Popis: The genotoxicity of drinking water have received increased attention in recent years to assess aquatic ecosystem safety. The factors affecting the genotoxicity of drinking water, including sample preparation, the concentration of bromide and ammonia nitrogen (NH3-N), were investigated using umu test. The result showed that sample preparation and bromide could significantly influence the genotoxicity of drinking water. During sample preparation, 1 and 2 L waters concentrated were suitable for umu test and the highest yield for genotoxic compounds was obtained from acid solution (pH 2) when ethyl acetate served as the eluant. Bromide could substantially increase the genotoxicity of drinking water after chlorine disinfection. The genotoxicity of drinking water could not be increased with increasing NH3-N concentration.
