Abstract
Food safety issues and potential health risks in avian tissues are one of the most
serious environmental concerns, this paper carries out probabilistic risk analysis methods
to quantify trace elements bioaccumulation in chicken liver, gizzard, and lung content to
assess the range of exposures for the people who consume the contaminated chicken. The
concentrations of Al (aluminum), Mn (manganese), Cu (copper), Co (cobalt), and Zn
(zinc) were measured using inductively coupled plasma mass spectrometry (ICP-MS),
using the stock standard solution of heavy metals and blank sample. Results show the
contents of elements in bird tissues samples were in the range of (18.68-62.24, 1.6-18.6,
0.12-0.61, 2.12-24.95, 35.10-93.85 µg/g for Al, Mn, Co, Cu, and Zn respectively. A risk
assessment on human health beings due to consumption of chicken was performed using
toxic reference benchmark, namely the reference dose (RfD). The hazard index (HI), sum
of the hazard quotients calculated for all pollutants have shown that the risks of fowls
consumption were generally low and are within safe limits.
