The immobilizing effects of wood biochar (BW2%) and iron grit (Z1%)
applied alone or in combination (BW2% + Z1%) to agricultural (M750)
and brownfield (MAZ) soils highly contaminated by metals were assessed
in a greenhouse experiment. 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
