Abstract
Three types of woods were investigated; hard wood HWS Mahogany (Mellicae), soft wood SWS Bamboo (Mycapella) and oil palm wood PWS Elaeis guineensis to smoke African catfish Clarias gariepinus. The Polycyclic Aromatic Hydrocarbons (PAHs) in the experimental fish were extracted using solvents and Ultrasonication and were analyzed for 15 Polycyclic Aromatic Hydrocarbons using high performance liquid chromatography (HPLC) with ultraviolet diode detector. There was no significant difference between the three woods investigated (P > 0.05) in benzo_b fluoranthene and benzo_a pyrene but significant differences (P < 0.05) in PAH occurred between the 3 wood-smoked fish in acenaphthene, fluorine, phenathrene, anthracene, pyrene, dibenzo_ah anthracene, benzo_ghi pyrene, indeno 123c pyrene, fluoranthene with lowest value in PWS. Naphthalene and acenaphthylene had same value in HWS and SWS but were significantly lower in PWS. Conversely, benz_a athracene showed higher value in HWS compared to SWS and PWS but chrysene displayed higher value in SWS compared to PWS and HWS. It can be concluded that the use of Elaeis guineensis is preferred in smoking of C. gariepinus compared to Bamboo and Mahogany. Since the three woods did not differ in benzo a pyrene, high value of benz_a anthracene recorded in HWS fell below carcinogenic ranges, hence usage may not impact on human health.
