell columns may be summarized
as follows: i) reduction of the eddy dispersion A term; ii) homogeneity
of the particle size distribution reducing the velocity bias; (iii)
superior mass transfer kinetics; iv) better performance of the separation
(faster and greater).
Results: Systematic comparisons with fully porous particles undeniably
highlighted the benefits of core-shell technology in the separation
of a great number of pollutants and “micropollutants” of different
molecular weights which surround us and have an impact on the ecosystem.
Conclusion: Core-shell particles are emerging as green substrates
for the analysis of chemical species problematic for environment.
The environmental gain in terms of limitation of analysis time and
solvent consumption has been demonstrated. The current manuscript

abstract = {This study aims at understanding the origin and nature of syn-orogenic fluid flow in the jaca basin from the south pyrenean fold and thrust-belt, recorded in calcite and quartz veins of the sierras interiores (spain) and the turbiditic basin, which cover upper cretaceous to late eocene syntectonic deposits. the fracture network consists of a classical pattern of transverse and longitudinal fractures with respect to folds, that we propose to be related to layer parallel shortening (lps) and folding respectively. veins filled equally about the third of fractures in the carbonate shelf and turbidites. carbon and oxygen isotopes of calcite veins mostly indicate precipitation from isotopically buffered water, consistent with high water-rock interaction. in the sierras interiores, petrographical observations and fluid inclusion microthermometry are consistent with two distinct stages of precipitation. the first stage is characterized by relatively low th and low salinities (155-205◦ c and 0.5-3.2 wt% eq. nacl respectively). the second stage, characterized both by the formation of mode-i joints and by mode-i reactivation of preexisting veins, shows higher th and salinities (215-270◦c and 2.2-5.7 wt% eq. nacl respectively). low salinities recorded during the first stage suggest dilution of marine water by fresh water expelled by the smectite to illite transformation at t < 200◦c. waters recorded in the second stage are interpreted to have interacted with underlying triassic evaporites and flowed along major thrusts before vein precipitation, which are locally in thermal disequilibrium with hostrocks. we suggest the transition from a rather closed hydrological system during the first stage of vein formation, interpreted to have occurred during eaux-chaudes thrusting (upper lutetian-bartonian), to a more open hydrological system during the second stage, which likely occurred during gavarnie thrusting (priabonian-early rupelian). this evolution exhibits many similarities with other fold-and-thrust belts, except in the limited involvement of meteoric water. finally, we also document the migration in space and time of hydrothermal pulses along the south pyrenean foreland basin, related to the westward propagation of major thrusts during the pyrenean orogeny},

This study aims at understanding the origin and nature of syn-orogenic fluid flow in the jaca basin from the south pyrenean fold and thrust-belt, recorded in calcite and quartz veins of the sierras interiores (spain) and the turbiditic basin, which cover upper cretaceous to late eocene syntectonic deposits. the fracture network consists of a classical pattern of transverse and longitudinal fractures with respect to folds, that we propose to be related to layer parallel shortening (lps) and folding respectively. veins filled equally about the third of fractures in the carbonate shelf and turbidites. carbon and oxygen isotopes of calcite veins mostly indicate precipitation from isotopically buffered water, consistent with high water-rock interaction. in the sierras interiores, petrographical observations and fluid inclusion microthermometry are consistent with two distinct stages of precipitation. the first stage is characterized by relatively low th and low salinities (155-205◦ c and 0.5-3.2 wt% eq. nacl respectively). the second stage, characterized both by the formation of mode-i joints and by mode-i reactivation of preexisting veins, shows higher th and salinities (215-270◦c and 2.2-5.7 wt% eq. nacl respectively). low salinities recorded during the first stage suggest dilution of marine water by fresh water expelled by the smectite to illite transformation at t < 200◦c. waters recorded in the second stage are interpreted to have interacted with underlying triassic evaporites and flowed along major thrusts before vein precipitation, which are locally in thermal disequilibrium with hostrocks. we suggest the transition from a rather closed hydrological system during the first stage of vein formation, interpreted to have occurred during eaux-chaudes thrusting (upper lutetian-bartonian), to a more open hydrological system during the second stage, which likely occurred during gavarnie thrusting (priabonian-early rupelian). this evolution exhibits many similarities with other fold-and-thrust belts, except in the limited involvement of meteoric water. finally, we also document the migration in space and time of hydrothermal pulses along the south pyrenean foreland basin, related to the westward propagation of major thrusts during the pyrenean orogeny |

