Abstract

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).

持久性有机污染物向俄罗斯北极的全球大气运输

摘要

提出了评估《斯德哥尔摩公约》中2015-2017年在《斯德哥尔摩公约》中列出的持久性有机污染物（POP）造成的空气污染水平的实验结果。持久性有机污染物的清单包括多氯联苯，有机氯农药和多溴联苯醚。显示POP浓度的范围，并计算观察期内的统计特征（均值，中位数）。在分析诊断比率和温度依赖性的基础上，考虑了全球运输源的特征。持久性有机污染物浓度的变化范围很大，这取决于环境因素和来源类型（本地来源或全球运输）。
