为进一步探讨赞皇县胃癌高发区饮水与胃癌发生的关系，分别以水源类型和饮水习惯的问卷调查、饮用水源水质分析方法对赞皇县癌高发区和相对低发区（胃癌年均死亡率分别为１０５～１２６／１０万和３６．３／１０万）进行对比研究。结果发现，赞皇县胃癌高发区居民饮用河水及饮生水习惯者均明显高于相对低发区。饮水水源水质分析结果表明，两地饮水微生物检出率均明显超标。高发区饮水在硬度、镁、氟、钠、ＮＯ－３、硝酸盐和亚硝酸盐的含量上均明显低于相对低发区。两地饮水水源中农药残留均未超标。
To further investigate the relationship between drinking water and gastric cancer in Zanhuang County, a high-risk area of gastric cancer, a questionnaire survey of drinking water types and drinking habits, drinking water quality analysis methods, and high incidence of cancer in Zanhuang County and relatively low incidence areas (gastric cancer deaths per year The rates were 105-126 per 100,000 and 36.3 per 100,000 respectively. As a result, it was found that the drinking habits of drinking water and drinking water in residents of high incidence areas in Zanhuang County were significantly higher than those in relatively low incidence areas. The drinking water source water quality analysis results showed that the detection rate of drinking water in the two places was significantly exceeded. Drinking water in the high-incidence areas was significantly lower than the relatively low incidence areas in hardness, magnesium, fluoride, sodium, NO-3, nitrate, and nitrite. The pesticide residues in the drinking water sources of the two places did not exceed the standards.
