The biomass of this nonfood crop was from a highly contaminated agricultural soil by potentially toxic metals (Cd, Pb and Zn) with the aim of maintaining the agricultural vocation of these soils. In this perspective and in view of the metal concentration (Cd, Pb, Zn, macro- and micro-nutrients), the biomass of ryegrass was considered as a bio ’ore’ resource and was used as the starting material for the preparation of contemporary biosourced catalysts. The heterogeneous catalyst from the current work was successfully used in the synthesis of Moclobemide, used to treat anxiety and major depressive episodes. Through this original approach, Moclobemide was synthesized in one step, in 80% yield under solvent-free conditions. |

Alternative urban spaces should be designed considering new requirements in terms of urban microclimate and thermal comfort. Pervious pavements such as green parking lots can contribute to this goal through solar evaporative cooling. However, the cooling benefits of such systems remain under debate during dry and warm periods. The aim of this study was to compare experimentally the thermal behavior of different parking lot types (PLTs) with vegetated urban soil. Four parking lots were instrumented, with temperature probes buried at different depths. Underground temperatures were measured during summer 2019, and the hottest days of the period were analyzed. Results show that the less mineral used in the surface coating, the less it warms up. The temperature difference at the upper layer can reach 10 °C between mineral and non-mineral PLTs. PLTs can be grouped into three types: (i) high surface temperature during daytime and nighttime, important heat transfer toward the sublayers, and low time shift (asphalt system); (ii) high (resp. low) surface temperature during daytime (resp. nighttime), weak heat transfer toward the sublayers, and important time shift (paved stone system); and (iii) low surface temperature during daytime and nighttime, weak heat transfer toward the sublayers, and important time shift (vegetation and substrate system, wood chips system, vegetated urban soil). The results of this study underline that pervious pavements demonstrate thermal benefits under warm and dry summer conditions compared to conventional parking lot solutions. The results also indicate that the hygrothermal properties of urban materials are crucial for urban heat island mitigation. |

In the current work, the energy crop miscanthus (Miscanthus × giganteus) was grown in ex situ conditions on agricultural soils presenting a Cd, Pb and Zn contamination gradient. After 93 days of culture, shoot and root growth parameters were measured. Soils and plants were sampled as well to study the TE accumulation in miscanthus and the effects of this plant on TE mobility in soils. Results demonstrated that miscanthus growth depended more on the soils silt content rather than TE-contamination level. Moreover, soil organic carbon at T93 increased in the soils after miscanthus cultivation by 25.5–45.3%, whereas CaCl2-extractible TEs decreased due to complex rhizosphere processes driving plant mineral uptake, and organic carbon inputs into the rhizosphere. In the contaminated soils, miscanthus accumulated Cd, Pb and Zn mainly in roots (BCF in roots: Cd " Zn > Pb), while strongly reducing the transfer of these elements from soil to all organs and from roots to rhizomes, stems and leaves (average TFs: 0.01–0.06, 0.11–1.15 and 0.09–0.79 corresponding to Cd, Pb and Zn respectively). Therefore, miscanthus could be considered a TE-excluder, hence a potential candidate crop for coupling phytostabilization and biomass production on the studied Metaleurop TE-contaminated soils. |

The concentration of potentially toxic elements was generally higher in stems than in leaves. Although P-fertilizers were added to contaminated soils under sustainable conditions (from 0.022% to 0.026% w/w), the average of leaf and stem biomass generally increased in the presence of P-fertilizers due to the changes in the speciation of phosphorus. Leaves of the investigated miscanthus may be of great interest as a catalyst in organic chemistry, since the Ca concentration was up to 9000 mg kg−1 DW. Stems represent a potential biomass that can be used as renewable resource of Lewis acids, currently used in organic syntheses (the sum of Zn, Cu, Mn, Fe, Mg, Si and Al was near 1000 mg kg−1 DW). The percentage of Cd and Pb in leaves and stems of miscanthus did not significantly change with P-fertilizers. Depending on the mesocosm and field experiments, it ranged from 0.004% to 0.016% and from 0.009% and 0.034% for Cd in leaves and stems, respectively, and from 0.004% to 0.015% and from 0.009% and 0.033% for Pb in leaves and stems, respectively. |

