Ecological and hygienic situation in the area of the location of a chemically hazardous facility

Introduction. The main activities of the branch of the Scientific and Production Center for Rocket Fuel Components are the production of hydrazine and utilization of rocket technology on liquid fuel. These processes are potential sources of pollution of the territories adjacent to the facility. The purpose of the work is to assess the ecological and hygienic situation in the area of the location of the facility as a priority part of ensuring the safety of the population. Materials and methods. The analysis of environmental objects was carried out on the basis of data from production control and environmental monitoring of the enterprise, materials of the MRU No. 153 of the Federal medical and biological agency of Russia, as well as the results of its own research. Results. Over the period of 2014–2020, the quality of atmospheric air in the area of influence of the facility mainly met sanitary requirements. In water samples from surface reservoirs, concentrations of specific, general industrial pollutants and metals did not exceed hygienic standards. The drinking water of the non-centralized water supply in nearby settlements mostly met the established requirements, with the exception of cases of increased barium content, which reached 1.2 MPC in the non-centralized water supply system of the village of Rumstikha. In the soil cover, the content of unsymmetrical dimethylhydrazine in all samples, and dimethylamine in most cases was lower than the sensitivity of the determination method. Metal concentrations did not exceed the relevant hygienic standards. Limitations. Are due to a number of uncertainties related to incomplete information about all possible contaminants of environmental objects, as well as the insufficient sensitivity of some measurement techniques. Conclusion. It is concluded that there is no adverse impact of the economic activity of this chemically hazardous facility on the territory adjacent to the facility.
