HEALTH RISK ASSESSMENT OF SELECTED TRACE ELEMENTS IN CANNED FISH SOLD IN BENIN CITY, EDO STATE, NIGERIA

Authors: *Erhunmwunse N.O, Tongo I

ABSTRACT

In this study, the level of heavy metals in selected readily consumed canned fish obtained from Benin metropolis, Edo State, Nigeria were determined using BUCK 210 VGP Atomic Absorption Spectrophotometer, while human health risk was estimated using standard risk assessment indices. The level of Nickel (Ni) ranged from 2.25±0.41to 4.03±0.11mg/kg, while Manganese (Mn) ranged from 3.25 ± 0.10 to 7.75 ±0.30 mg/kg, Cadmium (Cd) and Lead (Pb) ranged from 0.00±0.00 to 0.82±0.06 mg/kg and 0.34±0.12 to 1.87±0.47mg/kg respectively. Copper (Cu) ranged from 0.25±0.15 to 7.75±0.51 mg/kg, Iron (Fe) ranged from 6.21±0.31 to 16.21±0.50 mg/kg and Zinc (Zn) ranged from 2.02±0.91to 9.46±0.42 mg/kg. Fe, Zn, Cu and Pb were found to be significant (P<0.05) while Mn and Cd were found to be non-significant. Recoveries of the trace elements were in the range of 89.5 ± 1.45 to 98.7 ± 3.12%. Risk estimates show that the estimated daily intakes in the examined samples were below the FAO/WHO 2006 Guidelines limits while Target Hazard Quotients (THQ) and Hazard Index (HI) were less than one for all metals considered. The results of this study indicate that no considerable health risk could arise from the consumption of selected canned fish readily available in Benin Metropolis.
