| industrial effluent induced chromosomal aberration in catfish from ogun river, lagos, nigeria. | the aim of the study is to evaluate the cytotoxic effect of effluents at inducing chromosomal aberrations, using this as a biomarker tool in wild clarias pachynema for assessing and monitoring pollution of the aquatic environment. a total of 60 live fish (30 each downstream and upstream) were obtained and subjected to chromosomal analysis. chromosomal aberration in the fish samples from the downstream sector was recorded at a rate of 30%, while there were no aberrations in the samples collected ... | 2014 | 26031000 |
| concentration of polychlorinated biphenyl (pcb) congeners in the muscle of clarias gariepinus and sediment from inland rivers of southwestern nigeria and estimated potential human health consequences. | the distributions of polychlorinated biphenyl (pcb) congeners were determined in sediment and muscle of the african sharptooth catfish (clarias gariepinus) from the ogun and ona rivers, southwest nigeria. in addition, the effect of pcb congeners on condition factor (cf) and associated human health risk was assessed using muscle levels for a noncarcinogenic hazard quotient (hq) calculation. elevated concentrations of high-molecular-weight (hmw) pcb congeners were detected in sediment and fish dow ... | 2016 | 27558803 |
