摘　　要：以株洲市2018年SO2、NO2、CO、O3、PM2.5和PM10六项污染物质量浓度数据为基础,分析了株洲市污染物的浓度水平和特征,并对雾霾天气进行研究。结果表明,PM2.5和PM10年均浓度分别为45μg/m^3和71μg/m^3,未达到国家二级标准限值。O3、PM2.5和PM10均发现日均值超标现象。株洲市大气污染季节性特征明显,5-10月以O3污染为主,而其余月份以颗粒物污染为主。雾霾天气中PM2.5/PM10为0.78,较年平均值高。The mass concentration data of SO2,NO2,CO,O3,PM2.5and PM10in Zhuzhou City in 2018 were collected to analyze the concentration level and characteristics of pollutants.The characteristics of haze weather were also studied.The results showed that the average annual concentrations of PM2.5and PM10were 45μg/m^3 and 71μg/m^3,respectively,which didn’t reach the national second-class standard limit.The daily average concentrations of O3,PM2.5and PM10were founded to exceed the standard.The seasonal characteristics of air pollution were obvious.O3was the main pollutant between May and October,while particulate pollution was the main pollution in the rest of the month.The PM2.5/PM10in the haze weather was 0.78,which was higher than the annual average.
