Determination of optimal sampling transects and pollutants for river sediments are essential and valuable. To determine if the concentration of some metals were highly correlated, correlations between heavy metals (As, Pb, Cd, Cr, Hg, Cu, Ni and Zn) were analyzed using statistic analysis software (SAS) based on monitoring data of heavy metals along the whole watercourse sediments of Dagu River. To...
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,...
To reveal the spatial variability of soil heavy metals under the influence of urban expansion, Yingxing city of Jiangsu province was selected as study area. Three transects were arranged in the urban-rural ecotone. 24 surface soil samples were collected. And the contents of heavy metals including Hg, Pb, Cu and Zn were measured and analyzed. The results were as follows: (1) Hg contamination and Pb,...
