Evaluation of Environmental Water Quality by Application of Comet Assay with Unicellular Protozoan Tetrahymena thermophila
Unicellular protozoan Tetrahymena thermophila was used in comet assay to detect DNA damage induced by wastewater so as to evaluate water quality. Results showed that a fine dosages-response relation between H2O2 and DNA damage was presented. Water from East Lake and the Yangtze River did not induce visible DNA damage while effluent from a printing and dyeing plant induced significant DNA damage which could impact on normal ecoenvironment.
