省环保厅发布14个城市8月份环境空气质量排名情况

2017-09-08 05:11:50   中国青年网

省环保厅今日向媒体发布了14个城市2017年8月份环境空气质量排名情况。

8月份,全省14个城市环境空气质量综合排名由好到差分别为张掖、陇南、金昌、甘南、临夏、天水、定西、平凉、庆阳、武威、嘉峪关、酒泉、白银、兰州。除白银、武威、兰州外,省内其他城市环境空气质量均优于去年同期。

省环保厅有关负责人介绍,8月份,全省14个城市PM10月均浓度值为44微克/立方米,同比下降12.0%。11个城市同比下降,其中临夏、甘南、天水、定西等地降幅在20%以上;2个城市同比上升,白银上升23.4%,武威上升19.6%;酒泉同比持平。

1—8月份,全省14个城市PM10平均浓度值为73微克/立方米,同比下降3.9%。张掖等8个城市同比下降,降幅在1.2%—27.8%之间;甘南、庆阳、天水、陇南、兰州、白银等6个城市同比上升,升幅分别为14.1%、13.8%、12.3%、5.9%、5.0%、3.7%。

据分析,8月份,全省雨水较多,污染物扩散条件有利,防治措施不断强化,空气质量总体改善,但形势依然严峻,任务十分艰巨。离冬季供暖期不足两个月,解决燃煤散烧问题,加大煤质管控力度,加快燃煤锅炉综合整治,应作为目前工作重点。

说明:1.环境空气质量综合指数排名越靠前,该地区环境空气质量越好。2.环境空气质量综合指数同比变化率绝对值越大,空气质量变化程度越大。若为正值,表明该地区环境空气质量较去年同期差;若为负值,则优于去年同期。