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. |

The results showed that Z1% and BW2% + Z1% were the most efficient amendments to reduce Cd, Cu, Pb, and Zn mobility, environmental availability, and phytoavailability in the M750 soil. The oxidation of Z1% allowed part of the Cu and Zn pools present in exchangeable or carbonate-bound forms (labile fraction) to complex in less mobile forms. In this soil, the metal chemical extractions (0.01 M CaCl2 and 0.05 M EDTA) and the DGT (diffusive gradient in thin films) devices to assess metal in soil solution and soil pore water (SPW) also highlighted the immobilizing characteristic of Z1%. In most cases, the addition of BW2% to Z1% (BW2% + Z1%) did not improve this effect, except for the dissolved Pb and Zn concentrations in the M750 soil solution. It was also observed that Cd, Pb, and Zn passed throughout DGT mimicking the biological cell membrane were reduced by all amendments of the M750 soil corroborating metal concentrations measured in rye grass shoots. In the MAZ soil, metals were less available as shown by their low extractability rate, low capacity of metal resupply from the solid phase to pore water, and low phytoavailability. The poor metal availability could be explained by the high levels of carbonate and organic matter contents in this soil. Nevertheless, a decrease of the Cu environmental availability and the Cu concentrations in rye grass shoots grown on the MAZ soil was also observed in the soil amended with Z1% alone or in combination with BW2%. From a health point of view, the most effective amendment to reduce human exposure through ingestion of soil particles for the M750 and MAZ soils was BW2% for Cd and BW2% + Z1% for Pb. However, the presence of rye grass minimized the amendments’ beneficial effects. |

In this sense, biomass of ryegrass was produced under greenhouse on two contaminated garden soils that have been amended with two successive additions of phosphates. After the first addition of phosphates, seeds of ryegrass were sown and shoots were harvested twice. A second seedling was performed after carefully mixing the roots from the first production (used as compost), soils and phosphates. Forty-eight weeks after starting the experiments, the concentrations of Cd, Pb, Zn, Cu, Fe, and Mn extracted using the rhizosphere-based method were generally lower than those measured before the addition of phosphates and cultivation (except for Pb and Fe in the most contaminated soil). The concentrations of metals in the shoots of ryegrass from the second production were lower than those from the first (except for Al). The best results were obtained with phosphates and were the most relevant in the lowest contaminated soil, demonstrating that the available metal concentrations have to be taken into account in the management of contaminated soils. In view of the concentration of metals defined as carcinogens, mutagens, and reprotoxics (e.g., Cd, Pb) and those capable to be transformed into Lewis acids (e.g., Zn, Fe), the utilization of ryegrass in the revegetation of contaminated soils and in risk management may be a new production of marketable biomass. The development of phytomanagement in combination with this type of biomass coincided with the view that contaminated soils can still represent a valuable resource that should be used sustainably. |

In: Applied Soil Ecology, vol. 138, pp. 99-111, 2019, (ACL). @article{Leclercq-Dransart2019, This study aimed at evaluating the impact of the use of fly ash-aided phytostabilisation as a method to manage highly metal-contaminated soils on soil functionality taking into account the soil and the litter qualities, the Diptera larvae communities and the microbial activity. To reach this goal, 70 parameters were studied. The main results showed that the two studied fly ashes Soproline® and Sodeline® had a positive influence on soil characteristics especially the availability of metals, nearly 14 years after amendment. Regarding biological parameters, no positive or negative effects were found by adding fly ashes to the soil concerning soil basal respiration and urease activity. The fungal activity was even enhanced. In the same way, the fly ashes had no negative effect on the Diptera larvae community and a greater richness of larvae was even found in amended soils. Thus, this study confirmed that aided-phytostabilisation using these fly ashes should be an advantageous technique to manage metal-polluted soils and to recycle industrial wastes. |

