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...
Based on the ISCST3 model and the health risk assessment model recommended by U.S.EPA, a new health risk assessment of atmospheric environment was set up for hazardous wastes landfill disposal. The atmospheric environmental health risks of the electroplating sludge into the general industrial solid waste landfill were evaluated to verify the effectiveness of this method. The results showed that this...
Taking an urban sewage river in north China as study object, total concentrations and concentrations of different chemical forms of heavy metals in surface sediment samples are determined. The relative enrichment factors and the potential ecological risk index, Hakanson index, are taken to study the pollution status of heavy metals in sediments and assess the potential ecological risk. The results...
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...
