A descriptive epidemiological research, within the Piemonte Region was carried out, to consider whether there is an association between concentrations of nitrates in drinking water and the incidence of gastric carcinomas. The results indicate that an association does exist, but also that concentrations of nitrates higher than 20 mg/l in drinking water are a risk factor for people exposed.
在皮埃蒙特地区开展了一项描述性流行病学研究，以探讨饮用水中硝酸盐浓度与胃癌发病率之间是否存在关联。结果表明，二者之间确实存在关联，而且饮用水中硝酸盐浓度高于20毫克/升对接触人群而言是一个风险因素。
