The human health risk assessment associated with accumulation of nickel (Ni), cadmium (Cd), chromium (Cr), lead (Pb) and copper (Cu) in the tissues (gills, livers and muscles) of grey mullet (Mugil cephalus) collected from the creek in the Niger Delta region of Nigeria was investigated. Surface water, sediment and fish samples were collected and analysed from June to September 2019; estimated daily intake (EDI), target hazard quotient (THQ) and hazard index (HI) were determined. The mean concentration (mg/kg ww) of the tested metals followed the sequence: Cu (33.48 ± 15.54) > Cd (24.62 ± 12.11) > Pb (10.59 ± 9.12) > Cr (0.43 ± 0.66); while Ni was not detected in the sampled tissues. The HI for male and female (adults) are 7.612 and 7.840 respectively, while male and female (children) are 9.567 and 10.842 respectively.
研究了从尼日利亚尼日尔三角洲地区小溪中采集的灰鲻（Mugil cephalus）组织（鳃、肝和肌肉）中镍（Ni）、镉（Cd）、铬（Cr）、铅（Pb）和铜（Cu）积累与人体健康风险评估的关系。2019 年 6 月至 9 月期间采集并分析了地表水、沉积物和鱼类样本；测定了估计每日摄入量（EDI）、目标危害系数（THQ）和危害指数（HI）。测试金属的平均浓度（mg/kg ww）顺序为：Cu（33.48±15.54）>Cd（24.62±12.11）>Pb（10.59±9.12）>Cr（0.43±0.66）；而镍未在采样组织中检出。雄性和雌性（成年）的 HI 分别为 7.612 和 7.840，而雄性和雌性（儿童）的 HI 分别为 9.567 和 10.842。
