Six specific types of surface dusts were collected from different e-waste disposal areas in Shanghai, China for the determination of toxic metals including Zn, Pb, Ni, Cd, Cr and Cu. These samples were obtained from interior of home appliance, second-hand household appliance maintaining store, open manual dissembling yard, enclosed electronic waste warehouse, enclosed dissembling workshop, as well as outside yard of plant. ICP-AES analyzing results revealed that metal concentrations in dust from home appliance interior and second-hand household appliance maintaining store were obviously higher than the soil background values. And the metal concentrations of dusts from open manual dissembling yard were similar to enclosed electronic waste warehouse. The concentrations of Pb, Zn and Cu in dust from enclosed dissembling workshop were about 3646.10, 3485.23 and 4049.70 mg/kg, which were respectively 9, 19 and 45 times higher than outside yard of plant. The potential ecological risks of metal pollution in these dusts were analyzed by estimating the distribution characterization of samples and the heavy metals. The results showed that potential ecological risk of Cu was the highest, and then was the Cd, Cr was the least. The ecological risk indexes of metals in dusts from enclosed dissembling workshop, home appliance interior and second-hand household appliance maintained store were considered to be significantly healthy harm, while those from open manual dissembling yard and enclosed electronic waste warehouse were relatively less harm.
