中文摘要 基于本地污染源调查，同时对重点工业行业进行实地采样测试，建立了郑州市高新区工业VOCs排放清单及组分清单，并评估了VOCs各组分的臭氧生成潜势（OFP）和二次有机气溶胶生成潜势（SOAp）.结果表明，2017年郑州市高新区工业源VOCs排放总量为4566.0 t，橡胶和塑料制品业、设备制造业和有色金属业是排放量最大的3个行业，排放量分别为1924.2、1396.3和813.4 t；各VOCs组分中，烷烃占比最大（40.9%），其次是含氧VOCs（32.2%）和芳香烃（20.3%）；异丙醇、正十二烷、甲苯、甲基环己烷和丙酮是排放量最大的5种物质；OFP总量为8753.8 t，最大贡献源和VOCs种类分别为设备制造业和芳香烃；SOAp总量为643.0 t，贡献较大的排放源为设备制造业和铝箔制造业，烷烃和芳香烃是两种主要贡献组分. 英文摘要 In this study, based on the data of industrial sources obtained from a field survey and conducting field sampling tests on the key industrial industries in Zhengzhou High-tech Zone,an industrial emission inventory of volatile organic compounds (VOCs) and a VOC speciation emission inventory were established. We also evaluated the ozone formation potential (OFP) and secondary organic aerosol formation potential (SOAp) of each component of the VOCs. The results showed that the total industrial VOC emissions of Zhengzhou High-tech Zone in 2017 was 4566.0 t, and the rubber and plastic products industry, non-ferrous metal industry, and equipment manufacturing industry were the top three industries, with emissions of 1924.2, 1396.3, and 813.4 t, respectively. Among the VOC components, alkanes accounted for the largest proportion (40.9%), followed by oxygenated VOCs (32.2%), and aromatic hydrocarbons (20.3%). The five substances with the largest emissions were isopropanol, n-dodecane, toluene, methylcyclohexane, and acetone. The total amount of OFP was 8753.8 t, and the largest contributing source was the equipment manufacturing industry; the largest VOC species present was aromatic hydrocarbons. The total amount of SOAp was 643.0 t. Additionally, the largest emission sources were the equipment manufacturing industry and aluminum foil manufacturing industry; the alkanes and aromatic hydrocarbons were the two main contributing components.
