典型非石化城市大气中挥性有机物VOCS污染特征研究

AbstractVOCs (volatile organic compounds)is a kind of air pollutants in the form of gas,which has a serious impact on human health and the environment.With the complexchanges of China's economy and development situation,the environmental problemsare becoming more and more complex.In recent years,the VOCs emissions areincreasing,and the chemical composition of VOCs is relatively complex,and thegovernance process is relatively complicated,which has attracted people's attention.At present,the prevention and control of VOC pollution has become one of theimportant tasks of environmental governance.The study on the composition andcharacteristics of VOCs can provide important reference for the study of VOCssources,pollution characteristics and control strategies.This paper takes a typical non petrochemical city as the research area,Based on72 VOCs species monitored from2019 in winter,the pollution characteristics of VOCsin non Petrochemical cities and the source analysis of VOCs in the atmosphere arestudied.In this paper,the receptor model method is used to analyze the sourceanalysis results of VOCs and compare them with other cities.Combined with theVOCs data monitored,the VOCs emission characteristics and composition spectrumcharacteristics are listed.The pollution control measures of VOCs in typical nonPetrochemical cities are put forward.Key words:VOCs,VOCs species composition,activation analysis.
