“…Were taken in a conical flask in which 10mL and 1mL were added of HNO 3 and H 2 O 2 concentrations, respectively, after 20 min repeats the heating process once more with the same procedure. This mixture was digested in a Microwave digester for 45-50 minutes (Sai Chaithanya et al, 2022). The mixture should cool down and then dissolve in deionized water until it has a clear solution.…”

Bioaccumulation of heavy metals occurs in a variety of tissues in food animals as a serious environmental pollutant. The present study was to examine heavy metal levels such as Iron (Fe), Mercury (Hg), Manganese (Mn), Zinc (Zn), Arsenic (As), Cobalt (Co), Chromium (Cr), and Copper (Cu) in sheep and goat liver tissue from a polluted region in northern Iraq called Kurdistan. A comparison was made between all results and World Health Organization (WHO) standard limits. In this study, forty of samples tissue were taken from the livers of Sheep (n=20) and goats (n=20) from a slaughterhouse in Erbil, Kurdistan region north of Iraq. The concentration of eight vital heavy metals has been targeted by performing Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) and concentrated HNO 3 and H 2 O 2 were used to dry and digest the samples. The result obtained from the study of heavy metals for instance (Mn, As, Zn, Co, and Cr) in the liver of sheep and goats is within the admissible limit recommended by World Health Organization (WHO). However, the remaining elements (Cu, Hg, and Fe) were found in danger, as they are higher than the normally accepted standards. Moreover, there is a significant difference for (Fe, Mn, Zn, Co, and Cr) and a non-significant for (Hg, As, and Cu) between the livers of sheep and goats in the study area. Variations in liver element values are likely attributable to feeding, environmental conditions, animal feed constituents, and analytical terms.
