Determination of 40 Elements in Powdered Infant Formulas and Related Risk Assessment

The aim of the study was to analyze all powdered infant formulas authorized and commercialized in Italy at the time of the study to measure the concentrations of 40 elements, and to estimate the infants' intake of some toxic heavy metals for assessing possible related health risks. For this purpose, an optimized multi-element method was used through inductively coupled plasma mass spectrometry. Be, B, Al, Zr, Nb, Sb, Te, W, V, Cr and As concentrations were -1 for Ca and K or less than 1 ng g^-1 for others). The results were similar to those reported by other European Union (EU) studies, but different from those recovered outside the EU. These differences should be eliminated to guarantee the right to health worldwide. The concentrations of Cd, Mn, Ni, Pb, and Zn in the infant formulas studied were always below the considered limits. However, it is important to check for potentially toxic elements in infant formulas to protect the health of this sensitive population. The data found in this study could be used as benchmark data for future research.
