Determination Of The Levels Of Selected Trace Heametals And Fat Content In Commercially Available Milk Brands In Addis Ababa City Ethiopia.

Six different pasteurized milk brands were analyzed for their trace heavy metals concentrationrnand fat content. The concentration of heavy metals such as Zn, Cu, Cr, Cd, Pb and Ni wasrndetermined by using flame atomic absorption spectrophotometer. The elements Cu, Cr, Cd, Pbrnand Ni were not detected in all milk brands under the study. The concentration of zinc in Etete,rnFamily, Harme, Shola, Holland and Mama milk brands were found to be 3.31± 0.671, 3.31±rn0.408, 2.12 ± 0.692, 2.26 ± 0.224, 2.42 ± 0.731 and 1.93 ± 0.382 in μg/g, respectively. There isrnno significant difference at 95% confidence interval (p > 0.05) in the mean concentrations of zincrnamong the milk brands. The results obtained for the detected element in the present study werernalso compared with European Food Safety Authority maximum permissible limit to checkrnwhether it is below or above the set limit and were found below the allowed recommended limit.rnThe validity of the digestion process was checked by recovery test. The percentage recovery ofrnzinc was found to be 98.87% which is found in the acceptable range. The fat content of eachrnmilk brand was determined and found to be 2.4%, 2.8%, 2.8%, 2.8%, 2.6% and 3% in Etete,rnFamily, Shola, Harme, Holland and Mama, respectively. The fat content of the different milkrnbrands were found to be in the order of Mama > Family = Shola = Harme >Holland > Etete. Thernanalysis of variance result showed that no significant difference was observed in the meanrnamount of fat content among all milk brands.
