Sanitary and hygienic characteristics of air quality
The study of air quality of the investigated localities revealed some variation in concentrations of gases and impurities (daily average concentration of suspended solids, nitrogen dioxide, sulfur dioxide and carbon monoxide) from the sanitary standards (MPC<sub>da</sub>). Isolated cases of increase in the concentration of benzo(a)pyrene in the air in rural streets points to environmental degradation countryside. This may have implications for public health (the growth of cancer pathology).
