贵屿电子垃圾处理对河流底泥及土壤重金属污染
Heavy metals in sediments and soils contaminated by electronic waste recycling in Guiyu town
摘要
Abstract
A field investigation was carried out on characteristics of heavy metals in the sediments and soils nearby electronic waste recycling sites in Guiyu town, Shantou city, Guangdong Province. The results showed that the concentrations of Cd, Ct, Cu, Pb, Zn were 52.9～67.1,309～359, 79.2～1485, 391～449, 37.5～111 mg·kg-1 in sediment, respectively. Concentrations of Cd, Cr, Cu, Pb, Zn were 54.1～57.1,278～320, 93.5～116, 382～415, 46.2～68.1 mg·kg-1 in soil, respectively. Concentrations of Cd, Cr, Cu and Pb were more than the secondary category of soil environmental quality standard (GB 15618-1995), of which the most serious pollutions were Cd and Cu. The geochemical distribution of heavy metals in sediment and soil is similarly. The mobility of heavy metals were Cd＞Cr＞Pb＞Zn＞Cu.关键词
