South Taihu Lake used to get less attention in terms of environmental pollution study in the past. Sediment and fish samples were collected from South Taihu Lake in 2009. Heavy metals were measured for both types of samples and potential health risks were evaluated. Concentration of Cu, Zn, Cr and Ni were determined for sediments samples, and Cu, Zn, Ni, Fe and Mn were determined for fish samples...
With the Tessier Five-step Continuous Extracting Method, the thesis studied the form distribution of heavy metals in the sediment samples collected from Mochou Lake, Xuanwu Lake and Qinhuai River in Nanjing, analyzed the correlation between leaching contents of heavy metals and various forms and between content of organic matter and leachability of heavy metals and between organic matter and organic...
Nutrient has been considered to be undoubtedly one of the key factors stimulating algae growth. By a series of experiments the relationship between nutrient elements and phytoplankton growth was explored in three lakes: Lake Yezhihu, Lake Tangxunhu and Lake Nanhu, located in Wuhan City, China. We undertook 5 days in-site incubation experiments in the late April, 2007. The results showed that the chlorophyll...
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,...
