【摘要】 通过对淄博市某区域6个月来6个点位大气降尘中重金属监测分析,结果显示淄博市某区域大气降尘受重金属污染比较严重。大气降尘中6中重金属含量范围依次为Cd 0.21～0.39 mg/kg,Cu 115～169 mg/kg,Ni 61.8～124 mg/kg,Pb 333～535mg/kg,Cr 117～258mg/kg,Zn 685～1820 mg/kg。Cd、Cu、Ni、Pb、Cr、Zn等6种主要重金属元素均超出当地土壤中重金属调查含量平均值,而且工业区的污染高于生活区。更多还原

【Abstract】 Heavy metal samples that were collected at six spot positions of a certain district in Zibo for six month have been anlysed.The results showed that heavy metal pollution of dustfall is very danger.The concentration of Cd in dustfall ranged from 0.21 to 0.39mg/kg,Cu 115~ 169mg/kg,Ni 61.8~124 mg/kg,Pb 333~535mg/kg,Cr 117~258mg/kg,Zn 685~1820mg/kg.The content of Cd,Cr,Cu,Ni,Pb and Zn are higher than that mean of local soil background.At the same time,comparing with housing district,the content of heavy metal in dustrial district is higher than that of housing district.更多还原
