This standard is used for the determination of EDTA(Ethylendiamintetraacetat)-extractable heavy metals in soils and applies taking into account the general provisions of ÖNORM L 1053. The method determines primarily bound in a complex and at the surface of soil aggregates accreted binding forms of heavy metals. The determined concentrations correlate only partially with the uptake by plants. The possible values allow together with the results of extraction with strong mineral acids (ÖNORM L 1085) and with the results of extraction with salt solutions (ÖNORM L 1094, parts 1-3) a better assessment of contamination. Heavy metals geogenic origin generally with the same total salary show much lower solubility than those of anthropogenic origin.
