A major impact of marine pollution is the contamination of fish, which has become an issue of concern due to the potential adverse human health effects. Therefore, this study assessed heavy metal (Cu, Ni, Fe, Cd, Pb, Zn and Hg) concentrations in different parts of five fish species namely S. aurita, E. encrasicolus, S. colias, B. auritus and P. bellottii from the Gulf of Guinea and their implications for human health. The results showed that Cd and Pb concentrations in all the analysed fish species were below their respective detection limits of 0.01 mg kg⁻¹ dw and 0.05 mg kg⁻¹ dw and thus pose low health risks. On a wet weight basis, the mean metal concentrations in fish muscle ranged from 0.04 to 0.31 mg kg⁻¹ for Cu, 1.23 to 3.87 mg kg⁻¹ for Fe, 0.20 to 0.39 mg kg⁻¹ for Ni, 0.17 to 0.42 for Zn, and 0 to 0.05 mg kg⁻¹ for Hg. Although these measured metal concentrations were within permissible limits for human consumption, the calculated hazard quotients indicated that the concentrations of Hg in S. aurita, S. colias and B. auritus pose significant health risks.

海洋污染的主要影响是鱼的污染，由于对人类健康的潜在不利影响，这已成为一个令人关注的问题。因此，本研究评估重金属（铜，镍，铁，镉，铅，锌和汞）的浓度以5种鱼类即不同部分S. aurita，E. encrasicolus，S.豆粉蝶属，B. auritus和P. bellottii来自几内亚湾及其对人类健康的影响。结果表明，所有分析鱼种中的Cd和Pb浓度均低于其各自的检出限0.01 mg kg ^-1 dw和0.05 mg kg ^-1dw，因此对健康的危害很小。上的湿重的基础上，在鱼肌肉的平均金属浓度范围为0.04至0.31毫克千克^-1对Cu，1.23〜3.87毫克千克^-1为铁，0.20〜0.39毫克千克^-1为镍，0.17至0.42的Zn为，汞的含量为0至0.05 mg kg ^-1。虽然这些测定金属浓度分别为供人类食用容许的限度内，所计算出的危险的商表示，汞的浓度S. aurita，S.豆粉蝶属和B. auritus构成显著健康风险。
