摘要
2007年秋季在淮南市五个采样点采集大气可吸入颗粒物样品,用色谱-质谱法分析多环芳烃中16种优控污染物。结果显示,交通区PAHs浓度最高;PAHs以四环为主,二环所占比例最小;PM10与ΣPAHs成显著正相关关系,与苯并[a]芘成显著正相关;采用比值法对淮南市PM10中的PAHs进行来源分析,得到PAHs主要来源于交通源及燃煤排放。
In the autumn of 2007, sampled the PM10 at the five sampling sites in Huainan city, used the GC - MS to analyze the EPA 16 priority polycyclic aromatic hydrocarbons. The results showed that, the PAHs concentration was maximal at the traffic area. PAHs were mainly four loops; the ratio of 2 loops was the least. The relationship between PM10 and PAHs was notable positive correlation, PM10 and BaP was highly notable positive correlation. This paper used the ratio method to analyze the resources of PAHs, got the result that the PAHs mainly came from the traffic resource and the coal burning resource.
