130 wet deposition events were observed at the summit of Mt. Tai (East China, 1534 a.s.l) in China during Jan. 2005 to Dec. 2008. Zn, Al, Mn, Fe, Pb, Cu, Ni, Cr, As, and Cd were determined by ICP-MS to evaluate the characteristics of heavy metals in wet deposition at Mt. Tai region. The concentrations of these metals are generally higher at Mt. Tai than the concentrations observed at other monitoring...
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...
Dustfall samples were synchronously collected at five typical urban functional areas (industrial area, traffic area, residential area, cultural and educational area, residential and commercial mixed area) of Pingdingshan City in Henan Province from May 2008 to April 2009. The principal component elements in dustfall samples were analyzed for concentrations, spatial distribution, sources and contributions...
An investigation was conducted on the characteristics and leaching behavior of heavy metals from municipal solid wastes incineration (MSWI) fly ash in Chongqing, China. Results indicated that the average particle size of the fly ash was 36.4 μm, the large particles were formed mainly by small particles' adsorption or aggregation. The total content of the main heavy metals was about 1.04% of the fly...
