2012年和2014年,武汉同一时间、因同样原因遭遇雾霾袭城,能见度不足3公里。武汉市环境空气质量实时发布系统显示,2014年,武汉市9个监测点中,PM2.5、PM10均已超过500微克/立方米。PM2.5最近1小时均值最高的监测点东湖高新监测点达到895微克/立方米。监测结果显示,PM2.5和PM10等颗粒物中,有机碳、元素碳以及钾离子的监测值均显著上升。环保部秸秆焚烧遥感监测图也显示,安徽、河南、陕西、江西四省份存在122个着火点(其中安徽96处,河南24处),均为秸秆焚烧。大面积焚烧的
In 2012 and 2014, at the same time in Wuhan, haze hit the city for the same reason, visibility was less than 3 km. The real-time release system of ambient air quality in Wuhan showed that in 2014, among the 9 monitoring sites in Wuhan, PM2.5 and PM10 exceeded 500 micrograms per cubic meter. PM2.5 Highest 1 hour mean monitoring point East Lake high-tech monitoring point to 895 micrograms / cubic meter. The monitoring results showed that the monitoring values of organic carbon, elemental carbon and potassium ions in PM2.5 and PM10 increased significantly. Ministry of Environmental Protection straw burning remote sensing monitoring map also shows that there are 122 fire points in Anhui, Henan, Shaanxi and Jiangxi provinces (of which 96 in Anhui, Henan 24), are straw burning.
