摘　　要：为研究郑州市高新技术产业开发区(以下简称“高新区”)环境空气挥发性有机物(VOCs)污染的特征、光化学反应活性和来源,采用手工采样的方式,环境空气样品通过苏玛罐采集后,经气相色谱分离FID/MS检测器进行分析,利用正交矩阵因子模型(PMF)解析数据结果来源。分析结果表明芳香烃类化合物对平均臭氧生成潜势(OFP)和气溶胶生成潜势(AFP)的贡献均为最高,VOCs主要来源为工业排放源、油气挥发源、溶剂使用源、燃烧排放源、机动车排放源,占比分别为27.4%、23.5%、22.6%、15.7%和10.8%。因此,郑州市高新区应进行工业排放源,油气排放源和溶剂排放源的减排,并重点关注芳香烃类VOCs的排放。In order to study the characteristics,photochemical activity,and sources of atmospheric volatile organic compounds(VOCs)pollution in high-tech development Zone of Zhengzhou,samples were collected by manual,using summa canisters,and the samples were separated by gas chromatography,then analyzed by FID/MS detector.The source apportionment was analyzed by the positive matrix factorization(PMF)model.The results showed that the aromatics accounted have the highest contribution to the average ozone generation potential(OFP)and aerosol generation potential(AFP).The results showed that aromatic hydrocarbons had the highest contribution to the average ozone generation potential(OFP)and aerosol generation potential(AFP).The main sources of VOCs in Zhengzhou High-tech Zone were industrial emission sources,oil and gas volatile sources,solvent use sources,combustion emission sources,and motor vehicle emission sources,which account for 27.4%,23.5%,22.6%,15.7%,and 10.8%,respectively.Therefore,Zhengzhou High-tech Zone should carry out the emission reduction of industrial emission sources,oil and gas emission sources and solvent emission sources,and focus on the emission of aromatic hydrocarbon VOCs.
