中文摘要：

采用气相色谱-质谱分析了2013年杭州市下沙与朝晖夏秋冬三季的大气细颗粒物中邻苯二甲酸二丁酯（DBP）、邻苯二甲酸二乙基己酯（DEHP）、邻苯二甲酸二辛基酯（DOP）、邻苯二甲酸苄基丁基酯（BBP）4种PAEs的污染状况及可能的来源.结果表明：大气PM2.5中PAEs污染以DBP和DEHP为主,工业区PAEs质量浓度明显高于生活区,且冬季质量浓度明显高于夏秋两季.根据两地的污染情况分析,下沙工业区大气细颗粒物中PAEs污染主要来自于工业污染源和喷漆涂料,朝晖居民区大气PM2.5中PAEs污染主要来源于塑料垃圾及喷漆涂料.

英文摘要：

The pollution situation of phthalate esters （PAEs） with seasonal variation were analyzed in this paper by characterizing the concentration changes of dibutyl phthalate（DBP）,Di- 2 ethylhexyl phthalate（DEHP）, di-n-octyl phthalate（DNOP）and benzyl butyl phthalate（BBP） in PM2. 5 particles in summer, autumn and winter respectively in 2013, Hangzhou using GC MS. At the same time, we explored the possible sources of the mentioned PAEs. The results showed that the main atmospheric pollutants of PAEs were DBP and DEHP in Hangzhou. The concentration of PAEs in the industrial area was significantly higher than that in the living area, and the concentration of PAEs in winter was obviously higher than that in summer and autumn. The contaminant of PAEs in PM2.5 particles of Xiasha industrial Zone was mainly caused by industrial pollution and paint spraying, and the pollution of PAEs in Zhaohui living area was mainly attributed to plastic waste and paint coatings.
