【摘要】 对北极气溶胶采样,测定了颗粒相中多环芳烃以及有机碳和元素碳,根据多环芳烃的组成及分子标志物参数,对采样区域内多环芳烃的来源以及传输途径进行分析。结果显示,该地区的多环芳烃污染既有燃烧来源也有石油来源,其中又以植物和煤炭的燃烧为主,其输入途径主要是大气传输,有机碳和元素碳同步传输。更多还原

【Abstract】 Air samples collected in the arctic area were analyzed for the potential mechanism of input sources and transport pathways of PAHs.The results showed that both combustion processes and release of uncombusted petroleum products were the sources of PAHs,among which combustion of biomass and coal was the dominant one.The atmosphere transportation was the main transport pathway of PAHs.The OC and EC were transported simultaneously.更多还原
