Influence of light fractions of petroleum hydrocarbons on the biological activity of soils

Abstract

Experimental studies were conducted to assess the effect of oil’s light and medium fractions on the soil’s biological activity. Enzymes at different stages of petroleum’s hydrocarbons biodegradation are considered. The results of the research were the biological activity of soils (soil microbiocenoses and enzymatic activity) contaminated with oil’s light and medium fractions. The results can be used when choosing the direction of oil-contaminated soil’s recultivation. The data can also be used as an indicator of the degree of soil contamination with oil products and its duration.
