Concentration of heavy metals in two fish species (Cynoscion regalis and Pomatomus saltatrix) from an oil drilling area in Western Coast of Ghana and public health risk assessment

This study assessed heavy metals (Lead (Pb), Nickel (Ni), Iron (Fe), Chromium (Cr), and Cadmium (Cd)) concentration in water (from borehole, hand-dug well the sea) fish (Cynoscion regalis Pomatomus saltatrix species) possible health risk exposure by consumption of these fishes. A total 18 samples two species (C. P. saltatrix) were collected from Jomoro, Ellembelle Ahanta West District analyzed for Pb, Ni, Fe, Cr, Cd using Atomic Absorption Spectrometer (AAS). Results revealed appreciable concentrations Fe muscle water. Cr not detected samples. Heavy increased order Pb < Ni Fe. The Estimated Daily Intake value adult ranged 1.88 x 10-3 to 2.03 10-1 (mg/kg bw/day), however, those children 4.40 4.74 10-1(mg/kg bw/day). For assessment, Total Targeted Hazard Quotient adults was 1; >1 C. but less than 1 (< 1) meaning who consume are exposed their life time. results confirmed that contaminated environments could result bioaccumulation metal pollutants fish's muscle, which poses a humans when consumed. Awareness education general public on threshold crucial safeguard against risks.