Summary
To study the impact of the constant and inevitable inhalation of moulds, it is necessary to sample, identify and count the spores.
Background
Environmental sampling methods can be separated into three categories: surface sampling is easy to perform but non quantitative, air sampling is easy to calibrate but provides time limited information, and dust sampling which is more representative of long term exposure to moulds. The sampling strategy depends on the objectives (evaluation of the risk of exposure for individuals; quantification of the household contamination; evaluation of the efficacy of remediation). The mould colonies obtained in culture are identified using microscopy, Maldi-TOF, and/or DNA sequencing.
Viewpoints
Electrostatic dust collectors are an alternative to older methods for identifying and quantifying household mould spores. They are easy to use and relatively cheap. Colony counting should be progressively replaced by quantitative real-time PCR, which is already validated, while waiting for more standardised high throughput sequencing methods for assessment of mould contamination without technical bias.
Conclusion
Despite some technical recommendations for obtaining reliable and comparable results, the huge diversity of environmental moulds, the variable quantity of spores inhaled and the association with other allergens (mites, plants) make the evaluation of their impact on human health difficult. Hence there is a need for reliable and generally applicable quantitative methods.},

De nos jours, la contamination des sols par les polluants organiques et inorganiques est une problématique majeure. des techniques douces de remédiation, reposant sur l’utilisation de plantes et de microorganismes, associés à des amendements ou non, sont étudiées pour gérer ces sols. parmi les différents amendements, le biochar est présenté dans la littérature comme pouvant répondre à ces attentes. ce travail se propose d’évaluer l’impact des paramètres de pyrolyse sur les caractéristiques de huit biochars élaborés à partir de miscanthus x giganteus, cultivé sur un sol contaminé en métaux, et de sélectionner le(s) biochar(s) susceptible(s) d’être le(s) plus performant(s) en termes de remédiation de sols contaminés en métaux (cd, pb, zn) et/ou hap. il a été mis en évidence une forte influence de la température de pyrolyse sur les caractéristiques des biochars. de plus, les biochars ont présenté de fortes capacités de sorption des trois métaux et des hap en solution, notamment pour les biochars produits à 600°c. des expérimentations réalisées avec un sol artificiel et une terre agricole contaminés artificiellement ont mis en évidence la capacité de certains biochars à diminuer la disponibilité environnementale, la biodisponibilité et la bioaccessibilité orale des métaux et des hap. sur la base des résultats obtenus, un biochar a été sélectionné comme répondant le mieux aux attentes en termes de gestion de sols multicontaminés. compte tenu des modifications structurelles du biochar dans les sols, il conviendrait de valider ces résultats sur le long terme, en condition in situ, tout en s’assurant de l’innocuité du biochar étudié et en intégrant les aspects socioéconomiques. |

Lumbricid earthworms are often exposed to simultaneous action of various environmental stressors like soil contamination, temperature fluctuation or predators' attacks, which may induce extrusion of coelomocytecontaining coelomic fluid or loss of tail segments. if the injuries are not lethal, renewal of the immune-competent cells and soluble components of coelomic fluid and/or the regeneration of tail segments occurs. the aim of our investigations was to test the hypothesis that exposure of adult earthworms eisenia andrei to cadmium-polluted soil at room temperature (rt) and/or low temperature (6 °c) have adverse effects on restoration of experimentally depleted coelomocytes or on regeneration of amputated posterior segments. intact control earthworms and their experimental counterparts subjected to electrostimulation-induced coelomocyte depletion or surgical amputation of posterior segments were maintained either in control soil or in soil spiked with cadmium chloride (500 mg/kg air-dried soil) at rt or 6 °c. four weeks after the beginning of experiments, cadmium accumulation in earthworm bodies was significantly lower at 6 °c than at room temperature. the numbers of restored cells and fluorophore contents were hardly affected by temperature or cadmium. however, cocoon production was reduced by cadmium and completely abolished at 6 °c and regeneration of amputated posterior segments was inhibited in cold but was enhanced by cadmium exposure at rt. independently on the temperature, the 4-week cadmium exposure of adult earthworms was connected with significantly upregulated expression of cd-metallothionein (but not of catalase, lysenin and phytochelatin) in coelomocytes |

