Abstract: In order to understand the characteristics of ozone pollution and volatile organic compounds in an electronic information industry area in summer, the ozone pollution process and the characteristic components of VOCs were analyzed combined with data, and the source of VOCs was analyzed. A total of 94 compounds were detected in this study, and the concentration order of various VOCs is alkanes > halogenated hydrocarbons > aromatic hydrocarbons > OVOCs > olefins > alkynes. According to the analysis of ozone generation potential, the overall concentration level of ozone is obviously related to the ozone generation potential of VOCs and weather factors. Select the period of high ozone value to analyze the ozone pollution process in combination with nitrogen oxides, PM_2.5 and VOCs. Ozone shows a regular unimodal change, which is opposite to NO_x and PM_2.5. The source analysis results of PMF model show that during the high ozone value period, the industrial emission source dominated by benzene homologues has the highest contribution rate to ozone generation in the industrial area.
Keywords: electronic information industry zone;ozone;volatile organic compounds(VOCs);source analysis
