摘　　要：酞酸酯对人体健康极其有害.对北京市夏季大气中酞酸酯类污染物进行了定性定量分析,检测到酞酸酯类污染物共15种.其中一些属于美国国家环保局(EPA)优先控制的环境激素类污染物.其主要来源于塑料和树脂工业中广泛使用的增塑剂,也有相当部分来源于工业燃料的燃烧.从本次所测定的几种典型酞酸酯类的含量即可发现,北京市经过几年大力整治,2005年大气中的酞酸酯类污染物含量比2001年有所降低.15 kinds of phthalic of the phthalic esters were relatively esters were detected in the aerosol in summer at Beijing. The total content higher Some phthalic esters are precedent - controlled harmful pollutants to the Environmental Protection Agency （EPA）. They mainly come from plasticizer in plastics and resins, and also partly come from burning of industrial fuel. The detection result shows that the content of DBP in 2005 become lower than that in 2001, but it still higher than other cities. These phthalic esters pollutants are rather toxic to human health and should be taken more considerations.
