The article presents the results of the studies (in 2018 and 2019) of the level of accumulation of polychlorinated biphenyls (PCBs) ? the most toxic compounds from the number of persistent organic pollutants (POPs) in the snow cover (SC) of the territory of Almaty agglomeration, area of about 940 thousand hectares. The contamination of PCB SC has been established, especially in urban areas and adjacent to large industrial hubs. In snow samples up to 29 individual PCB congeners are identified, which is an indicator of the presence of various sources of pollution of these pollutants of the region?s natural environment. In samples of snow with a wide spectrum of congener composition, strictly controlled «marker» (indicator) and highly toxic dioxin-like congeners are registered. The main sources of PCB contamination in the agglomeration area are identified.
