Abstract—

This study presents the results of an assessment of the pyrogenic factor’s contribution to atmospheric pollution in territories of the Tomsk region, based on the analysis of heavy metal (Zn, Pb, Cu, and Cd) atmospheric deposition within the Bakchar Bog (the north-eastern part of the Great Vasyugan mire). Atmospheric depositions of Cu, Pb, Zn, and Cd were analysed using the passive dust deposition method, measuring particle content per m² during 2018–2019. Data analysis showed an excess of Zn in atmospheric deposition that persisted for three years after a fire in a drained bog, during both summer and winter observation periods, with a maximum value of 3.63 mg/m² per month in 2018. The impact of the fire on Cd and Pb content persisted for two years after the fire. The Cu content of atmospheric depositions is not affected by the pyrogenic factor. The analysis of seasonal dynamics showed that the Zn, Cd, and Pb content of atmospheric depositions was influenced by wild fires that cause the transfer of pollutants at both local and regional scales.

监测大Vasyugan矿区内Zn，Cu，Cd和Pb的大气沉积

摘要—

这项研究基于对Bakchar沼泽（北部地区）中重金属（Zn，Pb，Cu和Cd）大气沉积物的分析，提出了评估托木斯克州地区热源因子对大气污染的贡献的结果。大Vasyugan泥潭的东部）。使用被动粉尘沉积法分析了Cu，Pb，Zn和Cd的大气沉积，测量了2018-2019年期间每m ^2的颗粒含量。数据分析表明，夏季和冬季观察期内，排水沟中的大火之后，大气沉积物中的锌过量持续了三年，最大值为3.63 mg / m ^2。火灾在2018年每月增加。火灾对镉和铅含量的影响持续了两年。大气沉积物中的铜含量不受热解因素的影响。对季节动态的分析表明，大气沉积物中锌，镉和铅的含量受野火的影响，这些野火导致污染物在地方和区域范围内的转移。
