| Abstract: | This study focused on the characterization and the health risk assessment of heavy metals in the dust of Hefei City,China.Samples were collected from fifty two sampling points covering six land-use types.Most of the sites were impervious ground such as residential,commercial,industrial,educational and traffic areas,as well as public landscapes and city squares.Concentrations of Zn,Pb,Cu,Cd and Cr were measured to investigate their distribution and evaluate their risk to human health.The US EPA Health Risk A... |
