ABSTRACT
Infant formula foods, such as evaporated milk, modified milk, and formulas containing lamb meat and soya flour, were collected quarterly from the Cincinnati, Ohio, market. Human milk from 13 mothers residing in the cincinnati area was collected during April and May 1968. They were analyzed for Cd, Cu, Fe, Pb, Mn, and Zn by atomic absorption spectrophotometry. Averaged elements in various formulas including evaporated milk and human milk as ppm were: Cd, 0.020 to 0.042; Cu, 0.024 to 1.49; Fe, 0.84 to 19.1; Pb, 0.012 to 0.87; Mn, 0.12 to 2.68; and Zn, 1.34 to 8.60. Human milk and formulas containing milk base had least Cd, Cu, Mn, and Pb; evaporated milk, however, had the most Pb. Formulas containing soya flour and lamb meat products were high in trace elements.
