| 摘 要： | 本研究采集了长春市2017年秋季大气中的PM2.5样品共30个，采用气相色谱质谱仪（GC-MS）分析了样品中17种多环芳烃（polycyclic aromatic hydrocarbons，PAHs）的浓度和组成特征，运用比值法和主成分分析法确定PAHs的污染来源，并通过计算苯并（a）芘等效致癌浓度和终身致癌超额危险度进行健康风险评估.结果表明，长春市秋季PM2.5平均质量浓度为（50.84±12.23）μg·m-3，有机碳（OC）和元素碳（EC）含量分别为（17.07±5.64）μg·m-3和（1.33±0.75）μg·m-3，占PM2.5总量的37%；PAHs总浓度为（15.69±5.93）ng·m-3，以中高环数的PAHs为主，占总PAHs的84.26%；长春市秋季大气中PAHs主要来源于机动车尾气排放（44.48%） > 煤燃烧（29.16%） > 生物质燃烧（26.36%），本地交通（汽油车）排放是主要污染源；苯并（a）芘等效致癌平均浓度在1.55~5.38 ng·m-3之间，总致癌等效平均浓度为（6.44±1.53）ng·m-3，总体处于轻微污染水平；通过呼吸摄入PAHs对成年女性健康危害最大，其次是成年男性和儿童，但所有人群的终身致癌风险值均未超过1×10-6，其健康风险处于可接受水平.
