Rezumat

Linden litter and snow cover accumulate large amounts of substances (including harmful ones), mainly coming from the atmospheric air. Therefore, both snow and litter can be indicators for an indirect assessment of the state of the air pollution level. Observations have shown that the concentration of pollutants in melt water and plant litter is several times higher than in the atmospheric air. Harmful components in the future can enter the upper soil layer, as well as groundwater and exert a negative effect. The aim of our study was to monitor litter and snow cover near three springs (two in the city of Ivanovo and one in its satellite town – Kokhma). In the motoring performed, the content of harmful impurities in the studied samples of melt water of the snow cover was controlled by standard methods of chemical and physicochemical analysis (potentiometric, titrimetric, photometric and atomic absorption) in accordance with the standards for the content of substances in water bodies for fishery purposes (TLVrh). Snow samples were taken at five points around each of these springs, as well as near the nearest highways. The pH value and the content of compounds Cu, Cr, Mn, Pb, Zn, Al, Co, Cd, Ni were also under control. In addition to melt water, the level of air pollution, samples of linden blossom and lime litter was also analyzed according to the list of 139entrali pollutants characteristic of the territories under consideration. Data on priority pollutants were obtained from the research paper by S.A. Buimova, A.G. Bubnov ―Comprehensive assessment of the quality of spring water on the example of the Ivanovo region‖ (2012). The data obtained from the studies of the snow cover showed that all the studied samples were characterized by an increased content of Cugen, Zn2+, Pb2+ compounds. At the same time, in most cases, the presence of pollutants was higher in samples taken during the warm period of 2019. Based on the monitoring results, the risk from air pollution by Zn2+, Mn2+ and Со2+ compounds for humans, plants and the biosphere as a whole under chronic exposure was assessed. The estimated values can be attributed to an unacceptable (high) degree of risk of atmospheric pollution.