The dissolved compound concentration gradient in the sediment in the vertical direction was measured at the outlet of a storm water pond by using polyethylene strips as passive samplers. Simultaneously, the dissipation of a set of tracer compounds preloaded in the passive samplers was measured to estimate the effective diffusion coefficients of the pollutants in the sediment. Both measurements were used to evaluate the diffusive flux of the compounds according to Fick's first law. The diffusive fluxes of the 3 studied compounds have been estimated with a centimetre-scale resolution in the upper 44 cm of the sediment. According to the higher compound diffusion coefficient and the steeper concentration gradient in the surficial sediment layer, the results show that the net flux of compounds near the sediment interface (1 cm depth) is on average 500 times higher than in the deep sediment, with average fluxes at 1 cm depth on the order of 5, 0.1 and 0.1 ng/m2/y for fluorene, fluoranthene and pyrene, respectively.},

The diffusive fluxes of the 3 studied compounds have been estimated with a centimetre-scale resolution in the upper 44 cm of the sediment. According to the higher compound diffusion coefficient and the steeper concentration gradient in the surficial sediment layer, the results show that the net flux of compounds near the sediment interface (1 cm depth) is on average 500 times higher than in the deep sediment, with average fluxes at 1 cm depth on the order of 5, 0.1 and 0.1 ng/m2/y for fluorene, fluoranthene and pyrene, respectively. |

abstract = {It is now established that risk assessment and management strategies for contaminated environments should consider biological responses, including environmental genotoxicity. the characterization of terrestrial ecosystem contamination by genotoxicants requires to assess their environmental and toxicological bioavailabilities and to identify adverse effects at the individual and population levels. genotoxicity in field species is assessed by means of markers focusing on genomic alterations and dna damage, like dna adducts (less used lately), micronuclei and nuclear abnormalities and dna breaks. epigenetic changes are not investigated so far. the comet assay (with the use or not of endonucleases) has nowadays largely supplanted pre-existing techniques for dna damage assessment. all these tools/techniques have first been used, optimized and validated with aquatic species. their application to soil species has emerged in a second step and is now widespread. we will present briefly some results illustrating interests of the comet assay to approach the “genotoxic bioavailability” of terrestrial contaminants and their effects on earthworms. in both aquatic and terrestrial environments, genotoxicity is generally measured in somatic cells. in some cases, it could be related to mutations, embryo mortality or reproduction impairment. however, there is a need for works linking (1) genotoxicity in individuals and (2) population dynamics and genetics. studies with gametes, early life stages and juveniles, and in environmentally relevant conditions should be conducted to reach such objectives.},

It is now established that risk assessment and management strategies for contaminated environments should consider biological responses, including environmental genotoxicity. the characterization of terrestrial ecosystem contamination by genotoxicants requires to assess their environmental and toxicological bioavailabilities and to identify adverse effects at the individual and population levels. genotoxicity in field species is assessed by means of markers focusing on genomic alterations and dna damage, like dna adducts (less used lately), micronuclei and nuclear abnormalities and dna breaks. epigenetic changes are not investigated so far. the comet assay (with the use or not of endonucleases) has nowadays largely supplanted pre-existing techniques for dna damage assessment. all these tools/techniques have first been used, optimized and validated with aquatic species. their application to soil species has emerged in a second step and is now widespread. we will present briefly some results illustrating interests of the comet assay to approach the “genotoxic bioavailability” of terrestrial contaminants and their effects on earthworms. in both aquatic and terrestrial environments, genotoxicity is generally measured in somatic cells. in some cases, it could be related to mutations, embryo mortality or reproduction impairment. however, there is a need for works linking (1) genotoxicity in individuals and (2) population dynamics and genetics. studies with gametes, early life stages and juveniles, and in environmentally relevant conditions should be conducted to reach such objectives. |

