摘要
本文对新疆准东煤矿开采区域降尘中16种多环芳烃(PAHs)的含量、来源及健康风险进行了分析。结果显示,新疆准东煤矿开采区降尘中PAHs的含量在1.07~8.34mg/kg,PAHs的含量组成基本表现为五环组分>四环组分>三环组分>六环组分>二环组分;降尘中PAHs的来源主要是煤炭、木材和草的不完全燃烧,交通污染也会影响部分采样点;研究区域内,暴露途径的终生致癌风险(ILCRs)均是皮肤接触>手口摄>呼吸吸入,降尘中PAHs的主要暴露途径是皮肤接触,降尘中的PAHs是存在潜在健康风险的,对人体健康会带来潜在的影响。
In this paper,the content,source and health risks of 16 polycyclic aromatic hydrocarbons(PAHs)in the dustfall in the mining area of Zhundong Coal Mine in Xinjiang were analyzed.The results show that the content of PAHs in the dustfall of the mining area of Zhundong Coal Mine in Xinjiang is 1.07~8.34 mg/kg,and the content of PAHs is basically five-ring component>tetracyclic component>tricyclic component>hexagonal component>two-ring components;the source of PAHs in dustfall is mainly incomplete combustion of coal,wood and grass,traffic pollution will also affect some sampling points;in the study area,the incremental lifetime cancer risk(ILCRs)of exposure pathways are skin contact>hand photography>breathing inhalation,the main route of exposure for PAHs in dustfall is skin contact,PAHs in dustfall are potentially health risks that have potential effects on human health.
