年度空气质量AQI展示
2020年,市区环境空气中细颗粒物(PM2.5)浓度为31μg/m3,同比降低16.2%;可吸入颗粒物(PM10)浓度为61μg/m3,同比降低17.6%;二氧化硫(SO2)浓度为7μg/m3,同比降低12.5%;二氧化氮(NO2)浓度为31μg/m3,同比降低3.1%;臭氧(O3)浓度为145μg/m3,同比降低1.4%;一氧化碳(CO)浓度为1.2mg/m3,同比降低20.0%。六项污染物浓度均达标,为《环境空气质量标准》(GB3095-2012)实施以来首次全面达标。PM2.5、PM10、SO2、NO2、CO浓度均为《环境空气质量标准》(GB3095-2012)实施以来最低水平。市区空气质量优良率86.3%,排名全省第二。SO2、O3、PM2.5、PM10、CO浓度分别列全省第2、2、3、3、3位,均处于全省前列。全年共出现重度污染天3天,其中1月份2天,12月份1天,未出现严重污染天,与2018年同为《环境空气质量标准》(GB3095-2012)实施以来重污染天最少的年份。与2019年相比,重度污染天数减少4天。
