THE ASSESSMENT OF THE SOIL'S POLLUTION DEGREE ASSOCIATED ON THE OIL FIELDS OF UDMURTIA

Annotation. The problem of soil pollution of one of the oil fields of the Udmurt Republic is considered. The sources of pollution and the degree of soil disturbance were revealed. Background agrochemical properties of soils and total pollution index were studied. The soils of the studied areas have satisfactory agrochemical indicators: the reaction of salt extraction is neutral, low hydrolytic acidity, high degree of saturation, the average amount of absorbed bases, low humus content, the average content of mobile phosphorus, low-exchange potassium. The exchange of sodium (0,013 %) soils are characterized as neolocality. According to the indicators of the dense residue, the soils are medium-saline (0.23%). According to the environmental monitoring data, a low level of pollution with oil products (0.56 g/kg of soil) was determined according to Yu. I. Pikovsky's gradations. In General, the results of studies assessing the degree of soil pollution showed that the latter is capable of self-healing of its original properties.
Keywords: toxic soil pollution, monitoring, oil, field, soil restoration, oil transformation.
