Abstract

In this study, drinking water samples were collected at certain area of Hong Kong. The nonvolatile organic compounds(NOC_s) in water were concentrated on resin and examined by using the Salmonella mutagenicity test(Ames test). The mutagenicity of such concentrates recovered from 1 to 2 liter drinking water could be detected by means of S.typhimurium TA98 with and without S9 m. In addition,the filtration of activated carbon could remove a part of NOCs from drinking water and therefore decrease the mutagenicity.
