The aim of this study was to determine the levels of zinc (Ln), copper {Cu), lead (Pb} and cadmium (Cd) in commercial mango fruit juices commonly sold at Buhr[ Dar 1 own, Ethiopia: Atomic absorption spectrometry was used 10 determine the levels of these mewls and four available brands were considered, namely Maaza.
