Effect of Heavy oil Products on Еcological State of Soils and Ground Waters

Abstract

Spotty soil contamination was registered in the territory. It was established that the maximum, field (minimum) and capillary moisture capacity figures depend on the content of heavy oil products in soil. The content of heavy oil products in soils is 2 to 3 times higher than the recommended norm for vegetation development and 10 to 14 times higher in comparison to background pollution figures in the north, west and up to the border of the SPZ 300 meters away matching the pollutants transfer path. Perennial ryegrass (lawn) plants in soil with the highest content of heavy hydrocarbons are higher than reference species, the yield is similar to that on the reference plot. The content of heavy oil products in the rest of the examined territory is at the background level. The content of oil products in ground water samples with ground waters high and close to the river indicates the ingress of contaminants into ground waters.