To limit health risks and to improve the soil quality, a study using calcium phosphates (monocalcium phosphate, dicalcium phosphate and a mixture of both salts) and Lolium perenne L was conducted. Through this preliminary investigation, we will try to shed some light about (i) the effects of a sustainable amount of calcium phosphates on the agronomic, biological (microbial and fungi communities) and physiological parameters (chlorophyll a and b, antocyanins, carotenoids) as well as the phytoavailability of potentially toxic metals and nutrients in time, and (ii) the potential use of contaminated biomass from ryegrass as a source of new valorisation ways instead of using it as contaminated compost by gardeners. Although slight variations in pH and significant increases of assimilable phosphorus after adding calcium phosphates were registered, the physiology of plants and the biological parameters were statistically unchanged. The germination of the ryegrass seeds was favoured with calcium phosphates regardless the contamination level of the studied soils. No clear effects of calcium phosphates on the microbial and fungi communities were detected. In contrast, results indicated relationships between the physicochemical parameters of soils, their contamination level and the composition of fungal communities. Indeed, for one of the soils studied, calcium could limit the transport of nutrients, causing an increase in fungi to promote again the transfer of nutrients. Surprisingly, the phytoavailability of Pb increased in the most contaminated soil after adding dicalcium phosphate and the mixture of phosphates whereas a slight decrease was highlighted for Cd and Mn. Although minor changes in the phytoavailability of potentially toxic metals were obtained using calcium phosphates, the ability of ryegrass to accumulate Zn and Ca (up to 600 and 20,000 mg kg−1, respectively) make possible to qualify this plant as a bio ‘ore’ resource. |

The environmental availability of PTEs was evaluated using a potential plant for revegetation of contaminated soils (ryegrass) and a mixture of low molecular weight organic acids. Despite the highest contamination level of B, the concentration of metals was highest in the ryegrass shoots grown on A for the two harvests. These results correlated well with those obtained using low molecular weight organic acids for Cd, Zn and Cu, whereas this mixture failed to represent the transfer of nutrients due to the presence of biological and physiological mechanisms. The statistical differences between the biomass of ryegrass obtained at the first and the second harvests were attributed to the decrease of available potassium, implicated in the growth and development of plants. Phosphates increased the ratios Zn/Cd, Zn/Pb and Zn/Cu up to 176 ± 48, 38 ± 6 and 80 ± 12, respectively, and made possible the reduction of the concentration of Cd and Pb in the shoots of ryegrass by 22% and 25%, respectively. The concentration of Zn in the shoots of ryegrass from the first and the second harvests grown on soil A were in the range 1050–2000 mg kg−1, making this plant a potential biomass to (i) produce biosourced catalysts for organic chemistry applications in a circular economy concept and (ii) limit human exposure to commercial Lewis acids. A preliminary application was identified. |

Pour apporter des éléments de réponse, des digestats de méthanisation ont été élaborés à partir de productions issues ou non de la zone affectée massivement par les émissions passées de Metaleurop Nord (Noyelles-Godault). Une culture de ray-grass a été réalisée en serre sur deux terres prélevées dans l’horizon labouré de deux parcelles situées ou non sous l’influence de l’ancienne fonderie de plomb et de zinc. Ce protocole expérimental a été complété avec une modalité comportant une fertilisation minérale NPK et un témoin (eau). Sur la terre non contaminée, l’ajout des digestats solides contaminés ou non n’a pas eu d’effet sur le rendement des feuilles de ray-grass alors que sur la terre contaminée a été constaté un accroissement notable de la biomasse. La contamination de la terre contaminée a été soulignée par la modalité témoin (eau) ; les concentrations en Cd, Pb et Zn dans les parties aériennes du ray-grass cultivé sur la terre contaminée sont respectivement près de 5, 2 et 5 fois plus élevées que celles se rapportant au ray-grass récolté sur la terre non contaminée. Les concentrations en Cd et Zn du ray-grass cultivé sur la terre non contaminée amendée n’ont pas montré de différence avec celles du témoin. L’apport de digestat issu des productions de la zone Metaleurop a augmenté les concentrations en Cd et Zn dans les feuilles de ray-grass cultivé sur la terre contaminée par rapport au témoin. Toutefois, cet accroissement n’a pas été significativement différent de celui constaté avec l’apport de digestat issu de végétaux non contaminés ou de fertilisants minéraux. Ceci laisse donc penser que l’accroissement des concentrations en métaux dans le ray-grass est davantage lié à la contamination des sols qu’aux contaminants apportés avec les digestats. |

