Soil leaching with progressively increasing EDTA concentrations successfully removed increasing shares of Pb, Zn and Cd from the soil. A set of chemical extraction tests and metal accumulation in whole bodies of the earthworm species Eisenia fetida confirmed the effectiveness of such remediation approach. The earthworms were however not able to discriminate between non-remediated and remediated soils. This is one of the scarce reports discussing the problematic use of earthworm avoidance test for the assssment of non-artificially polluted soils.

EDTA leaching of soil polluted with copper successfully removed the biologically most available share of Cu. We exposed the remediated soil to autochtonous earthworm species Lumbricus terrestris for the simulation of soil botic factors affecting remediated soil after its re-introduction into the environment. The comparison of earthworm casts with the bulk soil showed just limited erathworm influence on Cu mobility in soil. The study showed that the proposed remediation is long lasting and is applicable for the reclamation of polluted vineyard soils.
