The contents and characteristics of ten heavy metals in surface sediments from Yangzonghai Lake in Yunnan, China were analyzed. Ecological risk index presented by Håkanson to assess the potential ecological risk of Yangzonghai Lake was utilized. The results showed that the average concentrations of titanium(Ti), manganese(Mn), zinc(Zn), vanadium(V), chromium(Cr), copper(Cu), nickel(Ni), cobalt(Co),...
Environmental quality of reclaimed soil is a key issue in the process of land construction and ecology rehabilitation. Taking Xinzhuangzi and Datong reclamation district for example, according to Nemerow Pollution Index Method, results show that: In all 30 soil samples, 28 samples are I class level, clean; 1 sample is II class level, slightly clean; 1 sample is III class level, polluted slightly....
Ten sites along the XiJiang River (WuZhou section), China were sampled to evaluate the copper (Cu), Zinc (Zn), lead (Pb), cadmium (Cd), and chromium (Cr) concentrations in sediments. The order of total metal concentrations in sediment samples was found to be Zn>Cu>Cr>Pb>Cd. The approach of Hakanson potential ecological risk index was used for the ecological risk assessment. Compared to...
The unrestrained exploitation of coal resources lead to severe environmental problems in resource-exhausted areas in China. The environmental pollution and ecological damage degree are the basis to the eco-environmental restoration, both to determine the scope and to calculate the investment. So in ecological damaged area, to evaluate the damage degree is more important than evaluate the quality....
Given a description of city environment of Zhuzhou from the geochemical and geological environment, the author carried out further research on city ecological geochemistry and discussed the pollution of soil heavy metal through correlations analysis, R-cluster analysis and classified statistic of parent rock.
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...
The Yangtse delta area is one of the most rapidly developing areas in China. There are mega-cities like Nanjing and the surrounding urban areas of different sizes. As a traditional historical and industrial city, Nanjing city was investigated for heavy metals in its soil. Based on spatial characteristic of Nanjing City, 12 samples were regarded as descriptions of different function zone in urban area...
