Abstract :
Soil samples of 0-15cm from 9 sampling sites including different functional zones and different greening types of Shanghai, China were collected and analyzed. The results showed the average concentration of Cu, Pb, Zn and Cd in soil of shanghai were up to 42.33,169.58,49.06, and 0.2460mg/kg, respectively, which were much higher than their natural background values. Among the functional zones and the greening types, the school regions and the shrub type displayed the highest metal concentrations. The metal concentration of 0-5cm layer was higher than other soil layers. Potential ecological risk indices (RI) indicated that Shanghai was suffering from low metal contamination. The order of potential ecological risk index was school > arboretum > roadside greenbelt > residential area>industrial region.
