沈阳市环境空气总悬浮颗粒物的污染及其防治

Pollution and Control of Total Suspended Particulate in Ambient Air in Shenyang

以沈阳市环境监测中心站１９９０～１９９７年８年的监测结果为基础，阐述了沈阳市环境空气总悬浮颗粒物的污染状况、时空分布及总悬浮颗粒物中粒径小于１０μｍ的飘尘污染状况．并用秩次相关检验法分析了总悬浮颗粒物的污染趋势，结果显示，８年的总悬浮颗粒物年均值均超标，尤以冬季和工业区污染最为严重，８年的污染状况变化不显著．最后分析了总悬浮颗粒物的污染原因，提出了相应的防治措施．

On the basis of the data from 1990 to 1997 which were determined by Shenyang Environmental Monitoring Central Station, the pollution state of total suspended particulate (TSP) and its distribution of time and space, and the inhalant particulate (IP) in ambient air in Shenyang were discussed. The pollution tendency of TSP was analyzed. It is indicated that mean annual value of TSP exceeded the standard in all 8 years, especially that in winter and industral area were more higher. The change of pollution in 8 years is not significant. The pollution resource of TSP is investigated and the control methods are presented.
