Dietary intake of Al, Ca, Cu, Fe, Pb, and Zn in infants.

The dietary intake of six elements--Al, Ca, Cu, Fe, Pb, and Zn--was measured in 39 normal healthy children aged 17-61 (mean 35.5) weeks. There was a downward trend with age in daily intake of fluid, Pb and Fe, in contrast to an increase in solid intake, Ca and Zn throughout the study. The geometric mean total daily element intake (mg) was: Al 1.12; Ca 446; Cu 0.6; Fe 4.5; Pb 0.020; Zn 2.8. The geometric mean daily element intake (mg) from milks only was as follows: Formula milk (n = 14): Al 0.26; Ca 184; Cu 0.24; Fe 1.85; Pb 0.005; Zn 1.6. Cows' milk (n = 6): Al 0.27; Ca 384; Cu 0.04; Fe 0.21; Pb 0.004; Zn 1.3. Breast milk (n = 12): Al 0.77; Ca 116; Cu 0.15; Fe 0.38; Pb 0.012; Zn 0.4. Additionally, levels of aluminium were investigated in some packaged infant foodstuffs, including four soya milk formulae. The soya-based formulae had a mean concentration of 1.09 +/- 0.37 micrograms/g, which was not significantly different from the mean of 0.83 +/- 0.28 microgram/g for six cows' milk formulae.

Perinatal lead and cadmium burden in a British urban population.

Concentrations of the potential pollutants, lead and cadmium, were studied in the perinatal period in a British urban population. Blood lead and cadmium concentrations and iron status were measured in 28 mother and infant pairs at delivery and at five days postpartum in the mother; breast milk collected at five days postpartum under controlled conditions was analysed for lead and cadmium. Placental transfer of both metals was noted; concentrations of lead in breast milk (mean concentration 0.01 mmol/l (2 micrograms/l) were less than in two brands of commercial prepacked formulas, and the concentration of cadmium in breast milk and prepacked formulas (mean 3.6 nmol/l (0.4 microgram/l] were similar. The risk of excess lead or cadmium intake from breast milk is small.

Significance of high soil lead concentrations for childhood lead burdens.

The lead exposure of children and their mothers has been studied in two towns with mean soil lead contents of 900 and 400 ppm. No significant difference in blood or fecal lead contents was demonstrated between the two populations, but a small difference in hair lead content was shown. The blood lead content of children was greater than that of their mothers and was higher in the summer than in the spring samples. Children with pica for soil in the control area had increased lead content of blood and hair. Preliminary data for children and mothers from villages with mean soil lead contents of 500 ppm and 10,000 ppm are reported which show significant differences in blood and hair lead content within the normal range. The data suggest that soil lead content of 10,000 ppm may result in increased absorption of lead in children, but to a degree which is unlikely to be of biological significance.
