Toxicity Potential of Heavy Metals X-Rayed in Edible Tissues of Poultry Birds in Lafia Metropolis, Nigeria

Abstract

This study investigated the potential of human health risk associated with five heavy metals (Cr, Cd, Ni, Cu, and Pb) in edible tissues of poultry birds in the Lafia metropolis. 5 broilers, 5 Layers, and 5 local chickens  were purchased from  Alamis, Shabu, Neighborhood, and Molden markets. Nitric acid was used in the wet digestion process to prepare the samples. A flame atomic absorption spectrophotometer (FAAS) was used to measure the amounts of heavy metals in the edible tissues . In the grill sequence, the bioaccumulation tendency of heavy metals declined. Chicken tissues > layers chicken tissues > Local chicken tissues. The study revealed that the chickens have different potentials of accumulating heavy metals in their tissues with the broiler and layers chickens having the highest. The heart, intestine, and gizzard accumulated the highest concentrations of Cr, Pb, Cd, Ni, and Cu in both broilers and layers with minimal concentrations in local chickens. All of the tissues that were taken from the poultry birds were not fit for human consumption. Consuming the tissues of chicken birds carries the potential for both non-carcinogenic and carcinogenic health concerns. Poultry birds' tissues may become more heavily metal-laden due to uncontrolled leaks of hazardous heavy metals from human activity and specially prepared meals. Studies on heavy metal deposition and pollution should be carried out regularly to keep an eye on any potential health dangers to humans from consuming various bird species' tissues.
