| 摘 要： | 分析了荆州市大气颗粒物粒径的分布特征和化学元素组成特征.结果表明,荆州市存在一定程度的颗粒物污染;5个采样点的污染程度依次为:沙市热电厂＞沙隆达广场＞荆州东门＞长江大学西校区＞荆州郢都自来水厂;可吸入颗粒物(PM10)和总悬浮颗粒物(TSP)存在确定数量关系,两者有极好的相关性; PM10在TSP中的分担率为41.7%～65.4%;土壤风沙尘对TSP的贡献较大,机动车尾气尘和煤烟尘对PM10的贡献较大.

| Abstract: | The distribution characteristics of grain-size and chemical element characteristic of atmospheric particulate matter in Jingzhou were studied. The results indicated that a certain degree of particle pollution existed in Jing-zhou; The pollution degree of 5 pieces of sampled point is successively: Heat and Power Plant of Shashi >Shalongda Plaza >East door of Jingzhou > The western section of Yangtze University>Yingdu Waterworks of Jingzhou; There was a definite quantitative relation between inhalable particles (PM_ 10 ) and the total suspended particulate substance (TSP ) , and extremely good dependence; The sharing rate of PM_ 10 in TSP is 41.7%~65.4%; Soil sand blown by the wind dust contributed relatively heavy to TSP and motor vehicle tail gas and dust of soot contributed to PM_ 10to a greater extent. |
