The upstream of Bi River is originated from the Laping Lead-zinc Mine which is the biggest one in China. Therefore, Bi River was affected by mining activities of Lanping Lead-zinc Mine, and had become a typically polluted river by heavy metals. According to the measurement on the magnetic susceptibility and heavy metal pollution in the sediments of Bi River River, the present situation of heavy metal...
Soil samples (0-10cm soil layer) were collected from Xuanwei and Fuyuan, which were known as high lung cancer incidence area in Yunnan province, China.The aim of the study was to investigate the trace metal pollution situation of the local village. Total 24 samples of surface soil were analyzed for 32 trace metals. The samples were digested with HNO3 and HF and H2O2 using microwave. The concentrations...
Twelve samples of surface sediment in Nanhu Lake, Wuhan city were collected and the concentrations of Organic Matter (OM), Total Nitrogen (TN), Total Phosphorus (TP), ammonia nitrogen (NH4+-N) and nitrate nitrogen (NO3--N) were determined; the average result were 6.58%, 3972, 1712, 897 and 20mg/kg separately. Cd, Hg, As, Cu, Pb, Cr and Zn were determined too; and the average value were 0.46, 0.140,...
The heavy metal pollution on atmospheric dust made by fire coal of city power plant is receiving more and more attentions, but spatial and temporal effect researches on fire coal amount and heavy metal pollution of atmospheric dust after enterprise' relocation out of urban area are comparatively less. This paper studied three thermal power plants in east city and Beihu Park on the outskirts, doing...
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...
