Toxic and Trace Metals(Pb,Cd,Zn,Cu,Mn,Ni,Co and Cr)in Dust,Dustfall/Soil

摘要

Metals(Pb,Cd,Zn,Cu,Mn,Ni,Co and Cr etc)emitted into the urban air from different sources(coal and petroleum burning,municipal incinerators,automobile exhaust,refuse burning,pesticide use in agricultural,diverse industrial manufacturing process etc.)and being an ultimate sink for al types pollutants,the soil pollution are receiving increasing attention as potentially important pollutants.To assess health hazard and other problems posed by metal component,information is needed on their concentrations,particle size and chemical forms.So the toxic and trace metals concentration in dust,dustfall(aerosols),soil is reviewed.
