| 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 |
| biomarkers of oxidative stress and health risk assessment of heavy metal contaminated aquatic and terrestrial organisms by oil extraction industry in ogale, nigeria. | ogale community in rivers state, nigeria is characterized by crude-oil contamination of its land resources. the present study aimed to evaluate the health risk and metal (cd, pb, zn, cr, and ni) contamination level of the vegetable (telfairia occidentalis), snail (achatina achatina) and the catfish (clarias gariepinus) collected from ogale community. samples collected from elele alimini community, a less polluted area was used as control. oxidative damage was evaluated in tissues of snail and in ... | 2017 | 28710990 |
