赤峰市取暖期环境空气质量评价

目前整个北方地区的供暖主要依靠燃煤,而且不少地方使用劣质煤更是加重了供暖期的污染状况。文章对2015-2017年取暖期赤峰市环境空气质量状况进行评价分析。结果表明,2015-2017年赤峰市取暖期首要污染物为PM2.5,SO2和CO月均浓度1-4月份持续下降,10-12月份持续上升;O3月均浓度1-4月份持续上升,10-12月份持续下降。NO2、PM2.5和PM10月均浓度均有小幅波动。2015年和2016年污染指数最高值均出现在12月份,2017年出现在1月份。

At present,the heating of the whole northern region mainly depends on coal burning,and the use of inferior coal inmany places has aggravated the pollution situation during the heating period. This paper evaluates and analyzes the environmental airquality of Chifeng City during the heating period from 2015 to 2017. The results showed that the primary pollutants in the heatingperiod of Chifeng city in 2015-2017 were the decrease of PM2.5,SO2 and CO concentrations from January to April,the increasefrom October to December,the increase from January to April,and the decrease from October to December. The monthly mean con-centrations of NO2,PM2.5 and PM10 all fluctuated slightly. Both 2015 and 2016 saw their highest levels in December,and 2017 inJanuary.
