摘要
采用盱眙县环境监测站2014年1—12月PM10、PM2.5、SO2、NO2、O3逐日质量浓度资料及盱眙国家基本气象站同期气象资料,分析不同气象条件下盱眙县空气质量变化。结果表明：盱眙县主要污染物是PM2.5、PM10,污染较轻的是SO2、NO2、O3;盱眙县空气质量变化趋势为春冬季污染严重,夏秋季污染较轻。气象条件中的降水因子对改善空气质量、清除颗粒物具有明显作用;当温度在0℃以下或30℃以上时空气质量相对较好,0-20℃时空气污染情况较为严重;偏东风时大气环境质量较差,偏北风时大气环境质量较好。
Based on the PM10, PM2.5, SO2, NO2 and O3 concentration data from the Xuyi county envi- ronmental monitoring station and the meteorological data from Xuyi station meteorological data from January to December of 2014, the air quality change under different meteorological conditions in Xuyi County is analyzed.The results show that the main pollutants in Xuyi county is PM2.5 and PM10while SO2 and NO2 pollution is light.Air pollution is more serious in spring and winter while it is not so severe in summer and autumn.Precipitation can improve air quality and remove air pollutants obviously. The air quality is better when the temperature is higher than 30 ℃ or lower than 0 ℃ while it is worse when the temperature is between 0 ℃ and 20 ℃. Moreover, the air quality is worse when the wind comes from east while it gets better when the wind comes from north.
