作者多年对苏联阿塞拜疆鞑靼地区600口水井进行调查,发现有50%以上硝酸盐浓度超过卫生标准,其中不少达100 mg/l。在此基础上用大鼠实验研究饮水中硝酸盐对温血动物的影响。大鼠分三组,每组6～8只。第一组给普通自来水作对照组,第二组给硝酸盐40 mg/l的水,第三组给硝酸盐105 mg/l的水。各组大鼠高铁血红蛋白正常水平在实验开始时为1～ Over many years, the author investigated 600 wells in the Soviet Tata region of Azerbaijan and found that over 50% of nitrate concentrations exceeded sanitary standards, many of which amounted to 100 mg / l. On the basis of this, we used rat experiments to study the effect of nitrate in drinking water on warm-blooded animals. Rats were divided into three groups, each group of 6 to 8. The first group used ordinary tap water as the control group, the second group with nitrate 40 mg / l and the third group nitrate 105 mg / l water. The normal level of methemoglobin in each group was 1 ~ at the beginning of the experiment
