The objectives of this study are to determine the concentration of heavy metals in selected organs of free range chicken and ascertain the human health risk implications via consumption. Samples of free range chicken around the study areas were purchased from their owners. Heavy metal concentrations were analysed in tissues using Buck scientific atomic absorption spectrophotometer, model 210VGP. The results revealed that the heavy metal contents were not significant (P >0.05 and P>0.01) in all selected organs and across the locations sampled. The results of the target hazard quotient (THQ) were less than 1 for all single metals found in the each organ from all locations. The highest THQ (1.04) was in the spleen sourced from Ekweniro at January 2017. The total target hazard quotient (TTHQ) obtained in the various organ parts of the free range chicken might contribute to the potential health risk if consumed in large proportion simultaneously or differently. All the Estimated daily intake (EDI) values obtained in this study ranged from 0.00 to 0.10 mg/kg. The computed values of the ?I to provisional tolerable daily intake (PTDI), showed that Ni in the muscles, crop and gizzard were 0.60 and 0.49%, while the liver, intestine and spleen were 0.45, 0.47 and 0.47% respectively. The findings of this study revealed that Zn, Cu and NI had great total health risk impacts (THRI) if they are consumed together. Zn and Cu had values far > 1 while the values of Ni were > 1 and < 1 respectively.
