一、问题的提出千沸水指反复多次烧开的水。亚硝酸盐是一类常见的无机盐类,人体吸入一定量的亚硝酸盐可导致呼吸困难、循环衰竭、中枢神经受损等症状,此外,亚硝酸盐能与机体内的胺或酰胺形成强致癌性的亚硝基化合物。网上盛传“千沸水”中含有大量亚硝酸盐,饮用“千沸水”会致癌。对此,笔者对“千沸水”中亚硝酸盐的含量进行实验探究,以化学实验的方法审视其正确性,以期帮助人们拨开迷雾,树立科学的饮水观念。
First, the question raised Thousands of boiling water refers to repeatedly boil water. Nitrite is a common class of inorganic salts, the body inhaled a certain amount of nitrite can lead to breathing difficulties, circulatory failure, central nervous system damage and other symptoms, in addition, nitrite and the body can form strong amine or amide Carcinogenic nitroso compounds. Online rumors “a thousand boiling water ” contains a lot of nitrite, drinking “a thousand boiling water ” can cause cancer. In this regard, the author of “a boiling water ” in the nitrite content of experimental exploration, chemical experiments to examine its correctness, with a view to helping people to open the fog, establish a scientific concept of drinking water.