Une expérimentation a été mise en place avec pour objectif d’étudier les effets de modes de gestion basés sur l’utilisation d’un amendement des sols, l’installation de communautés végétales et des pratiques usuelles d’entretien des espaces verts. Elle concerne une parcelle située dans l’ancien Bassin minier du Nord – Pas de Calais sur laquelle ont été déposés des matériaux multicontaminés issus de la carbochimie (usines de Mazingarbe). Au printemps 2018, 20 placettes d’une surface de 20 m² ont été définies. Le sol de 10 de ces placettes a été amendé au moyen d’un mélange de biochar de miscanthus et de compost de déchets verts. Les 10 autres placettes ont été utilisées comme témoin. A chacune de ces placettes correspond un type d’ensemencement particulier et un mode de gestion distinct. Ainsi, diverses essences végétales ont été semées. Il s’agit (1) d’un mélange d’espèces classiquement mis en oeuvre sur les espaces verts (ray-grass anglais, fétuque rouge gazonnante, fétuque rouge traçante et pâturin des prés), (2) d’un mélange d’espèces sélectionnées pour leurs comportements présumés vis-à-vis des polluants (stabilisation des polluants métalliques, rhizo/phytodégradation de certains polluants organiques (ray-grass anglais, agrostide stolonifère, fétuque rouge, trèfle blanc), et des mêmes espèces en implantation monospécifique avec (3) un ray-grass, (4) une agrostis stolonifère, (5) un trèfle blanc, et (6) une fétuque rouge. Une septième modalité correspond à l’installation d’une végétation spontanée. Aux espèces implantées en mélange et à la végétation spontanée, correspondent deux modes de gestion (tonte ou pas du couvert végétal). Durant les trois années d’expérimentation seront étudiés le comportement des polluants des sols, les effets des modes de gestion sur les communautés végétales et d’une façon globale, sur la fonctionnalité des sols. |

Depending on potentially toxic elements and their concentration, ryegrass shoots accumulate these elements in sufficient quantity to be used as a catalyst in organic synthesis. The analysis of Cd, Pb, Zn, Cu, Fe, Mn, and Al in ashes issued from the calcination of ryegrass shoots revealed that the concentration of Zn was highest (>7000 mg kg–1). The ratios between potential Lewis acids (Zn, Cu, Fe, Mn, and Al) to carcinogenic metals (Cd or Pb) were 191 ± 7 for LA/Cd and 235 ± 13 for LA/Pb, making the shoots of ryegrass suitable for the production of Zn-rich polymetallic biosourced catalysts. This material was used in the synthesis of idrocilamide under free-solvent condition, providing the drug in a good yield (69.9%). Data show that a limitation of waste, a maximization of the material incorporation in the process, a minimization of the steps, and an optimization of the stoichiometric factor are the main innovative factors in the current process in comparison with those previously reported. |

Samples were air-dried and crushed to pass through a 10-mm stainless steel sieve. Due to the high heterogeneity of garden soils in the studied area, much attention have been paid on the homogeneity of soil samples. After this step, the mass of sampled soils (48 kg) was divided to obtain four subsamples Each of them was divided in six replicates, unamended or amended using dicalcium phosphate (DCP) or monocalcium phosphate (MCP) or a mixture of these two compounds (MxP=75%DCP+25%MCP) The phosphorous amendments were added into the soil in small quantity (0.02 %) with the aim at reducing the environmental availability of carcinogenic metals and to increase the Zn availability (Figure 1) After the stabilisation period (2 months) in a greenhouse, 1 5 g of ryegrass seeds (Lolium perenne L.) were sown in the 24 containers. Eight weeks after sowing, ryegrass shoots were harvested, oven-dried at 40 °C and calcined at 500 °C in a muffle furnace (Nabertherm P330, Lilienthal, Germany). |

