Aluminium content of infant formulas.

An investigation was undertaken in order to assess Al concentration levels in infant formulas. Eligibility criteria were defined and strictly adhered to. An overall strategy was worked out to guarantee reliability and representativity of experimental data, in particular by minimizing all possible sources of chemical contamination or loss. The study was carried out by means of Inductively-Coupled Plasma Atomic Emission Spectrometry (ICP-AES). In cow's milk-based infant formulas as made up for consumption (about 13% in the final solution), Al levels of between 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.
