Chinese tea culture has a long history ,moncler outlet usa whether ancient or modern , most families still used to drink boiled water. However, boil water and drinking water is also a lot of stress , especially now that water pollution , healthy drinking water do not pay attention , it's easy to get sick. Then boil water should pay attention to what point it ? Quick open when water (80 ? -90 ?) should open the lid . Because more and more organic pollutants in water , some substances are volatile when heated with steam volatile out. Therefore, when you put in the water fast boil kettle lid open , allowing these substances to maximize volatilization out. Water to a boil for about 3 minutes after the other and then turn off the heat ! This is because: ordinary water lakes water into the plant,Moncler Coats to go through chlorination , to remove microorganisms and other impurities , but at the same time , chlorine organic residues interact with water , will form a halogenated hydrocarbon , chloroform and other toxic carcinogenic compounds and halogenated hydrocarbons, chloroform content and duration of changes in water temperature and the boiling length are closely related. Water temperature reaches 90 ?, halogenated hydrocarbon content increased from 53 micrograms per liter up to 191 micrograms, Moncler Jackets 43.8 micrograms per liter of chloroform by a rise to 177 micrograms , exceeding the national standard two -fold. When the water temperature rose to 100 ?, halogenated hydrocarbons and chloroform levels decreased to 110 micrograms and 99 micrograms, still exceeds the national standard. If you continue to boil for 3 minutes, halogenated hydrocarbons and chloroform levels were reduced to 9.2 micrograms and 8.3 micrograms , then became safe drinking water. Of course, water is not burned as long as possible , because the longer burned , non-volatile harmful substances in water and nitrite , because concentrated by evaporation of water , moncler usa were relatively increased, drinking such water , the same body harmful .
