Determination of copper, zinc, lead and cadmium in chicken liver by atomic absorption spectroscopy
Abstract
Animal liver is a storage organ for many important nutrients (vitamins A, D, E, K, B12 and minerals such as copper and zinc). However, liver also might contain higher amounts of heavy metals such as lead, cadmium and arsenic which tend to accumulate in liver tissues. This study was conducted to determine the content of copper, zinc, lead and cadmium in chicken liver samples. The samples of chicken liver were digested using wet digestion technique. Effects of several digestion parameters such as types of solvent, concentration of solvent and sample weight have been optimized. Determination of copper, zinc, lead and cadmium in chicken liver were performed by dissolving 0.5 g of the sample in 2.0M sulphuric acid and then measured directly by using flame atomic absorption spectrometer. Results showed that the concentrations of copper (2.285 -2.505 μg/g),zinc (23.450 -24.475 μg/g), lead (0.095 -0.230 μg/g)and cadmium (2.145 μg/g)in the chicken liver samples. It is proven that chicken liver contain trace metals which are essential for the body as well as heavy metals which are toxic.
