济南市市区大气颗粒物污染来源研究

[目的 ]确定济南市市区大气污染的首要污染物———颗粒物 (总悬浮颗粒物TSP及可吸入颗粒物PM1 0 )的主要来源 ,为环境管理及治理提供技术支持。[方法 ] 1 999年 1 2月至 2 0 0 0年 9月在济南市市区及其周围设点采集空气中各种排放源颗粒物 ,并运用化学质量平衡 (CMB)模型确定不同排放源的分担率。 [结果 ]济南市市区大气颗粒物主要来源于扬尘、煤烟尘和风沙尘 ,对TSP及PM1 0 的分担率分别为 34%和 30 % ,2 5 %和 1 9% ,1 8%和 2 2 %。 [结论 ]济南市市区煤烟尘污染得到了有效控制 ,扬尘污染与机动车的污染仍然严重

A Study on Sources of Atmosphere Granule Pollution in Urban Districts of Jinan City

Objective]To determine the main source of granule,the leading pollutant of atmosphere pollution in Jinan urban districts,and provide technical support for environment management and treatment The granules from all sources were sampled in urban Jinan and surrounding areas between December 1999 and September 2000,and the rate of contribution and participation was determined by CMB model The main sources of granules were the dust blown by wind, fulunigio and sand blown by wind, the three kinds of dust accounted for 34% and 30% ,25% and 19%,18% and 22% respectively in the quantity of TSP and PM 10 [Conclusions]The soot pollution is controlled effectively, but pollution of the dust blown by wind is serious and automobile exhaust pollution is rising
