Water temperature machine it is thousands of boiling w
We all know that thousands of boiling water is best not to drink, drink harmful to the body, and now peoples lives, many people use temperature machine, the water temperature machine is thousands of boiling water it? Xiaobian a look at it.
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, thousands of boiling water on the body is? Some experts believe that repeated boiling of water to drink easily diarrhea, and some experts believe that thousands of boiling water is not harmful to the human body, each has to say, but small series that regardless of the thousands of boiling water is harmful to the human body, its best drink less as well, lets take a look at water temperature machine is thousands of boiling water it?
is repeated heating temperature machine plays a role of a thermostat, the temperature change is small, the water does not boil, no nitrite, so that the temperature machine is not thousands of boiling water, can be assured drink.
life, I am sure you have heard of such a statement, "repeated boiling of water, that thousands of boiling water", can not drink, "because nitrite content" thousands of boiling water in the excessive consumption of a variety will lead poisoning and even cancer ...... "this really the case?
First to understand nitrite. Nitrite is a generic term for a class of inorganic compounds, nitrite ingestion of 0.3 ~ 0.5g, can cause poisoning or death. Drinking water health standards of our requirements, nitrite content should be 1mg / L.
beginning of the experiment. Before boiling water, nitrite content of ordinary tap water before test. Data show that the content of nitrite in water was 0.007mg / L, far below the national standard.
ignition, boiling water (FIG). Boil once detected. Sure enough, nitrite content of water increased to 0.021mg / L. However, even if the value increases, is still far below the national standard, indicating that water quality is still very safe at this time.
Subsequently, again repeatedly opened fire to boil water. Water boil test respectively 5 times, 10 times, 20 times is recorded, the results show, the content of nitrite has been slowly rising, respectively, 0.028mg / L, 0.03mg / L, 0.038mg / L. Why is this?
China Disease Prevention and Control Center environment assistant researcher Chen Xi said repeatedly boiled tap water, at highCase temperature of oxygen, is conducive to the conversion of nitrate to nitrite. But data shows that even boiled tap water 20 times, which the nitrite content is far below national standards, is safe. Moreover life, we simply can not boil drinking water 20 times.
By Xiao Bian introduction to this article, all of the thousands of boiling water is not a new understanding, if you want to know the water column full of small family knowledge, please continue to focus on Internet cafes.
