抚顺市TSP中的金属元素分布特征

分析了抚顺市区5个监测点位,2002年1月和7月TSP样品中10种金属元素的含量.结果表明:抚顺市的5个大气例行点位中,只有清洁对照区达到国家二级标准,而望化、新华、东洲、站前4个点位均超过国家二级标准,说明抚顺市的颗粒物污染严重,空气质量不容乐观.市区各功能区之间元素分布特征有明显差异,望化区的TSP样品中重金属含量明显高于其它4个点位;通过富集因子分析显示:Cu、Cr、Zn、Pb主要来源于人为污染.

Research on Distribution Characteristic of Heavy Metal in Total Suspended Particle in Fushun

This paper analyzes the amount of ten metal elements in TSP samples of fire inspection spots in urban Fushun between January and July in 2002.The result shous that among the fire inspection spots in Fushun,only sanitary comparison area has reached national level 2 standard,nhile four spots like Wanghua,Xinhua,Dongzhou and Zhanqian hare exceeded level 2 standard.This shows that the apportionment of Dust pollntion of Fushun is very serious and the atmosphere quality is not optimistic.There exists distinct difference in element location features of different function areas of the city.The amount of heary metal elements of TSP sample in Wanghua District is obviously higner than other four spots.Through enrichment factors analysis:Cu,Cr,Zn and Pb mainly originate from human pollution.
