　　合肥空气昨现重度污染(图)

　　十个监测子站均为重度污染；秸秆焚烧和气象条件所致

　　昨天，合肥又被蒙上了一层灰蒙蒙的“薄纱”。新安晚报记者观察合肥市空气质量监测系统发现，从昨天上午10点开始，直到下午5点，十个监测子站均一直呈现“重度污染”状态，首要污染物均为PM2.5。

　　昨天10点至15点，合肥各个监测子站的每小时PM2.5污染浓度均在150微克/立方米以上，24小时平均浓度也是如此，已是国家二级标准浓度限值的2倍。直到下午四五点，PM2.5的实时浓度才有所下降，不过，各个子站仍然呈重度污染。

　　合肥市环保局相关负责人告诉记者，造成这种空气状况的原因非常复杂，近期来看秸秆烟是祸首。同时，气象也是一个重要原因，阴雨天将至，气压低，空气流动缓慢，导致污染物的扩散条件非常差。

　　记者从环保部门了解到，28日的卫星过境监测记录显示，安徽发现9个火点(不包括云覆盖下的火点信息)，为当天“全国最高”。9个火点分别位于安庆市(5个)、蚌埠市(2个)、滁州市(1个)以及六安市(1个)。

　　合肥市农委能源办工作人员告诉记者，合肥地区的秋种已经收尾，空气中的烟味很可能不是来自合肥。这一说法，也得到了环保部门的认同，据相关工作人员介绍，焚烧秸秆产生的烟雾能被大气远距离传输。
