Abstract: ObjectiveTo study the correlation between the status of water pollution and cancer mortality.MethodsInvestigation into water pollution and the cause of death were carried out in some parts of Fuqing and Yongtai.ResultsThe indexs above the national standards in drinking water were pH,fluoride,lead,iron,manganese.The over standard rate of manganese in Fuqing was significantly higher than that in Yongtai.The over standard rate of total nitrogen and total phosphorus in Fuqing was 55% and 25% respectively,and the rate in Yongtai were 0%.The rate in Fuqing was significantly higher than that of in Yongtai(P<0.05).The positive reaction rate of microcystin in Fuqing was 46.5%,which was significantly higher than that of in Yongtai(11.1%,P<0.05).The standar dized mortality of cancer in Fuqing was one time higher than that of in Yongtai.The standar dized mor tality of esophageal,stomach,liver,colorectal,lung and bladder cancer in Fuqing were higher than those of in Yongtai.ConclusionThe high mortality of cancer in Fuqing may be correlated with water pollution.
