Evaluation of Сarcinogenic Risks for the Population in the Area of Aluminum Production Emissions

Abstract

The analysis of the environmental burden on the benzo(a)pyrene and formaldehyde on the rural population living in the zone of influence of aluminum production on the example of Shelekhov district of the Irkutsk region. Determine the load on the population through inhalation of contaminated air (inhalation load), in the use of food grown in contaminated soil (potatoes, carrots), well water, accidental swallowing of water while (oral load), via skin intake (skin load). Calculated individual and population-based cancer risks for the rural population. It was found that for the rural population the greatest contribution in the risk value (66%) is an oral route of carcinogens by eating vegetables (potatoes, carrots) grown on contaminated soils. For the urban population living in the area of aluminum production emissions, individual cancer risk is mainly due to the body intake of formaldehyde and benzo(a)pyrene through the air inhalation.