abstract = {Accumulation of heavy metals in soils poses a potential risk to plant
production, which is related to availability of the metals in soil.
The phytoavailability of metals is usually evaluated using extracting
solutions such as salts, acids or chelates. The purpose of this study
was to identify the most significant soil parameters that can be
used to predict the concentrations of acetic and citric acid-extractable
cadmium (Cd), lead (Pb) and zinc (Zn) in contaminated woody habitat
topsoils. Multiple linear regression models were established using
two analysis strategies and three sets of variables based on a dataset
of 260 soil samples. The performance of these models was evaluated
using statistical parameters. Cation exchange capacity, CaCO3, organic
matter, assimilated P, free Al oxide, sand and the total metal concentrations
appeared to be the main soil parameters governing the solubility
of Cd, Pb and Zn in acetic and citric acid solutions. The results
strongly suggest that the metal solubility in extracting solutions
is extractable concentration-dependent since models were overall
improved by incorporating a change point. This change point detection
method was a powerful tool for predicting extractable Cd, Pb and
Zn. Suitable predictions of extractable Cd, Pb and Zn concentrations
were obtained, with correlation coefficient (adjusted r) ranging
from 0.80 to 0.99, given the high complexity of the woody habitat
soils studied. Therefore, the predictive models can constitute a
decision-making support tool for managing phytoremediation of contaminated
soils, making recommendations to control the potential bioavailability
of metals. The relationships between acetic and/or citric acid-extractable
concentrations and the concentrations of metals into the aboveground
parts of plants need to be predicted, in order to make their temporal
monitoring easier.},

production, which is related to availability of the metals in soil.
The phytoavailability of metals is usually evaluated using extracting
solutions such as salts, acids or chelates. The purpose of this study
was to identify the most significant soil parameters that can be
used to predict the concentrations of acetic and citric acid-extractable
cadmium (Cd), lead (Pb) and zinc (Zn) in contaminated woody habitat
topsoils. Multiple linear regression models were established using
two analysis strategies and three sets of variables based on a dataset
of 260 soil samples. The performance of these models was evaluated
using statistical parameters. Cation exchange capacity, CaCO3, organic
matter, assimilated P, free Al oxide, sand and the total metal concentrations
appeared to be the main soil parameters governing the solubility
of Cd, Pb and Zn in acetic and citric acid solutions. The results
strongly suggest that the metal solubility in extracting solutions
is extractable concentration-dependent since models were overall
improved by incorporating a change point. This change point detection
method was a powerful tool for predicting extractable Cd, Pb and
Zn. Suitable predictions of extractable Cd, Pb and Zn concentrations
were obtained, with correlation coefficient (adjusted r) ranging
from 0.80 to 0.99, given the high complexity of the woody habitat
soils studied. Therefore, the predictive models can constitute a
decision-making support tool for managing phytoremediation of contaminated
soils, making recommendations to control the potential bioavailability
of metals. The relationships between acetic and/or citric acid-extractable
concentrations and the concentrations of metals into the aboveground
parts of plants need to be predicted, in order to make their temporal
monitoring easier. |

abstract = {In ten years, the application of the comet assay has been established as one of the most interesting techniques in eco-genotoxicology. it is a rapid, sensitive and relatively inexpensive assay for measuring dna damages and repairs in individual cells. however, its use in plant studies was rather limited compared to animal studies because of (i) the difficulty to isolate intact nuclei compared to animal systems, (ii) the low throughput of current nucleus extraction, and (iii) the lack of a high throughput comet assay scoring method. in the frame of the french-norwegian project compack (2014-2017), we first developed a new nucleus extraction technique compatible with the medium-throughput comet assay (12-gel system). this new extraction method appeared to be faster, more reliable and more efficient than the so far used methods. however, the mechanical nuclei extraction generates nonuniform backgrounds with several debris that could potentially induce bias in image analysis with automated scoring systems. thus, we have optimized our nuclei extraction to reduce the presence of debris and increase background quality. meanwhile, we have worked on the automation of the scoring method which represents a technological breakthrough in plant comet assay. we have adapted the automated scoring system pathfinder™, developed by imstar, which was initially set up for human/animal cells, to score plant nuclei. our promising results open up the perspective of an automated high-throughput scoring of plant nuclei.},

