Abstract

The influence of oil pollution and concomitant salinization of chernozem typical in a fi eld experiment has been studied. It is shown that the oil intake of 2 and 3 g·kg-1 with or without sodium chloride 1 g·kg-1 does not have a negative effect. It was found that under the influence of salinization, the content of mobile forms of heavy metals increases by an average of 1.5 times. The analysis of the content of heavy metals in crops cultivated on the territory of the Republic of Bashkiria (Pisum sativum L., Triticum aestivum L.) aft er contamination with oil and sodium chloride was carried out both individually and jointly in a fi eld experiment. The content of mobile forms of heavy metals in the soil under the influence of two crops is different, which is due to the physiological characteristics of crops and the influence of pollutants.
