The pollution by oil products causes the increase in the reductive compounds content in the studied soils. Their content decreases with time. It results in the increase in pH and in the following changes in the solubility of microelements in 0.01 M EDTA: an increase of Cu (in the acid soil, pH 6), Fe (at pH 7), and especially of Mn (at pH 7); an decreases of Zn in all soils, Fe (at pH 7), Cu ( at pH 6), and Mn (at ph