In ten years, the application of the comet assay has been established as one of the most interesting techniques in eco-genotoxicology. it is a rapid, sensitive and relatively inexpensive assay for measuring dna damages and repairs in individual cells. however, its use in plant studies was rather limited compared to animal studies because of (i) the difficulty to isolate intact nuclei compared to animal systems, (ii) the low throughput of current nucleus extraction, and (iii) the lack of a high throughput comet assay scoring method. in the frame of the french-norwegian project compack (2014-2017), we first developed a new nucleus extraction technique compatible with the medium-throughput comet assay (12-gel system). this new extraction method appeared to be faster, more reliable and more efficient than the so far used methods. however, the mechanical nuclei extraction generates nonuniform backgrounds with several debris that could potentially induce bias in image analysis with automated scoring systems. thus, we have optimized our nuclei extraction to reduce the presence of debris and increase background quality. meanwhile, we have worked on the automation of the scoring method which represents a technological breakthrough in plant comet assay. we have adapted the automated scoring system pathfinder™, developed by imstar, which was initially set up for human/animal cells, to score plant nuclei. our promising results open up the perspective of an automated high-throughput scoring of plant nuclei. |

abstract = {Three configurations of single-phase-polymer passive samplers made of polyoxymethylene (pom), silicone rubber (sr) and polyethylene (pe) were simultaneously calibrated in laboratory experiments by determining their partitioning coefficients and the pom diffusion coefficients and by validating a kinetic accumulation model. in addition, the performance of each device was evaluated under field conditions. with the support of the developed model, the device properties were discussed with regard to material selection and polymer thickness. the results show that a sampler's properties, such as its concentration-averaging period and ability to sample a large amount of pahs, are widely affected by material selection. sampler thickness also allows modulation of the properties of the device but with a much lower magnitude. the selection of the appropriate polymer and/or thickness allows samplers to be adapted either for quick equilibration or for the kinetic accumulation regime and promotes either membrane or water boundary layer control of the kinetic accumulation. additionally, membrane-controlled or equilibrated compounds are quantified with greater accuracy because they are not corrected by the performance reference compounds (prc) approach. however, the averaged concentrations cannot be assessed when compounds reach equilibrium in the sampler, whereas membrane-controlled devices remaining in the kinetic accumulation regime provide averaged concentrations without requiring prc correction; detection limits are then increased because of the higher mass transfer resistance of the membrane.},

Three configurations of single-phase-polymer passive samplers made of polyoxymethylene (pom), silicone rubber (sr) and polyethylene (pe) were simultaneously calibrated in laboratory experiments by determining their partitioning coefficients and the pom diffusion coefficients and by validating a kinetic accumulation model. in addition, the performance of each device was evaluated under field conditions. with the support of the developed model, the device properties were discussed with regard to material selection and polymer thickness. the results show that a sampler's properties, such as its concentration-averaging period and ability to sample a large amount of pahs, are widely affected by material selection. sampler thickness also allows modulation of the properties of the device but with a much lower magnitude. the selection of the appropriate polymer and/or thickness allows samplers to be adapted either for quick equilibration or for the kinetic accumulation regime and promotes either membrane or water boundary layer control of the kinetic accumulation. additionally, membrane-controlled or equilibrated compounds are quantified with greater accuracy because they are not corrected by the performance reference compounds (prc) approach. however, the averaged concentrations cannot be assessed when compounds reach equilibrium in the sampler, whereas membrane-controlled devices remaining in the kinetic accumulation regime provide averaged concentrations without requiring prc correction; detection limits are then increased because of the higher mass transfer resistance of the membrane. |

abstract = {Several naturally occurring biological materials, including bones
and teeth, pathological calcifications, microbial mineral deposits
formed in marine phosphogenesis areas, as well as bio-inspired cements
used for bone and tooth repair are composed of Ca-phosphates. These
materials are usually identified and characterized using bulk-scale
analytical tools such as X-ray diffraction, Fourier transform infrared
spectroscopy or nuclear magnetic resonance. However, there is a need
for imaging techniques that provide information on the spatial distribution
and chemical composition of the Ca-phosphate phases at the micrometer-
and nanometer scales. Such analyses provide insightful indications
on how the materials may have formed, e.g. through transient precursor
phases that eventually remain spatially separated from the mature
phase. Here, we present scanning transmission X-ray microscopy (STXM)
analyses of Ca-phosphate reference compounds, showing the feasibility
of fingerprinting Ca-phosphate-based materials. We calibrate methods

