| 摘 要： | 运用大气挥发性有机物(VOCs)快速在线连续自动监测系统,于2018年7月对南通市区环境空气中VOCs进行观测,分析VOCs的浓度状况、组成特征、对臭氧生成潜势的贡献及主要来源。结果表明:观测期间共检出100种VOCs,总挥发性有机物(TVOCs)的平均体积分数为(38. 18±23. 63)×10^-9,各物种体积分数从大到小顺序依次为烷烃>含氧有机物>芳香烃>卤代烃>烯、炔烃;芳烃和烯烃是最主要的活性物种,间/对二甲苯、甲苯、邻二甲苯等是VOCs的关键活性组分;利用PMF模型解析得到VOCs的主要污染来源是工业排放与溶剂使用、机动车尾气排放、燃料挥发排放和生物源排放。

| Abstract: | The concentration,speciation,source and the contribution to ozone formation potential of VOCs in Nantong were analyzed and measured using online gas detection systems in July 2018. The results showed that the averaged volume fraction of TVOCs was (38. 18 ± 23. 63) × 10^-9,and the order of volume fraction of each species VOCs was alkane > oxygen-containing VOCs > aromatics > Halogenated hydrocarbons > alkene and alkyne. Aromatics and alkenes were the most active components in ambient air,including m/p-xylene,toluene,o-xylene,etc. The VOCs pollutants were mainly contributed by industrial emissions and solvent use,motor vehicle exhaust,fuel volatilization and biogenic emissions using PMF model. |
