晋城市大气中有机污染物的分析

ANALYSIS OF ATMOSPHERCE ORGANIC POLLUTANTS IN JINCHENG AMBIENT AIR

对晋城市大气中气相和颗粒物上的有机污染物进行了分析研究,并测定了总悬浮颗粒上(TSP)二氯甲烷萃取物的总量,TSP上有机物的含量为7%～13%,平均7.3±3.1%。用GC/MS和HPLC鉴定出气相中的主要污染物49种;颗粒物上的主要污染物60多种。这些污染物的种类和数量都是采暖期高于非采暖期。

The organic pollutants in both vapor and particulate phases from the total suspended partieuletes(TSP) in Jincheng ambient air were studied. The extracts in methylene chloride representing the total polluted organic materials account for about 7%～13 %, (mean 7.3±3.1%). The analysis of organic pollutants were performed using GC, GC/MS and HPLC. The 49 compounds in vapor phases and about 60 compounds in TSP were identified. The kind of these compounds and concentration in the heating season were higher than in the nonheating season.
