Abstract
The influence of exogenous form of heavy metals intake on their transformation in the soil is determined during model
experiments. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition
various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is
observed. It is established that Cu accumulates mainly in the fraction connected with organic matter; Zn accumulates in residual
fraction and in the fraction connected with ferric oxide and manganese oxide by consecutive fractionation technique.
