Determination of toxicity of soil contaminated with by of petrochemical hidrocarbons

Abstract

Abstract This work presents the results of experimental studies of the effect of the distillation residue of petrochemical industry containing heavy hydrocarbons on soil toxicity using phytotesting methods. Spring wheat «Omskaya-36» seeds were used as a test object. The experiments were conducted according to the certified method for determining soil toxicity by seed germination and measuring the average length of watercress seedlings (Lepidiumsativum) FR.1.39.2016.24117. The studies were conducted in laboratory conditions for three types of soil: gray forest, sod-podzolic, leached chernozem. The assessment was determined by such parameters as seed germination, underground, aboveground and the total seedling length. The studies revealed a negative effect of the petrochemical distillation residue on the studied soil types. The results showed the effectiveness of using Lepidiumsativum to determine the toxicity of the analyzed soils containing toxic hydrocarbons. The developed method can be used for the analysis of the pollutants toxic effect on soils.