Several naturally occurring biological materials, including bones
and teeth, pathological calcifications, microbial mineral deposits
formed in marine phosphogenesis areas, as well as bio-inspired cements
used for bone and tooth repair are composed of Ca-phosphates. These
materials are usually identified and characterized using bulk-scale
analytical tools such as X-ray diffraction, Fourier transform infrared
spectroscopy or nuclear magnetic resonance. However, there is a need
for imaging techniques that provide information on the spatial distribution
and chemical composition of the Ca-phosphate phases at the micrometer-
and nanometer scales. Such analyses provide insightful indications
on how the materials may have formed, e.g. through transient precursor
phases that eventually remain spatially separated from the mature
phase. Here, we present scanning transmission X-ray microscopy (STXM)
analyses of Ca-phosphate reference compounds, showing the feasibility
of fingerprinting Ca-phosphate-based materials. We calibrate methods
to determine important parameters of Ca-phosphate phases, such as
their Ca/P ratio and carbonate content at the ∼25 nm scale, using
X-ray absorption near-edge spectra at the C K-, Ca L2,3- and P L2,3-edges.

abstract = {Emissions from primary lead smelters have been recognized as one of the mainly factor which has contributed to the contamination of soils by metals. less attention has been paid to volatile metalloids such as arsenic (as) which accompanies lead (pb) smelting activities. one of the objectives of this study was to determine the as concentrations in various extracting solutions using a collection of urban soils located no far away from two former pb and zinc plants in the north of france. the procedure for the determination of as, asiii, and asv with hydride vapor generator atomic absorption spectrometry was described in details. pseudo-total concentrations of as in the studied soils ranged from 5.3 to 65.9 mg kg-1. good correlations were found between as and lead, zinc, and cadmium concentrations in soils. these depended on the soil uses and the soil distance from the source of contamination. because the form of as may pose a health risk to human population, its speciation was determined in each urban top soils. very good correlations were found between asiii and asv versus as concentrations in soils studied, but the results did no permit to establish a relation between the location of soils and their uses. in contrast, it was shown that the highest mobility factor and lowest partitioning index values were related to the location. the mobilty of as depended on the assimilated phosphorus (p), carbonate contents, and ph. the percentages of the water-extractable as concentrations ranged from 0.3 to 3.0 % of the as concentrations in soils. very good positive correlations between water-extractable asiii and asv versus water-extractable as concentrations were obtained. it was shown that the water-extractable asiii concentrations depended on the soil uses. the results revealed that soils for which the as was the most mobile presented the highest water-extractable as concentrations. principal component analysis indicated that mechanisms related to the release of as depended on the physico-chemical parameters of the soils, particularly on the assimilated p, organic matter, and/or iron oxides/hydroxides contents. finally, the glasshouse experiments using ryegrass as plant model and three soils with similar physico-chemical parameters with regard to the pca analysis showed that the water extracting solution could be a good indicator to evaluate the as phytoavailability},

Emissions from primary lead smelters have been recognized as one of the mainly factor which has contributed to the contamination of soils by metals. less attention has been paid to volatile metalloids such as arsenic (as) which accompanies lead (pb) smelting activities. one of the objectives of this study was to determine the as concentrations in various extracting solutions using a collection of urban soils located no far away from two former pb and zinc plants in the north of france. the procedure for the determination of as, asiii, and asv with hydride vapor generator atomic absorption spectrometry was described in details. pseudo-total concentrations of as in the studied soils ranged from 5.3 to 65.9 mg kg-1. good correlations were found between as and lead, zinc, and cadmium concentrations in soils. these depended on the soil uses and the soil distance from the source of contamination. because the form of as may pose a health risk to human population, its speciation was determined in each urban top soils. very good correlations were found between asiii and asv versus as concentrations in soils studied, but the results did no permit to establish a relation between the location of soils and their uses. in contrast, it was shown that the highest mobility factor and lowest partitioning index values were related to the location. the mobilty of as depended on the assimilated phosphorus (p), carbonate contents, and ph. the percentages of the water-extractable as concentrations ranged from 0.3 to 3.0 % of the as concentrations in soils. very good positive correlations between water-extractable asiii and asv versus water-extractable as concentrations were obtained. it was shown that the water-extractable asiii concentrations depended on the soil uses. the results revealed that soils for which the as was the most mobile presented the highest water-extractable as concentrations. principal component analysis indicated that mechanisms related to the release of as depended on the physico-chemical parameters of the soils, particularly on the assimilated p, organic matter, and/or iron oxides/hydroxides contents. finally, the glasshouse experiments using ryegrass as plant model and three soils with similar physico-chemical parameters with regard to the pca analysis showed that the water extracting solution could be a good indicator to evaluate the as phytoavailability |

