外文摘要：Ozone (O-3) and particulate matter (PM2.5) pollution are major pollution problems faced by global cities. Volatile organic compounds (VOCs) are common precursors of O-3 and PM2.5. In this study, the concentration and composition characteristics of target volatile organic compounds (VOCs) were monitored at five sampling points distributed in the industrial zone of Shaoxing city, Zhejiang Province, China. The source of VOCs, O-3 and PM2.5 was analyzed by the positive definite matrix factor analysis software (PMF) developed by the U.S. Environmental Protection Agency. The results show that VOCs in industrial zones mainly come from four sources: oil and gas volatile sources (50%), motor vehicle emission sources (22%), organic solvent sources (18%), and photochemical or biological sources (10%). The analysis results of O-3 sources show that the share of ozone formation potential (OFP) of each emission source is as follows: oil and gas volatile source (43.4%), motor vehicle emission source (25.5%), organic solvent source (20.1%) and photochemical or biological source (11%). PM2.5 mainly comes from four sources: secondary inorganic salt source (44%), motor vehicle emission source (23%), industrial source (20%) and dust source (2%). The results and interpretation of this study provide information for the formulation of effective ozone and related stethoscope control measures in micro-industrial cities in the Yangtze River Delta of China.
