Determination of Concentrations of Some Toxic Heavy Metals (Cr, Cd and Pb) in Cow�??s Milk Using Simultaneous Atomic Fluorescence Spectrometer

Azanaw Girmaw

Heavy metals are considered as the most important contaminations due to the industrialization of countries and have the influence on its existence in milk and milk products. In this study, milk samples were taken from a small household around Debre Tabor Town for determination concentration of Cr, Cd and Pb using AF420. The data obtained as such were subjected to one way ANOVA using Duncan’s multiple range tests. The overall mean concentrations of Cd and Cr in all samples were 92.7 ± 0.07 and 54.3 ± 0.01 µg/L respectively whereas concentration of Pb was below detection limit. Significant differences were not observed among the two different days in the sampled cows’ milk with respect to their elemental contents.
