【摘要】 借助苔藓植物,应用大气净度指数(index of atmospheric purity)法与重金属(Mn、Fe、Cu、Cr和Pb)含量化学分析法相结合指示沈阳市的大气质量状况。结果表明:沈阳市样点可根据大气污染状况划分为3个区域,其中市区污染程度大于郊区,市区西部污染大于东部,南部大于北部;各区以Pb污染程度最为严重,值得重视。该结果与监测站所得空气污染指数(air pollution index)结果相符。更多还原

【Abstract】 With the combination of the index of atmospheric purity(IAP)and the chemical analysis of heavy metals(Mn,Fe,Cu,Cr and Pb)contents in mosses,the air quality in Shenyang City was evaluated.According to the air quality,Shenyang City could be divided into three regions,among which,urban area had a far worse air quality than rural area,and the western urban area was worse than the eastern area,and southern urban area was worse than the northern area.In all the regions,Pb-pollution was most serious,and should be taken attention.The results mentioned above were consistent with the air pollution index(API)obtained by monitoring stations.更多还原
