Abstract :
Atmospheric deposition samples were collected and analyzed from 50 sampling sites in Baoshan district, Shanghai. The results show that the average concentration of Pb, Cr, Cd, Zn and Cu is 281.88, 254.45, 7.06, 2433.92 and 3321·08mg-kg-1 respectively, which are much higher than background values of soil in Shanghai. The spatial distribution features of live heavy metals illustrate higher concentrations in industrial and heavy traffic areas. The order of potential ecological risk is Cd> Cu> Pb> Zn> Cr. Baoshan is suffering a considerable risk, and metal contamination in this district is serious.
