The pollutants in urban storm runoff, which lead to non-point source contamination of water environment around cities, are of great concerns. The distributions of typical contaminants and the variations of their species in short term storm runoff from different land surfaces in a seaside city in South China were investigated. The concentrations of various contaminants, including organic matter, nutrients...
Based on the investigating the inter-tidal water environment in Qinhuangdao section, the distribution characteristics of ammonia nitrogen, chemical oxygen demand, Zn, Cd and other metal elements in the water body and the pollution characteristics of Cu, Pb, Zn and Cd in surface sediment were studied. The results showed that Cd, chemical oxygen demand and ammonia nitrogen are the main pollutants in...
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,...
Characterization of urban stormwater runoff was carried out in commercial, residential and cultural and educational zones during 2009 rainy season in Tianjin. The pH, DO, BOD5, COD, TOC, TSS, TN, TP, NH3-N, As, Pb, Zn, Cd, LAS and fecal coliforms in stormwater runoff were analyzed. The ranges of arithmetic mean concentration of COD, TSS, TN, LAS and fecal coliforms were 67-331 mg/L, 134-480 mg/L,...
The extensive clayization of Dexing copper mine is responsible for water and soil pollutions because of the oxidation of sulfide minerals. During the clayization, harmful elements such as As, S, Sb and Pb could be effectively released into the clay and water. Using the abundant spectral information of short wave infrared (SWIR), combining with the spectral absorbed index, SAM (Spectrum Angle Mapper)...
