摘　　要：采用气质联用技术(GC/MS)对上海市大气颗粒物中美国EPA优先控制的16种多环芳烃进行定量研究.结果显示,冬季PAHs浓度最高,夏季浓度最低;绝大多数的PAHs存在于0.43～2.1μm的粒径范围内;在粒径分布上,三环、四环、五环的PAHs基本上呈单峰分布,在0.43～1.1μm时达到浓度最高值.The pollution characteristics of EPA priority controlled PAHs in aerosols in Shanghai were quantified with GC-MS. The concentration of PAHs in winter was highest, and summer lowest. Most of PAHs were found on aerosol particles having aerodynamic diameter between 0.43 and 2.1 μm. The three- four- and five-ring PAHs were appeared the unimodal distribution form for the highest concentration in 0.43—1.1 μm size range was found.
