  abstract = {{C}ompost addition to soil improves soil fertility, valorizes organic wastes and is expected to decrease the mobility of toxic metals by sequestration into soil organic matter. {O}n the contrary, we hypothesized here that compost addition may increase metal mobility in metal-rich soils. {F}or that, we studied the mobility of copper, zinc, nickel and chromium in {F}erralsols by kinetic extraction with ethylenediaminetetraacetic acid. {R}esults show an increase in the extractable metal pools in the compost-amended {F}erralsols, amounting up to 500 mg of nickel per kg and 100 mg of chromium per kg, representing 10% and 1% of the total concentrations. {T}he enhanced mobility of nickel and chromium arise most probably from soil properties, while the enhanced mobility of copper and zinc should mainly originate from compost properties. {W}e conclude that addition of compost may induce the release of toxic metals in substantial amounts under specific conditions.},
