| 摘 要： | 选取河南省某市31个幼儿园采集地表灰尘样品,用火焰原子吸收分光光度法测定其Zn、Pb、Cr、Cu和Ni含量,应用地积累指数法和潜在生态风险指数法探讨了灰尘重金属的污染特征和潜在生态风险.结果表明:城区幼儿园灰尘Zn、Pb、Cr、Cu和Ni的平均含量分别是郊区对照幼儿园的1.93、2.13、5.45、1.90和0.98倍...

| Abstract: | Many studies have been undertaken on heavy metal pollution of surface dust or street dust in many cities,but very few studies have been done on the pollution and potential ecological risk of kindergarten dust.Thirty-one surface dust samples were collected from kindergartens in one of cities located in the east of Henan Province,China.Concentrations of Pb,Zn,Cr,Cu and Ni in the samples were determined using F-AAS(flame atomic absorption spectrophotometry).Pollution and potential ecological risk of heavy meta... |
