Study of soil enzymatic activity of oil fields in the Republic of Kalmykia

Abstract

Pollution of soils with oil and oil products, for today, very actual problem. In the present study, the content of soil enzymes (catalases, phosphatases, ureases and invertases) in the soils of Kalmykia oilfields has been studied to diagnose oil pollution. The content of oil products in the soils of oilfields is studied. As a result of research, it is established that the most informative soil enzyme in relation to oil pollution is catalase. Activity of phosphatase, ureases and invertase even in the background soils is minimal, as the studied soils show weak biological activity. It is proved that the change of catalase activity, as a rule, is in direct dependence on oil content in soil, the higher the content of oil and oil products in soil, the lower the activity of catalase.
