Standardization of heavy metals and oil content by biological indicators in the southern chernozems of the Taman
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
This paper provides an assessment of the resistance of Taman chernozems to contamination with heavy metals (Cr, Cu, Ni, Pb) and oil by biological parameters. As a rule, upon contamination of the Taman chernozems, a significant reduction was observed in the total bacterial count, activity of catalase and dehydrogenase, cellulolytic activity, abundance of the Azotobacter genus bacteria and in the radish germination intensity. The extent of the deterioration in biological properties was determined by two factors: the chemical nature of the metal and its amount in the soil. As a rule, a direct relationship was observed between the concentration of the pollutant and the degree of deterioration of the soil properties in this study. The metals studied had shown different ecotoxicity with respect to the chernozems of Taman: Cr > Cu = Ni = Pb Regional norms for the maximum allowable content of Cr, Cu, Ni, Pb, and oil in the Taman southern chernozems based on a disturbance of the ecological functions of soils were proposed.
