Features of hygienic assessment of atmospheric air quality in the area of the location of the enterprise for the production of mineral fertilizers

Introduction. The problematic environmental situation in the industrialized territories requires precise management decisions to ensure the excellent quality of atmospheric air to protect public health. Information on the atmospheric air quality is based on data from various monitoring systems: socio- hygienic, environmental, production control, as well as the results of control measures carried out by Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor) and Federal Service for Supervision of Natural Resources of the Russian Federation (Rosprirodnadzor)). Materials and methods. The analysis of normative permissible emissions, sanitary protection zones projects, the results of socio-hygienic and environmental monitoring, production control, as well as carried out own laboratory, and instrumental laboratory studies of 130 samples of atmospheric air in the sanitary protection zone of the chemical industry enterprise and the nearest residential area. The research was based on the North-West Public Health Research Centre and the chemical-analytical centre “Arbitrage”, D.I. Mendeleev Research Institute for metrology. Results. According to various monitoring systems and the results of own research, on the territory of residential buildings, the concentrations of pollutants did not exceed the MАC, mainly corresponded to the design values. However, the ammonia content in the atmospheric air on the territory of the nearest building to the enterprise exceeded the calculated design values by three times. At the border of the industrial site of the enterprise for ammonia and diPhosphorpentaoxide, concentrations comparable to the MАC were recorded, while hydrochloric acid and gaseous fluorides were not detected either at the border of the industrial site or in the nearest residential development. Conclusions. The programs of air quality control monitoring are based on the research and analysis of the project documentation. The developed scheme for monitoring atmospheric air can be applied to assess atmospheric air quality in areas around mineral fertilizer production enterprises.
