Quantitative Assessment of Polycyclic Aromatic Hydrocarbons and Heavy Metals in Fish Roasted with Firewood, Waste Tyres and Polyethylene Materials

Ujowundu CO Ogbede JU¹

Abstract: The bioaccumulation and biomagnification of PAHs along successive trophic levels is an important means of exposure to human and animal life. This study evaluated Polycyclic Aromatic Hydrocarbons (PAHs) and heavy metals in fresh fish and fish samples processed/ roasted with smoke/heat/flame generated from firewood, waste tyre and polyethylene materials. PAHs and heavy metals were determined with Gas chromatography with flame ionization detector (GC-FID) and Atomic Absorption Spectrophotometer (AAS) respectively… Show more

Background and Objective: Hydrocarbon extraction activities along the coastlines of the Niger Delta are rife for decades and have contributed to various categories of persistent pollutants in the aquatic ecosystem. The bioaccumulation and induction of some biochemical markers in the blue crab, Callinectes sapidus as indicators of chronic petrogenic pollutions was studied. Materials and Methods: In situ, measurements for water temperature, pH, electrical conductivity, salinity, total dissolved solids and dissolved oxygen were made at the sampling locations. Forty-eight female crabs (weight 149.2±0.02 g) were harvested with a 15 mm mesh size fishing net and taken to the laboratory in plastic containers filled with their habitat water for the estimation of biomarker levels. Results: Tissue accumulations of the Polynuclear Aromatic Hydrocarbons (PAHs) at OSD ranged from 0.02-0.09 μg gG 1 and Mononuclear Aromatic Hydrocarbons (MAHs) from 0.01-0.02 μg gG 1 , but were 0.01 μg gG 1 and undetected in tissues at ISD. The levels of Alanine Aminotransferase (ALT) (sig. = 0.032), Aspartate Aminotransferase (AST) (sig. = 0.045), Alkaline Phosphatase (ALP) (sig. = 0.007), total proteins (sig. = 0.036) and malondialdehyde (MDA) (sig. = 0.005) were all markedly higher at the OSD location at the 95% confidence limit. The ordination biplot revealed that the explained variations for axes 1 and 2 were 68.95 and 85.38% and the eigenvalues were 0.689 and 0.164, respectively. The multivariate pie classes showed that the largest sector for AST was OSD 2, MDA and ALT were OSD 1 and ALP was OSD 3. Elevated PAHs and MAHs appeared to induce the production of more ALP (r = 0.695 and 0.660, respectively, p<0.05) and PAHs alone induced the production of more proteins (r = 0.630 and p<0.05). Conclusion: It was confirmed that allocthonous input of petroleum pollutants in aquatic ecosystems could cause biological disruptions, including tissue bioaccumulation and other biochemical disruptions in proteins and enzyme activities.

This study investigated the oxidative modulation potentials of diets supplemented with Solanum lycopersicum and Allium cepa against biochemical changes initiated in rats fed diet prepared with fish smoked with polyethylene material (FSP) and fish smoked with firewood (FSF). Thirty male Wistar albino rats were randomly grouped into six with five rats in each group. The biochemical parameters analyzed indicated significant (p < 0.05) increases in the activities of liver enzymes [alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST)] and concentration of total bilirubin and malondialdehyde (MDA) in rats maintained on diets prepared with FSF and FSP only when compared to rats maintained on rats pellets only and rats maintained on the supplemented diets. These groups of rats also presented significant (p < 0.05) fluctuations in activities of glutathione peroxidise (GPx), superoxide dismutase (SOD) and catalase (CAT) and concentrations of total protein, albumin, total cholesterol and glutathione (GSH). However, the S. lycopersicum and A. cepa treated groups showed significant restoration towards their respective normal control values. These results indicate that smoking as a food processing method (especially using polyethylene materials) generates oxidants that may induce oxidative damage. The antioxidative role of A. cepa and S. lycopersicum in the diets of treated animals emphasized their hepatoprotective potentials.