mm/yr) is superimposed on a north–south age gradient (2.7 Ma to present),

and rock age on the chemical weathering of volcanic terrains. Taking
advantage of this configuration, we present the first temporal survey
(2007–2013) of the geochemical composition of the dissolved load
of rain and river waters in Guadeloupe.
Our data demonstrate that the chemical composition of river water
is influenced by rainfall abundance, hydrothermal alteration (from
active or fossilized volcanic systems) and interactions between water
and minerals during chemical weathering processes. The contribution
of rain to the overall chemical balance is especially significant
in the older northern part of the island, where the ferralitic soils
are base-cation-depleted. Between 15% and 65% of the Ca or Mg riverine
budgets comes from atmospheric deposits, highlighting the major role
of rainfall in the geochemical budgets of small tropical and mountainous
watersheds. The river water dataset indicates that different chemical
weathering processes dominate the budget depending on the age of
the local bedrock. In the younger, southern part of the island, a
pool of easily-weatherable andesitic minerals from the bedrock dominates.
The contribution from this pool decreases significantly (to 5–15
wt.% of the bulk soil) towards the older terrains in the north. The
northern rivers are characterized by low Ca/Mg ratios (0.5–1.0),
intermediate between those of fresh rocks (1.7–3.3) and soil (0.1).
Weathering in the northern part of the island is therefore dominated
by the dissolution of depleted secondary minerals into soils. The
Ca/Mg ratio of the river water increases from north to south, eventually
reaching values similar to those of the bedrocks, arguing for congruent
dissolution of the youngest volcanic rocks.
The magnesium isotopic composition of river water (δ26Mg) reflects
inputs from both rain and weathering processes. In southern and central
rivers, the Mg isotopic value of waters after correction for rain
inputs (δ26Mgwea) is systematically depleted in heavy isotopes (mean
value of −0.34‰) relative to that of the bedrock (−0.24‰ to −0.15‰).
In the north, the δ26Mgwea of the river water (−0.09‰) is heavier
than that of the andesitic bedrock, possibly reflecting the dissolution
of 26Mg-rich secondary minerals (ferralitic soil measured around
+0.13‰). The robustness of δ26Mg and Ca/Mg as proxies of the degree
of soil weathering should be investigated further via more detailed
sampling campaigns in the future.
By combining high-frequency monitoring of river discharge with measurements
of concentration–discharge relationships for a wide range of chemical
elements, we estimate the mean annual chemical weathering fluxes
for three rivers that belong to the OBSERA critical zone observatory.
Fluxes vary from 51.7 to 91.8 t/km2/yr north to south along the bedrock
age gradient, and are among the highest recorded in volcanic tropical
regions. Flash floods can explain 21–31% of the annual chemical weathering
fluxes. The results highlight the importance of monitoring rivers

and in planta of several essential oils on several biological models.
Here, the aim of the study is to test the efficacy of 7 essential
oils on spores of Venturia inaequalis, the fungus that causes apple
scab (70% yield loss). Two strains were used: a resistant strain
to fungicides (triazoles) compared to a sensitive strain. A range
of concentrations of seven essential oils and two references fungicides
(metconazole and copper sulfate (CuSO4)) are tested on two strains.
The experiments were performed in a liquid medium in microplates
and are carried out at least three times in independent way. The
fungicidal effectiveness is modeled by the calculation of the IC50.
The IC50 values of the tested products is compared by an F-test within
a nonlinear regression approach. Among the 7 essential oils, the
results show that some are significaly more effective than others
on the two strains. The results also show that the resistant strain
to metconazole is much more sensitive to copper than the sensitive
strain. Similarly, the resistant strain seems sometimes to be more
sensitive to essential oils than the sensitive strain. If metconazole
remains the most effective fungicide molecule on the 2 strains, essential
oils are as or more effective than copper on the sensitive strain.
These results suggest that the behavior in the laboratory of the
R and S strains triazoles is different not only to copper but also
