上海医科大学和启东肝癌研究所协作,先后6次对江苏省启东县和上海市南汇县饮用不同水型的居民各约10万人进行了肝癌发病(死亡)率的调查,结果证明饮沟塘地面水居民肝癌发病(死亡)率高,而饮井水(浅井或深井)者肝癌发病(死亡)率低,前者约为后者的9倍,且这种高低差异不能用乙型肝炎感染和黄曲霉毒素污染来解释。启东县改善饮水条件后肝癌发病(死亡)率趋于稳定,而邻近饮水条件未变化的海门和南通、如东地区肝癌死亡率近几年来已超过启东县。目前,在肝癌病因尚未确定情况下,这
In collaboration with Shanghai Institute of Hepatology, Shanghai Medical University and Qidong Institute of Histology conducted a survey on the incidence (death) rate of liver cancer of about 100,000 people each with drinking water of different water types in Qidong County, Jiangsu Province and Nanhui County, Shanghai Municipality. The results showed that drinking ditch pond The incidence (death) rate of HCC in surface water residents is high, while the incidence (death) rate of HCC in drinking water wells (shallow wells or deep wells) is low, the former is about 9 times that of the latter, and the difference can not be detected with Hepatitis B Aflatoxin contamination to explain. In Qidong County, the incidence (death) rate of liver cancer tends to be stable after drinking water is improved, while the mortality rate of liver cancer in Haimen and Nantong and Rudong areas near the drinking water environment has exceeded Qidong County in recent years. At present, in the etiology of liver cancer has not been determined, this
