Trace elements assessment and natural radioactivity levels of infant formulas consumed in Egypt

Abstract Powder samples of infant’s milk formula from thirty four different brands commonly consumed in Egypt were collected from drug stores and local markets. The concentrations of seventeen elements (Al, Br, Ca, Cl, Co, Cu, Fe, I, K, Mg, Mn, Na, Rb, Sb, Sc, Se, and Zn) were determined by instrume...

Abstract Powder samples of infant’s milk formula from thirty four different brands commonly consumed in Egypt were collected from drug stores and local markets. The concentrations of seventeen elements (Al, Br, Ca, Cl, Co, Cu, Fe, I, K, Mg, Mn, Na, Rb, Sb, Sc, Se, and Zn) were determined by instrumental neutron activation analysis. The results reveal that the infants’ milk provides adequate amounts of most essential elements; and considered as a suitable source of nutrient for infants during their early life stages. The activity concentrations of 226Ra, 232Th and 40K were measured and used to estimate the radiation hazard indices. Ausführliche Beschreibung
