Abstract: OBJECTIVE: To evaluate the in vivo genotoxicity of drinking and source water in Fuzhou. METHODS: Five districts were randomly chosen in Fuzhou with a water plant in every district. 200 liters drinking water and source water were sampled in every district. XAD_2 resin was used to extract the organic matter in water, and mouse bone marrow micronucleus and sperm abnormality test were used to detect the genotoxicity of the organic extractions. RESULTS: The drinking and source water of water plants in Changle city and Pingtan county and the drinking water of water plant in Fuqing city were mutagenic, and the genotoxicity of organic extractions of drinking water was higher than that of its source water. CONCLUSION: The drinking and source water of Fuzhou city had been polluted by organic compounds to some degree.

Key words: drinking water, organic extractions, in vivo genotoxicity
