The present study was conducted to determine daily intake of cadmium (Cd), copper (Cu), and lead (Pb) and to assess noncarcinogenic human health risk caused by these trace metals in the commonly consumed fish species ( Oreochromis niloticus, Rastrineobola argentea, Lates niloticus, and Protopterus aethiopicus) in Nakuru town, Kenya. Trace metal determination in the composite samples of the commonly consumed fish species was done using flame atomic absorption spectrophotometer. Cd, Cu, and Pb content in the muscle tissues of the commonly consumed fish species ranged from 0.11 ± 0.045 to 1.11 ± 0.931 mg kg−1 for Cd, 0.48 ± 0.013 to 3.00 ± 0.009 mg kg−1 for Cu, and 3.42 ± 0.045 to 12.78 ± 0.108 mg kg−1 for Pb. Cu concentrations were within Food and Agriculture Organization (FAO) recommended limits for this trace metal in fish. In contrast, Cd and Pb had values above their respective permissible limits in fish. The assessment of human exposure to trace metals indicated that exposure doses of Cd and Cu were safe for fish consumers. Conversely, target hazard quotient (THQ) values of Pb suggested possible health risks for consumers of the commonly consumed fish species in Nakuru town, Kenya.

Abstract Study was carried out to determine the concentration and bioaccumulation of pesticide residues in edible fish from river Ganga, India, to assess human health risk via consumption of fish. Two commonly edible fish species bagrid catfish and common carp were collected. The n-hexane extract of the muscle tissues were characterized by gas chromatography coupled to mass spectrometry and quantified by electron capture detector for pesticide residues. Bioaccumulation factors (BAFs) in common carp of pesticides were found to be higher than those in bagrid fish. Daily exposures of pesticides for consumers via fish consumption were determined by calculating and comparing estimated daily intake (EDI) with ADI values. The EDI results in our study were insignificantly high from ADI values. Non-carcinogenic and carcinogenic risks were evaluated by Target hazard quotient (THQ) and risk ratio (R), respectively. Hazard quotients (THQ) were found to be lower than the set 1.0, inferring non-carcinogenic risk by consumption of fish from the river. Regard to contaminants carcinogenic affects the total risk ratio (R) value of pesticides were found lower than threshold of tolerable risk except of heptachlor indicating carcinogenic risk via consumption of fish. The results demonstrate that due to increased pollution in the ecosystem required more attention.
