The article assesses the content of petroleum products and heavy metals (cadmium, copper, zinc, lead) in the soils of roadside territories of Kalininsky administrative district of Tyumen. The content of petroleum products and heavy metals (gross and mobile forms) in soil samples collected near petrol stations and road crossings was analyzed. The correlation between the intensity of the traffic flow and the gross content of heavy metals is shown. According to generalized data, the content of petroleum products near the studied road junctions is 30% higher than in the area of gas stations. The gross content of lead in the soils of roadside areas near automobile intersections is 64% higher. But the gross content of cadmium, copper and zinc is lower than near gas stations. The absence of exceeding the standards for the gross content and mobile form of the studied heavy metals, with the exception of cadmium, was revealed. The relationship between the intensity of the traffic flow and the gross content of heavy metals is direct, characterized by positive correlation coefficients from 0.37 to 0.88. The closest relationship between the intensity of the traffic flow and the level of accumulation of oil products has been established.
