摘要
采用毛细管气相色谱—质谱联用技术(GC/MS),结合溶剂提取和柱色层分离方法,系统地分析了上海市大气颗粒物样品中有机污染物的化学组成,共检出302种有机化合物,采用时间分辨激光诱导荧光技术测定了13个采样点的夏季和冬季各样品中苯并(a)芘的含量,全市年平均值为7.1ng/m^3。
The organic pollutants in airborne particulates in Shanghai have been investigated by using GC/MS, coupled with solvent extraction and silicagel column chromatographic separation techniques. It was found that there are 302 kinds of organic compounds in the airborne particulates. The content of benezo(a)pyrene at 13 different sites were also determined by time-resolved laser induced fluorescence method, and the average amount of this compound in this year was 7.1μg/1000m3.
