Average exceeded by 13 times during the year there was one record high contamination benzapirenom air. As the most typical chemical carcinogen environment, it is dangerous to humans even at low concentrations, because it has the property of bioaccumulation.
The main sources are benzapilene environmental tobacco smoke, heating (burning wood, coal or other biomass), automobile transport, asphalt, stone and coal tar. The maximum permissible average concentration of benzopyrene in air - 0, 1 ug / 100 m³.
