those stagnant water can not flow, and certainly not drinkable, we know why the stagnant water can not drink it? Xiaobian take a look at this knowledge of it.
With the economic level, most people are beginning to replace tap water with purified water, it is because tap water contains large amounts of harmful substances, not only water there is very stagnant water I there are also some hazardous substances, stagnant water in the end can not drink? The answer is not to drink, then there is to know why the stagnant water can not drink it?
because of stagnant water, no running water to replace, there will be a lot of bacteria in it and there are a lot of bacteria breeding! The water a long time will stink! Drinking stagnant water for minors, make cell metabolism slowed down, affecting their growth and development; it will accelerate the aging of the elderly; many parts of esophageal cancer, gastric cancer incidence increasingly higher, according to medical scientists who study may be related long-term drinking water-related aging. The data indicate that the aging of toxic substances in the water along with the increasing water storage time increases.
In addition to stagnant water can not drink outside, Xiao Bian finishing several water we drink is not:
1, raw water: drinking unboiled water, can lead to gastroenteritis, hepatitis, dysentery.
2, aging water: prolonged storage is immobile water, wherein the water toxic substances increases with storage time increases.
3, thousands of boiling water: thousands of boiling water on the stove is boiling water overnight or for a long time, as well as electric water heater repeatedly boiled water. For a long time to drink this water, it would interfere with peoples gastrointestinal function, a temporary diarrhea, abdominal distension; toxic nitrite will result in hypoxia, severe convulsions, coma and even death.
4, steamer Water: Water is the steamer steamed bread and other leftover pot of water, high water steamer nitrite concentration used repeatedly. Consumption of a variety of such water, or water boiled rice this will cause nitrite poisoning.
5, not open water: people to drink tap water, sterilized are treated chlorination. Chlorine-treated water 13 kinds of harmful substances can be isolated, wherein the halogenated hydrocarbons, chloroform also has carcinogenic, teratogenic effects. When the temperature reached 100 deg.] C, both harmful substances with greatly reduced vapor evaporation, such as boiling is continued for 3 minutes, it becomes safe.
6, re-boil water: it was customary in the remaining warm water thermos re-boil and then drink the purpose of water saving, when economizer (gas), sect. However, this "savings" undesirable. Because many times the boiling water will cause nitrite content increased.
household drinking water Tips: cool white open most suitable for drinking, especially insist on fasting morning drink a glass of cold water, there are illnesses and health effects. The so-called cold water, boiling water is poured into the cup, covered with lid, cooled to 20-25 鈩? After water cooling, its biological activity to be higher than the natural water 4-5 times, living cells and organisms in the water are very similar, so easy to penetrate the cell membrane is absorbed by the body.
