Abstract: Purified water for drinking is one of typical advanced treated drinking water. A series of experimental studies carried on by our team since 1998 showed that although drinking purified water was safer than tap water, filtered water and boiled tap water in terms of genotoxicity, it might decrease some mineral levels in organism and increase lipid levels if long time dinking, thereby threaten cardiovascular system.Meanwhile,if drinking eraly since in perinatal period, young children might displayed light hysteresis in nervous system. Our suggestion is that we should intensively enhance drinking water resourse protection in order to avoid the double losses in economic and human health owing to advanced treatment in drinking water.

Key words: drinking wate, purified water, health effect
