BIOACCUMULATIN OF TRACE ELEMENTS IN TISSUES OF CHICKEN AND QUAIL AND ESTIMATE HEALTH RISKS FROM THE CONSUMPTION OF BIRDS VISCERA

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.
