[The lead concentration in the converted and special-formula milks used in infant feeding].

In the last years a strict correlation between chronic exposure to low lead doses and neuropsychological impairment in first childhood is often reported in literature. The authors have measured and than compared the lead content of milk-based formulas, of special-formulas (hypoallergenic-protein formulas, lactose-free formulas, proteic-hydrolysate formulas) and soya formulas. 20 samples of milk-based formula, have been measured along with, 22 samples of special formula and 14 samples of soya formula. Lead mean concentration in milk-based formula was 73 +/- 139.11 microgr./l, whereas 23.95 +/- 13.76 microgr./l and 22.57 +/- 13.42 were measured in special formula and soya formula respectively. These results were compared with Student t-test and no significative difference was found. Lead mean concentration of milk-based formula was higher than that of special formula or soya formula. The authors hope milk-formula industry to have a more specific control on lead milk content for children feeding. In order to avoid possible toxic injuries in little infants, industry should certainly pay more attention both in supplying and in technological management of milk.
