Evaluation of Polyaromatic Hydrocarbons and Some Trace Metals in Smoked Fish and Roasted Meat Samples Consumed in Ile-Oluji Town, Ondo State Nigeria

Abstract

This Study examine the Concentration of some Polycyclic Aromatic Hydrocarbons (PAHs)and some Trace Metals found in smoked Fishes and roasted meat consumed in Ile-Oluji Town, Ondo State, Nigeria. Samples of various smoked Fishes species and different types of roasted meat were collected from various locations within the town and analysed to quantitatively determine the PAHs and some Trace Metal concentrations in the samples. The results Shows the presence: of  Naphthalene  0.2187 mg/kg  to 0.4359 mg/kg  ; Phenanthrene, 0.5269 mg/kg  to 1.0884 mg/kg  ; Anthracene 0.0753 mg/kg  to 0.2364 mg/kg ;Fluoranthene 0.1345 mg/kg  to 0.2890 mg/kg; Pyrene 0.1070 mg/kg  to 0.2179 mg/kg and Acenaphthylene  0.5486 mg/kg in the smoked fish  while  concentration of Targeted PAHs in roasted meat samples were Naphthalene 0.02654 mg/kg to 0.0657 mg/kg ; Phenanthrene, 0.4671 mg/kg  to 1..1231 mg/kg and  Acenaphthylene 0.1431 mg/kg  to 0.1711 mg/kg ..Mean concentrations of Trace metals present in smoked fish were Cr, 0.8910 mg/kg to 1.7455 mg/kg; Mn, 2.1704 mg/kg to 2.4236 mg/kg; Fe, 60.0258 mg/kg to 66.4191 mg/kg; Cu, 2.0594 mg/kg to 4.8527 mg/kg ; Zn, 10.3087 mg/kg to  11.6231 mg/kg, and Cd, 0.0075 mg/kg while  concentration of Trace metals in roasted meat samples were Cr, 0.3638 mg/kg to 1.9971 mg/kg; Mn, 1.7850 mg/kg to 4.1278 mg/kg; Fe, 53.8760 mg/kg to 220.201mg/kg mg/kg; Cu, 1.0592 mg/kg to 1.7051 mg/kg ; Zn, 3.7492 mg/kg to  39.6975 mg/kg, and Pb, 0.0714 mg/kg  The results reveals the presence of  Polycyclic Aromatic Hydrocarbons  and Trace Metals in the samples, while some had  concentration below WHO/EU acceptable limits, some are above WHO /EU acceptable limits and can pose a health risk to consumers.
