摘要/Abstract

摘要： 采集了北京市奥林匹克公园2017年12月至2018年6月的67个PM_2.5样品，对PM_2.5中多环芳烃（PAHs）在采暖季和非采暖季的污染情况、浓度分布特征、来源和健康风险等进行研究。利用GC-MS对16种PAHs进行了检测分析。采暖季和非采暖季的PAHs均值分别为213.6和52.5 ng·m^-3。利用比值法和主成分分析对PAHs进行源解析的结果显示，北京市城区采暖季16种PAHs主要来源于煤和石油等化石高温燃烧排放，非采暖季主要来源是机动车尾气排放；ILCR暴露风险评估模型评估表明，人群呼吸暴露在北京大气中具有潜在致癌风险。

Abstract: We collected 67 particulate matter (PM_2.5) samples in the Beijing Olympic Park from December 2017 to June 2018 to examine the concentration, distribution characteristics and sources of polycyclic aromatic hydrocarbons (PAHs) in PM_2.5, and assess the health risks during the heating season and non-heating season. The PAHs were detected by the GC-MS. The average values of the total concentrations of 16 PAHs associated in PM_2.5 in the heating season and non-heating season were 213.6 and 52.5 ng·m^-3, respectively. The molecular diagnostic ratios and principal component analysis were applied to apportion the sources of PAHs. The results showed that the sources of PAHs were mainly derived from the combustion of petroleum and coal during heating period, and from vehicular emissions during non-heating period. The health risk evaluation of PAHs was conducted by the model of incremental lifetime cancer risk (ILCR). There were potential carcinogenesis risks when exposed to PAHs associated in PM_2.5.
