Estimation of Aluminum Level in Locally Packaged Milk Powder

Abstract

This study was conducted to estimate Aluminum level (Al) in locally packaged milk powder, discussing its public health effect and suggesting recommendations to avoid such contamination. Therefore, fifty random samples of locally packaged milk powder were collected from different markets and pharmacies in Assiut Governorate, Egypt. These samples were digested and Al levels were estimated using HR-CS (High Resolution Continuum Source Atomic Absorption Spectrophotometer) and compared with Maximum Permissible Limit (MPL). About 96% of milk powder samples were containing Al with an average value of 0.086 mg/L and fortunately were lower than MPL. The present study revealed that milk powder contains aluminum element in variable concentrations above the toxicity levels. Therefore, to lower aluminum content, it is important to avoid the sources of contamination.
