摘要
上海市吴泾工业区应用自动监测系统对挥发性有机物(VOCs)进行了监测分析,并根据监测浓度数据进行了来源解析。结果表明,52种VOCs成分良好分离,全部实现准确定性。其中,浓度偏高而危害较大的16种有机物,浓度都高于2μg/L。对VOCs成分的来源解析,分析了空气流动、汽车尾气、燃料挥发、涂料使用、石油化工这5种来源。同时,通过对氮氧化物、臭氧的浓度日变化的监测,间接说明吴泾工业区作为VOCs控制区的这5种可能来源,从而印证了VOCs的监测分析。
Automated monitoring system for volatile organic compounds(VOCs) in Shanghai Wujing Industrial Zone has been applied. According to the monitored concentration datas, source apportionment of VOCs has been analyzed. Results showed that, 52 kinds of VOCs were well separated, while concentrations of 16 kinds were higher than 2 μg/L. Source apportionment of VOCs reflected five sources, such as air flow, vehicle exhaust, fuel evaporation, paint application and oil chemical industry. Then, through the monitoring of nitrogen oxides and ozone, the five sources were indirectly illustrated, which con-firmed the monitoring analysis of VOCs.
