由于硝酸盐在消化道内转化为亚硝酸盐后可能会引起婴儿的正铁血红蛋白症,并且还发现引发其它一些疾病,世界卫生组织建议饮用水的硝酸盐含量不应高于50mg/L。在世界许多地方,地下水的污染是一个日趋严重的问题,多数情况下,这个问题的根源在于集约农业过程中过量地使用氮肥,不过,在某些酸环境下,如澳大利亚中部,自然条件下亦发生这种硝酸盐污染。在卫生状况普遍落后的发展中国家,硝酸盐对村落的危害最大。我们对爪哇和龙目多处井水的硝酸盐富集进行的广泛调查进行报道,结果表明,在人口密 Because nitrate can cause methemoglobinemia in infants after it is converted to nitrite in the digestive tract, and other illnesses have also been identified, WHO recommends that the nitrate content of drinking water should not exceed 50 mg / L. Groundwater pollution is a growing problem in many parts of the world. In most cases, the root cause of this problem is the excessive use of nitrogen fertilizers in intensive agriculture. However, in some acid environments, such as central Australia, natural conditions This nitrate pollution occurs. In developing countries where the general health status is lagging behind, nitrate is most harmful to the villages. We conducted extensive surveys of nitrate enrichment in many wells in Java and Lombok. The results show that in dense population
