Correlation Between PAMS Concentration And Atmospheric Ozone Concentration In A Chemical Industry Park In Taizhou City

With the accelerated development of urbanization and industrialization,O3 pollution has become a common and difficult problem of secondary pollution[1-4].In Taizhou City,O3 is the primary pollutant in environmental air,and its high incidence period is mainly concentrated from May to October,and O3 pollution is more pronounced in some areas.In this context,in order to solve the problem of O3 pollution from the source,this study combines the monitoring data of a chemical industrial park in Taizhou City in 2021,and studies the correlation between PAMS concentration in Taizhou City chemical park and atmospheric O3 concentration.The following conclusions were drawn:(1)The study found that due to the relatively intensive chemical industry,there is a fluctuating trend in O3 concentration in the Taizhou City chemical park.The study shows that differences in meteorological factors and precursor substances lead to significant differences in O3 concentration during non-heavy pollution and heavy pollution periods.In addition,with changes in temperature and climate,O3 pollution is most severe from June to July.There is a significant correlation between the accumulation of O3 concentration and climate change.In the period of heavy O3 pollution,higher temperature,and lower humidity lead to higher concentration of pollutants,thereby making it easier to accumulate O3 pollutants.(2)Olefins and alkanes are the main components generated by O3 in the Taizhou Chemical Industry Park,and their contributions to PEC and OFP are higher than other components,with olefins>alkanes>aromatic hydrocarbons.In addition,propylene,isopentane,and toluene are the species that contribute the most to O3 generation.The production emissions and transportation conditions within the park may create convenience for the accumulation of O3.(3)Combining the research results within the park,a variety of measures to control atmospheric O3 pollution within the park are proposed from the aspects of implementing environmental protection concepts,resolutely executing policies,scientifically adjusting production,seasonal emission control,and improving monitoring networks,which will help achieve coordinated development.
