Features of oil products content distribution in soils, road dust and snow according to the mega profile in the Rostov region

Abstract

In the last few decades, the enormous scale of crude oil extraction, transportation and processing has caused widespread pollution of soils with crude oil and oil products. Thus, its permanent presence in the environment, and, as a consequence, in soils, is due to natural and anthropogenic origin. The authors have conducted expeditionary research in order to take soil, dust and snow samples along the route "Margaritovo (coast of the Sea of Azov) – Shakhty (Eastern Donbass)". The profile extension is more than 150 km. The oil products mass concentration has been determined in the samples collected. The data set analysis has showed that the oil products content in the soils of the Rostov region should be assessed as varying from acceptable to average. It is concluded that road dust and snow are one of the dominant sources of soil pollution in the Rostov region with oil products.
