Ecological Monitoring of the Areas of the Angara A5 Launch Vehicle Separation Parts Fall

An ecological survey of the areas of the Angara A5 launch vehicle separation parts fall before and after its launch from the Plesetsk Cosmodrome in 2014, 2020 and 2021 was carried out. The acidity, Eh, ionic composition (Ca 2+ , Mg 2+ , HCO 3 – , Cl – и SO 4 2– ), mineralization, COD, content of petroleum products and kerosene in snow samples after melting were determined. In the surface layer of air, the concentrations of NO, NO 2 , CO and kerosene content were determined in real time using the gas analyzer “GANK-4”. It is concluded that chemical pollution of snow cover and surface layer of atmospheric air in the areas of the Angara A5 launch vehicle separation parts fall has not been revealed, and there is only insignificant local mechanical pollution of landscapes by elements of structures with damage to vegetation and soil cover in the places where fragments of the launch vehicle's separation parts fell.
