Mutagenicity of sediment and water samples from Nif brook (Western Turkey)

WOS: 000254383700002In the present study, water and sediment samples from 7 sites on Nif Brook and 1 site on Gediz River were studied for their mutagenic potential in TA98 and TA100 strains of Salmonella typhimurium using Ames test (plate incorporation assay) without metabolic activation. Extracts of the sediment samples were assayed in five different concentrations, and mutagenicity results were obtained for two strains from different sampling sites. Without metabolic activation, sediment samples were either non-mutagenic, weakly mutagenic or strongly mutagenic; and water samples were found not to be mutagenic. Results of the present study suggest that complex pollutants discharged to Nif Brook are accumulated in the sediment rather than in the water, and regarded to be lipo-soluble pollutants. The present study is of importance in terms of being the first one on pollution in Nif Brook
