摘要
利用采样及分析检测程序对青岛市近岸6个功能区大气气溶胶中多环芳烃化合物的浓度进行了为期1年的监测，评价了该地区大气中多环芳烃的水平。青岛近岸大气气溶胶中PAHs平均浓度范围在16（清洁对照区）～308ng／m^3（工业区），PAH总平均浓度为74．5ng／m^3。冬季浓度水平高于其他季节，工业区浓度水平高于其他功能区。以相关分析法对获得数据进行分析，结果表明机动车辆尾气排放、煤的燃烧、燃料和油品的不完全燃烧是多环芳烃的可能来源。
Atmospheric concentrations of polycyclic aromatic hydrocarbons （PAHs） were measured during various seasons at Six different cities/locations along Qingdao＇ s coastal areas. The annual average PAH concentration ranged from 16 （at a clean control site） to 308 ng· m^-3（at an industrial site）. The average total particu late PAHs concentration was 74.5 ng/m^3 with higher concentration＇ s occurred in winter. Based on a yearround dataset, the sources of PAHs in the air over Qingdao were examined by correlation analysis. The results indicated that vehicle emissions, coal combustion, incomplete combustion and pyrolysis of fuel and oil burning were the main sources of PAHs over Qingdao coasted areas.
