Study on genetoxicity of organic extract in four kinds of drinking water

  Objective   To explore the effect of different kinds of drinking water on human health.

  Methods   To test the genetoxicity of the organic extract in tap water, pure water, defecated water and boiled water by single cell gel electrophoresis assay and micronucleus test.

  Results   The degree of the DNA damage of the organic extraction is as follows: tap water > defecated water > boiled water > pure water, and the degree of the chromosome aberrated is boiled water > tap water > defecated water > pure water.

  Conclusion   Pure water is better than other water from the point of organic pollutant, but the comprehensive effect of pure water on human health should be further studied.
