Water is an indispensable and important material for human beings to live on. People can eat for a day without being waterless, but not all water can be consumed. The following five kinds of water will form nitrite to some extent. And other toxic and harmful substances will cause certain harm to the human body, so it should arouse people's attention. First, aging water: Commonly referred to as "deadwater", that is, long-term storage of immobile water. Often drinking this kind of water, for minors, will significantly slow down the metabolism of cells, affecting the growth and development of the body; the elderly will accelerate aging; in many places the incidence of esophageal cancer, gastric cancer is increasing, according to medical researchers , May be related to the long-term consumption of aging water. Relevant data show that toxic substances in aging water also increase with the increase of water storage time. Second, thousands of boiling water: Thousands of boiling water is the water that has boiled on the stove for one night or for a long time, and the water boiled repeatedly in an electric water heater. This water is boiled for too long, the non-volatile substances in water, such as calcium, magnesium and other heavy metal components and nitrite content is high. If you drink this water for a long time, it will interfere with people's gastrointestinal function, temporary diarrhea, abdominal distension; toxic nitrite will also cause the body to hypoxia, severe cases will be coma convulsions, and even death. Third, steamer water: The steamer water is steamed, steamed, and the like, especially after many repeated use of steamer water, the nitrite concentration is high. Regular consumption of this water, or the use of this kind of glutinous rice porridge, can cause nitrite poisoning; scale often enters the body with water, but also causes digestive, nervous, urinary and hematopoietic system lesions, and even cause premature aging. Fourth, not open water: Drinking tap water is sterilized and sterilized. Thirteen kinds of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects. When the water temperature reached 90°C, the content of halogenated hydrocarbons rose from 53 micrograms per kilogram to 177 micrograms, which exceeded the national drinking water hygiene standard by 2 times. Experts pointed out that drinking unboiled water increases the risk of bladder cancer and rectal cancer by 21% to 38%. When the water temperature reaches 100°C, these two kinds of harmful substances will be greatly reduced as the vapor evaporates. If it continues to boil for 3 minutes, it is safe to drink. Fifth, re-boiled water: Some people are accustomed to re-boil the remaining warm boiled water in the hot water bottle for the purpose of saving water, saving coal (gas), and saving time. However, this "saving" is not enough. Because the water burns and burns, the water evaporates again, and the nitrite will rise. Often drinking this water, nitrite will accumulate in the body and cause poisoning.
