摘要通过收集各类VOCs排放源的活动水平数据,选择合适的排放因子,利用排放因子法建立了2021年南京市VOCs人为源排放清单.并通过筛选合适的VOCs源成分谱,建立了南京市VOCs物种排放清单,分析了南京市各排放源以及不同VOCs组分的排放特征.结果表明,2021年南京市排放VOCs约302.85kt,其中工艺过程源的排放量最高(182.94kt),占比可达60.41%,其次为道路移动源(19.46%),非道路移动源占比最少(0.40%).在VOCs物种清单中,排放量最多的为烷烃(109.06kt),其次是卤代烃(75.08kt)和芳香烃(50.72kt).排放量贡献前10的物种分别为:氯乙烯、乙烷、丙烷、三氯乙烯、1,2-二氯乙烷、对二甲苯、正丁烷、乙苯、其他烷烃和乙烯,占总量的63.96%,主要来自合成纤维单体制造和原油加工行业.

Abstract：Based on emission factor method, the Volatile Organic Compounds (VOCs) emission inventory of Nanjing was established in 2021 using the activity data of various VOCs emission sources, emission factors and source profiles of VOCs. VOCs emissions for each source and different VOCs source profiles in Nanjing were analyzed. The total amount of VOCs emissions in Nanjing in 2021 was about 302.85kt. Industrial process sources were the major source of total VOCs emissions accounting for 60.41% (182.94kt), followed by on-road mobile sources (19.46%). The least emission contribution was from off-road mobile sources (0.40%). The highest emission for VOCs species inventory come from alkanes (109.06kt), followed by halogenated hydrocarbon (75.08kt) and aromatic hydrocarbon emissions (50.72kt). The top ten species contributing to emissions were vinyl chloride, ethane, propane, trichloroethylene, 1,2-dichloroethane, p-xylene, n-butane, ethylbenzene, other alkanes and ethylene, respectively. The emissions of top ten species accounted for 63.96% of the total emissions, which mainly from synthetic fiber monomer manufacturing and crude oil processing.
