Bioavailability of Heavy Metals in Urban Surface Dust and Rainfall-Runoff System
城市地表灰尘-降雨径流系统重金属生物有效性研究

A sequential digest was used to examine the speciation of particulateassociated heavy metals in multi-media environment of surface dust and rainfallrunoff system.Within the Shanghai central district,different environment medium in four sites were sampled including street dust,runoff suspended particles,gully pot sediment and river sediment during April 2006.The result shows that in the study area,heavy metal concentrations of surface dusts are significantly higher than the Shanghai soil background values an...
