An investigation was undertaken in order to assess Al concentration le
vels in infant formulas. Eligibility criteria were defined and strictl
y adhered to. An overall strategy was worked out to guarantee reliabil
ity and representativity of experimental data, in particular by minimi
zing all possible sources of chemical contamination or loss. The study
was carried out by means of Inductively-Coupled Plasma Atomic Emissio
n Spectrometry (ICP-AES). In cow's milk-based infant formulas as made
up for consumption (about 13% in the final solution), Al levels of bet
ween 0.03-0.85 mg/L were detected. Higher amounts were present in soya
-based formulas, with concentrations ranging from 0.39 to 1.01 mg/L.
