Sanitary-hygienic characteristics of the area of positioning for the disposal of rocket technics

There was executed the sanitary-hygienic assessment of residential areas in the zone of possible impact of industrial activity of the Center for the elimination of Intercontinental ballistic missiles affiliated to the Federal State Unitary Enterprise “Center for Operation of Ground-Based Space Infrastructure Facilities” located in the Nizhny Novgorod region. There were performed full-scale studies of air samples, water reservoirs and sources of drinking water, the soil on the content of components of liquid rocket fuels and their degradation products. Studies have shown full-time work enterprises not to be accompanied by the emission of unsymmetrical dimethyl hydrazine, Tetramethyl-2-tetrazene, NDMA into the environment. In samples of water from open stagnant water bodies there was detected both dimethylamine in concentrations exceeding MPC by 1.1 - 1.3 times, and formaldehyde in the concentration below the MAC. All soil samples also contain FA and DMA in concentrations significantly lower than the MPC. As, Be, Cd, Pb in drinking water was not detected within the sensitivity of the method, Ni content, Zn, Mg, Mn, Al does not exceed hygienic standards. Fe content in the water of centralized water supply amounted to 1.5 MAC.
