Abstract
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.
