Thousands of boiling water toxic it
Water is the source of life, and the most healthy than plain water. However, recently, a network of thousands of boiling rumors circulated on the Internet, then thousands of boiling water poisonous? Let Xiaobian to tell you now.
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. White-collar office in the usual drink of water, mostly boiled water room or boiler burning out, thousands of boiling water on the body is? This water due to repeated boiling, will lead to an increase in nitrite and other harmful substances, toxic nitrite will result in hypoxia, severe convulsions, coma, and even death, so thousands of boiling water poisonous?
Anyway, revolves around the so-called poisoning "nitrite", which is a generic term for a class of inorganic compounds, mainly refers to sodium nitrite. Salty taste of sodium nitrite, soluble in water, and the appearance and taste similar to salt, is widely used in industry, construction industry, meat products it also allows limited use as color formers, food poisoning due nitrite the higher the probability, so countries have strict controls on the use of nitrite.
how will this substance in tap water it? The reason is that people drinking water from natural surface water or groundwater. Because nitrates, nitrites soluble in water, surface water nitrate, nitrite may slowly penetrate into the groundwater; Further, water contained in the nitrate, there may be microbial contamination, converted to nitrite salt.
Although nitrite carcinogenic, but by carcinogenic nitrite in water, really not easy. Generally the bodys intake of nitrite disposable safety of 0.2 mg per kilogram of body weight, drinking water health standards, the provisions of the nitrite content of not more than 10 mg / l, if you are not more than 10 liters of drinking water one time, then It is safe.
As thousands of boiling water, resulting in "nitrite" elevated levels of the same statement is only a guess. "Thousands of boiling water harmful to human health rumors there is no scientific basis, to poisoning by thousands of boiling water is not easy." Wu Zhigang said.
This is supported by data, experimental results from a university: boiled with increase in the number of nitrite content of the water is not significantly increased. And all the nitrite content of water samples, were lower than my countrys "drinking water health standards" (GB5749-2006)Nitrite content in the predetermined limits of 10 mg / liter. Specific data can be seen in this edition pictures, thousands of boiling water in the nitrite content even lower than mineral water.
These are the thousands of boiling water if small series to introduce the poison content, I believe we should have a own understanding of this, but there are no toxic matter, is best drink less as well, and finally to remind you the family is to know more about drinking little knowledge, escort for the health and safety of our families.
