Grey Correlation Analysis between Liver Cancer and Drinking Water Quality in Southeastern Coastal Areas of China

摘要

Using grey correlation analysis to the relationship between the incidence of liver cancer and drinking water quality in Fujian , Jiangsu , and Guangxi provinces, considering the basic features of the original and the secondary environments in the study areas, the following conclusions can be drawn: liver cancer can be caused by many factors and drinking water may be among the most important ones; minerals (e.g. Ca2+, Mg2+, Mo, Zn, etc. ) needed in drinking water by human body in southeastern coastal areas of China are relatively low; Ca2+ , Cu ,NO2- etc . are closely related to the incidence of liver cancer.
