[Study on the effect of micronucleus with drinking water in the high risk area of stomach cancer].
Mutagenicity/Carcinogenicity of samples of drinking water supplies in the high risk area of stomach cancer was studied with micronucleus test and the epidemiologic method in Zanhuang county, Hebei. The results showed that the micronucleus cell rates in NIH mice induced by concentrated drinking water samples from the high risk area of stomach cancer were higher than those from low risk area and there was close correlation between degree of water concentration and micronucleus cell rates. This corresponded with the results obtained by the epidemiological method showed that the drinking water was obviously mutagenic and that it was closely correlated with the production of stomach cancer.
