How often do you drink water from the water fountain?
Healthy drinking water should meet the following requirements: no pathogenic bacteria, heavy metals and harmful chemicals; containing minerals and trace elements; containing fresh and appropriate dissolved oxygen; partial alkaline; small molecular mass of water; strong activity. Experts pointed out: regular manufacturers of drinking fountains and bottled water basically meet this requirement, "toxic said" does not hold water.Domestic consumers like to drink boiled water and tea, so the heating function of water heater is very important. At present, almost all domestic drinking fountains have heating bladder. Equipped with heating bladder to make the drinking water machine more convenient to use, but there are also some problems, the drinking machine "poisonous said" is based on this. In this regard, the Chinese Medical Association will promote healthy drinking water, Specialized Committee director Li Fuxing refuted, and gives some solutions to the problem.
Whether at home or office, we have long been accustomed to the convenience of drinking fountains, fast, boiling water has become a long memory. However, recent media reports: a drinking water machine enterprises from exposing insider, "the domestic heating liner drinking machine up to 99.3% of all are poisonous"! The news immediately drew an uproar. In March 1st, the State Administration announced that the news was purely corporate speculation and was not credible. Experts point out: the real health risks of drinking fountains are not here.
First, scaling: water dispenser prone to scale, especially in areas of high water hardness. The white precipitate that appears is mostly carbonate. In fact, these salts exist in a very stable compound form, and there is no evidence that it is harmful to humans. But the existence of these substances affect the efficiency of heat exchange, fouling serious, it will bring security risks. Therefore, drinking water timely descaling.Two, "thousands of boiling water": this formulation is not scientific. The heating temperature of the water heater is generally 85 DEG C, ~95 DEG C, and the boiling temperature is not reached. But the activity of long-term heating of water will affect the heating time in the water activity of the poor, commonly known as "aging water", so in a long time without drinking, should turn off the power, in addition to saving, but also avoid the loss of water activity.Three, the water dispenser contains nitrite: as the water contains nitrate nitrogen, when the drinking water machine microbial pollution is serious, it will make nitrate nitrogen into nitrite nitrogen. When the WHO drinking water directive specifies that the target exceeds 3mg/L in the short term, the baby will suffer from methemoglobin. From the current study, there is insufficient evidence to suggest that nitrite is directly related to cancer.