Since the publication of the 12 principles of this concept, many reactions in organic chemistry have been developed, and chemical products have been synthesized under environmentally friendly conditions. Lewis acid mediated synthetic transformations are by far the most numerous and best studied. However, the use of certain Lewis acids may cause risks to environmental and human health. This Review discusses the evolution of Lewis acid catalyzed reactions from a homogeneous liquid phase to the solid phase to yield the expected organic molecules under green, safe conditions. In particular, recent developments and applications of biosourced catalysts from plants are highlighted. |

However, the soil functionality becomes increasingly compromised due to contaminations caused by human activities. In 2006 and in 39 countries, the European Environmental Agency inventoried approximately 3 million of sites where pollutant activities occurred with more than 1 .8 million potentially contaminated sites (CGDD 2013). In 2012, the most frequently identified contaminants were metals (35 %), hydrocarbons (24 %) and polycyclic aromatic hydrocarbons (11 %). Until recently, the most common remediation technique was the excavation of contaminated soil and its disposal as landfill. However, this kind of method is considered inappropriate because it generates considerable disturbances, is expensive and economically unfeasible on a large scale . Thus, other remediation techniques (ex and in situ) have been developed to overcome these disadvantages . Among them, a technique consists in adding inorganic or organic amendments to the contaminated soils in order to decrease the mobility and bioavailability of pollutants in soils (Kumpiene et al., 2008; Vangronsveld et al., 2009; Bolan et al., 2014; Nejad et al., 2017) . The most often used amendments are phosphate compounds, liming materials, metal oxides and biochars, used alone or in combination (Waterlot et al., 2017; Lahori et al., 2017; Oustrière et al., 2017). The goal of the present work consists in evaluating the ability of two amendments (woody biochar and iron grit, used alone or in combination) to immobilize Cd, Cu, Pb, and Zn in contaminated soils under greenhouse conditions |

The different experimental strategies were plots planted with a tree mix or with a single tree species coupled or not with the use of fly-ashes as an amendment to limit metals mobility in soil. The breakdown of poplar litter on the four plots was monitored during 10 months. In parallel, colonization of litter bags by functional groups of mesofauna (Collembola and Acari) was followed. Two mesh sized litter-bags were used to allow distinguishing microbial and mesofaunal actions on the litter breakdown. We observed the breakdown of litter in four studied plots. Litter breakdown occurred faster in 3 mm litter bags than 250 µm ones during summer demonstrating the importance of mesofauna. Mixed plantation allowed faster litter breakdown than mono-specific plantation. A higher abundance of mesofauna and/or better abiotic conditions (moisture, shading…) could explain this result. Regarding litter breakdown and mesofauna, no significant difference was observed between the amended plots and those subjected to soil phytomanagement. However, communities of the studied area are disturbed since a low abundance of detritivores was observed. This could explain also the slower litter breakdown than expected in our study. To conclude, among the phytomanagement methods tested, mixed plantations could provide a benefit for the restoration of degraded soils. By contrast, the use of fly-ashes does not seem to have any effect on the functionality of ecosystem neither on the litter breakdown process nor on the abundance of mesofauna. |

Miscanthus x giganteus was selected to phytostabilize polluted soils surrounding the former lead smelter Metaleurop Nord, in Northern France. The aim of the current study was to determine the impact of miscanthus plants on restoring the corresponding soil functionality. Ex situ experiments revealed that soil biological activities (basal respiration, fluorescein diacetate hydrolytic activity, acid phosphatases, laccases and ureases) as well as microbial biomass carbon increased in contaminated soils cultivated with miscanthus, compared to unplanted soils. These results verify the capacity of miscanthus to restore polluted soil functionalities, indicating the positive effect of phytostabilization on soil biological activities. In conclusion, revegetating polluted soils with miscanthus plants can restore their capacity to perform biochemically and biologically. |
