摘要
对胃癌高发区长乐县漳港乡(1976～1983)、古槐、潭头、文岭、金峰、首占、漳港6个乡(1986～1988)上消化道及其他恶性肿瘤死亡率与饮水关系的回顾性研究表明,漳港乡饮用河水组的上消化道肿瘤死亡率明显高于井水组(P<0.01);6个乡饮用河水组略高于井水组。饮用处理水组胃癌、食管癌死亡率明显低于原水组(P<0.01,P<0.05),死亡率分别下降31.95%,37.33%,而其他恶性肿瘤死亡率与不同饮用水源未呈现此规律性。
The report discusses using the retrospective study to assess relationship between drinking water and cancer death rate of upper digestive tract and the others in Changle county-a high incidence are a of the stomach cancer.The study was carried out in 1976～1983(one town)and 1986～1988(6 towns). The results revealed that among the population drinking the river-water,death rate of cancer of upperdigest ive tract was higher than that of those drinking well water from 1976～1983,but ths rats was only a little higher in six towns.Furthermore compared with drinking purified water,the death rate of cancer from the stomach and esophageal was significantly lower than that with the raw water,the decreased rates were 31.95%,37.33% respectively,but the others were not related to drinking water. The signicant difference was made by using purified water,it is suggested that some organic materials might be contaminated in the river water.It is a topic to be studied in the future.
