Abstract: | Background, aim, and scope Soil remediation with ethylenediamine tetraacetic acid (EDTA) leaching is capable of removing only part of the total metal
concentration in the soil, mostly the labile, bioavailable metal species (metal bioavailability stripping). However, reintroduction
of remediated soil in the environment exposes the soil to various environmental factors, which could potentially shift nonlabile
residual metals back to labile bioavailable forms. We studied the effect of autochthonous earthworm species as model biotic
environmental factor on the fractionation and bioavailability of Cu residual in soil after remediation. |
