ABSTRACT
Comparative study on the risk assessment of polycyclic aromatic hydrocarbons (PAHs) content in the roasted muscle of free-lance and broilers chicken in Akwa Ibom State Nigeriawere carried out using standard analytical methods as described by USEPA,2010. The result obtained for the Risk Assessment of PAHs content in the roasted muscle of freelance were; anthracene; 0.0670mg/kg, Pyrene; 0.5383mg/kg, Benzo(a) Anthracene; 4.1784mg/kg, Chrysene; 0.2188mg/kg, Benzo(k) fluranthene; 0.1443mg/kg, Benzo(a) Pyrene; 0.0478mg/kg, Benzo (g,h,i) Pyrene; 0.6318mg/kg, Diabenz(a,h) anthracene; 0.5664mg/kg and Indeno(1,2,3-cd) Pyrene; 0.9990mg/kg. The result for roasted muscle of the broilers chicken were; anthracene; 0.0509mg/kg, Pyrene; 0.0007mg/kg, Benz(a) anthracene; 0.0032mg/kg, Chrysene; 0.0309mg/kg, Benzo(k) flouranthene; 0.0018mg/kg, Benzo(a) Pyrene; 0.0609mg/kg, Benzo(g,h,i) Pyrene; 0.0483mg/kg, Dibenz(a,h) anthracene; 0.0794mg/kg and indeno(1,2,3-cd) Pyrene; 0.0039mg/kg. The concentration of Pyrene, benz(a), anthracene, benzo(g,h,i) Pyrene, Dibenzo(a,b) anthracene and indeno(1,2,3-cd)Pyrene were higher in roasted freelance chicken than the European Union Standard Limit. The correlation analysis shows a positive strong correlation at P<0.01 as follows : Anthr/Py (r = 0.950546), Anthr/Chry (r = 0.79307), Py/Chry (r = 0.943036), B(a)A/Chry (r = 0.87532), Anthr/B(f)F (r =0.82591), Py/B(f)F (r=0.960178), Chry/B(f)F (r =0.998433), Py/B(g,h,i)P (r=0.810799), Chry/B(g,h,i)P (r = 0.959345), B(f)F/B(g,h,i)P (r=0.942045), Anthr/D(a,h)A (r=0.819004), Py/D(a,h)A (r =0.956711), While there was a negative correlation between Anthra/B(A)P(-0.73645) at P<0.01. This correlation shows that as the potential risk of anthracene increases, the potential risk of B(a)P decreases. The research shows that there is risk in consumption of roasted muscle of freelance chicken than roasted muscle of broilers chicken.
