摘要
The experimental results of evaluating levels of air pollution with persistent organic pollutants (POPs) listed in the Stockholm Convention at Amderma and Tiksi stations in 2015-2017 are presented. The list of POPs includes polychlorinated biphenyls, organochlorine pesticides, and polybrominated diphenyl ethers. The ranges of the POP concentration are revealed and the statistical characteristics (mean, median) over the observation period are calculated. Based on the analysis of diagnostic ratios and temperature dependences, the features of global transport sources are considered. A wide range of variations in the concentration of POPs is shown that depends on environmental factors and the source type (local sources or global transport).
