The content of Cu, Zn, Co, Ni, Pb, Cd, Cr, Mn was determined in samples of irrigation water, irrigated and non-irrigated soils of the Lower Dnieper river of Ukraine. The vertical distribution of heavy metals in soils was also determined. The results indicated that irrigation water is not contaminated, and its use cannot lead to excessive accumulation of heavy metals in the soil. The content of heavy metals in the humiferous horizons of both soils is at the background level. The content of mobile forms of Zn, Cd, Ni, Cr, Mn in the humiferous horizon of irrigated soils is slightly higher than in non-irrigated soil. This may be due to a significant change in the soil hydrological regime during irrigation and an increase in the solubility of elements. Most of the elements are characterized by accumulation in the upper humiferous horizon, its content decrease in the first transitional horizon, and transition to the parent rock and in the gleyic horizons.
