2004年郑州市不同区域大气污染现状分析

目的 分析郑州市大气污染的原因,提出大气污染防治对策。方法把2004年郑州市不同区域大气监测数据换算成环境质量指数从而进行评价。结果郑州市居民区内空气质量为三级,除了河医大监测点首要污染物为二氧化硫外,其它监测点首要污染物均为可吸入颗粒物。代表居民区的河医大、烟厂监测点综合污染指数最高,大于代表工业区的郑纺机、监测站综合污染指数。结论郑州工业区、居民区混杂,工业布局不合理是造成大气污染的重要原因,建议发展生态工业和循环经济、加强生态城市规划。

The Analysis of the Current Air Pollution in Zhengzhou Area in 2004

Objiective Investigating the cause of air pollution in Zhengzhou city and suggesting the strategies to deal with it.Methods Assessing the air quality by converting into the Air Pollution Index the monitoring data from different regions of Zhengzhou Area in 2004.Results The air quality of residence zones,in Zhengzhou city,just reached the tertiary standard in GB3095-1996.In 2004,the primary source of air pollutants came from inhalational particles(PM10) in all monitoring sites except for Henan University of Medical Science in which site it is SO2.The Comprehensive Air Pollution Index of Henan University of Medical Science and the factory of cigarette,the representatives of residence zones,in Zhengzhou city,are higher than those of the factory of textile machinery and the monitoring station,the representatives of industrial areas.Conclusion The mixture of residence zones and industrial areas,and the unadvisable layout of industries are the main reasons for the air pollution.It is suggested to develop the ecology industry and the circling economy,and build up the planning of ecology city.
