The impact study of hexavalent chromium on the environmental safety of the drinking water source from the jiangsu section of the yangtze river basin

In this paper, a health risk model was used to calculate and analyze the water quality monitoring data of the Yangtze River Basin from 2007 to 2009. The data analysis leads to a conclusion that hexavalent chromium is a major health risk factor of those drinking water sources in the Jiangsu section of the Yangtze River basin. Based on the health risk analysis, an environment strategy analysis model and the Dynamic Actor Network Analysis(DANA) software were used to study the optimal strategy on the risk management of chromium contamination of those drinking water sources in the Jiangsu Section of the Yangtze River basin. © (2013) Trans Tech Publications, Switzerland.
