Zusammenfassung: | Asa river is a major river designated to supply millions of people of Ilorin, Kwara State, Nigeria potable water for drinking but its managements is of grave concern due to anthropogenic activities. Thus, evaluation of genotoxicity of this river was carried out by subjecting the water samples and fish therein to three bioassays (Micronucleus (MN) assay, Ames test and SOS-chromo test). Physicochemical parameters and heavy metals were analysed at three different stations (Aliara (SI), Unity (SII) and Tuyil (SIII)) of the river. In SII, most of the heavy metals analysed were above the acceptable limits compare to SI and SIII. The peripheral erythrocyte of the fishes (
) at SI and SII stations showed a significant (p |
