RESUMO
The paper presents information about the content of benzo(a)pyrene in soil samples of petroleum products and the content of heavy metals (iron, copper, lead, arsenic, manganese, chromium, cadmium and mercury) in the soil and hair samples of children. Soil samples and hair were taken in October 2014 in the north-western part of the Yamal-Nenets Autonomous District. The values obtained were compared with the approximately permissible levels and maximum allowable concentrations adopted in the Russian Federation. Levels are determined compounds in the soil in general do not exceed the allowable concentrations. In hair samples there was noted marked exceeding of the recommended values for zinc, copper, chromium and iron 10%, 16.7%, 83.3% and 100% samples, respectively. The cause of the high iron content in the hair samples may be due to the quality of consumed water, which is characterized by low mineralization and high iron content. Increased chromium content of more than 80% of the hair samples can be caused, as in the case of iron, the quality of water consumed, but also a high proportion of local foods in the diet of people, rich by chromium. A conducted study on the state of the environment in the village, away from areas of hydrocarbon production, indicates to the low importance of anthropogenic impact.
