| description | The relevance of studying chemical composition of solid sediment in snow cover of Usolye-Sibirskoe was predetermined by the data of the Ministry of Natural Resources of Russia, given in the State Report «On the State and Environmental Protection of the Russian Federation», which show a significant deterioration of the environmental situation in the period from 2012 to 2017. In 2020 Irkutsk Region took the third place among the regions of Siberia in terms of industrial emissions into the atmosphere. Five of the most polluted cities – Bratsk, Zima, Cheremkhovo, Usolye-Sibirskoe and Shelekhov – were noted, in which, despite more modern treatment facilities currently used, pollution indicators increased compared. The work is particularly relevant due to the fact that Lake Baikal – a unique natural object classified as a World Heritage Site – is located at a distance of only 120 km from the research area. The Angara River flowing from the lake Baikal, the main source of drinking water for the population of coastal cities, flows in close proximity to industrial production areas.
Objective: assessment of the ecological state of the air in Usolye-Sibirskoe based on the results of snow-geochemical monitoring and geoinformation mapping.
Objects: solid sediment of snow cover in Usolye-Sibirskoe, Irkutsk region.
Methods. Chemical composition of the solid sediment of the snow cover was determined by the ISP-MS method, mercury was analyzed by atomic absorption on the RA-915+ spectrometer, and the mineral composition of the solid snow sediment was determined by X-ray spectral electron probe microanalysis.
Results.The paper presents the results of studies of mineral and microelement compositions of solid sediment of snow cover in the functional zones of Usolye-Sibirskoe. Chemical elements and minerals – markers of technogenic sources of pollution – have been identified. With the help of GIS, mapping was performed, the results of which helped to identify halos with a weak, medium and strong degree of contamination. |
