4, not open water
people to drink tap water, are treated with chlorination sterilization. Chlorine-treated water can be isolated 13 kinds of harmful substances, whichIn a halogenated hydrocarbon, chloroform also has carcinogenic, teratogenic effects. When the water temperature reaches 90 鈩? halogenated hydrocarbons from the original content of 53 micrograms to 177 micrograms per kilogram to rise, exceeding the national drinking water standard 2-fold. Experts point out that not drink boiled water, suffering from bladder cancer, colorectal cancer is the possibility of an increase of 21% -38%. When the temperature reached 100 deg.] C, both harmful substances with greatly reduced vapor evaporation, such as boiling is continued for 3 minutes, then safe to drink.
