These material are to be in fountainhead or be defeated by conduit canal to enter drinking water. What these material can affect human body is neurological, cause cancer, cause haemal part disorder. Volatile organic matter (VOC) these are easy volatilize to contain carbolic compound mediumly to air by water system. Basically originate the direct or indirect pollution such as reservoir of chemical of solvent, insecticide, industrial waste water, underground, include carbon of benzene, 4 chloridize, 7 chloric etc. The harm of these compound and cancer and fecundity is concerned.

When water temperature rise reachs 90 degrees, the content of halogenate hydrocarbon is 3 times original, exceed national standard of potable water double, lift when temperature 100 degrees when, chloridize hydrocarbon is met as evaporate and decrease greatly, if can continue boil 2 minutes, better.
