'clock last night, the test results came out. Detected in water samples, the lowest content of nitrite in tap water, "thousands of boiling water" Second, the highest nitrite content turned out to be mineral water content of 1.69 milligrams per liter. Laboratory personnel, mineral water is not pure water, so the water containing nitrite ion is relatively normal, http://www.woolrichoutletevipit.com - woolrich outlet . "Drinking water health standards" (GB5749-2006), our standard of drinking water NO3-N (nitrate concentration of nitrogen) is 10 mg / L, and experimental testing of all water samples are in line with this standard. By intake nitrite in thousands of boiling water to reach toxic dose at least disposable drinking 20 tons of "thousands of boiling water, which is simply impossible. Conclusion boiling water, the more the number of lower levels of nitrite test results show that the mineral water watery heated nitrite levels have decreased. Heated twice watery lower than heating water samples nitrite content, http://monclerofficialujp.webnode.jp - モンクレール . Laboratory personnel, said the the nitrate ion oxidation state, while the nitrite ion reduced state. When the water is boiling, nitrite ion in water only may be converted to nitrate ion, http://gucciofficialstoreybjapan.webnode.jp - グッチ , which is why water nitrite concentration with the increase in the number of water heating, not only will not rise, but it also reduces the reason. Reminder of the laboratory personnel, the reporter found that the nitrate content of water samples heated to boiling mineral water has its own elevated, and boil the more the number, http://monclersitoufficialeyitaly.webnode.it - moncler , the higher nitrate content in water. It happens also confirms the argument of the laboratory personnel. Visible, thousands of boiling water with high nitrite content argument is purely rumor. Doubts of nitrate, http://monclerofficialujp.webnode.jp - モンクレール ダウン , nitrite come from Experimental Center Professor Liang Fu told reporters, our drinking water from natural water bodies. Part of the surface water, when this part of the water flowing through some areas, such as farms or farmland, http://duveticastorekjapan.webnode.jp - デュベティカ , nitrogenous fertilizers and feces of livestock and poultry farms in the farmland contaminated. Another part of the groundwater, when the city landfill from groundwater sources near water bodies may also cause infiltrated the nitrite, http://uggboottofficialtjapan.webnode.jp - UGG ブーツ . This is because the water is nitrate contamination by microorganisms, http://uggboottofficialtjapan.webnode.jp - アグ , and then converted to nitrite, http://monclersitoufficialeyitaly.webnode.it - moncler outlet . In the production of tap water, the need for filtration and precipitation steps. "Filter, although not one hundred percent removal, but most of nitrite and nitrate are filtered out, so people do not have to worry about."
