The article presents the results of the study conducted on the territory of the Almaty agglomeration (AA) in the first half of 2019. During the expeditionary studies, sampling was carried out at 30 permanent points established taking into account the degree of anthropogenic load and sources of technogenic pollution. The content of trace elements (TE) in the snow was determined by a flame atomic absorption spectrometric method using an AA-7000 spectrophotometer with a hollow cathode lamp and with a nozzle burner operating on an acetylene-air mixture. The paper considers the amount of content of copper and lead in the snow, as well as the nature of their distribution over the study area. Calculations were carried out on the number of depositions of the TE in question per unit area over the territory of the agglomeration, with the allocation of zones experiencing the highest technogenic load.
