RESUMO
Daily intakes of essential minerals and metallic micro-pollutants are estimated from foods usually eaten in France. These foods are grouped in nine categories. For essential elements, intake estimates are comparable to the values recommended by the WHO. The cadmium value is lower than the tolerable daily dose. The estimated values are: cobalt 29 micrograms/day, chromium 98 microgram/day, copper 1.5 mg/day, manganese 2.5 mg/day, molybdenum 275 micrograms/day, zinc 14 microgram/day, aluminium 4.2 mg/day, boron 1.6 mg/day, cadmium 27 micrograms/day and nickel 231 microgram/day.

The tin contents in fresh food or in food stored in lacquered or unlacquered cans were determined in order to estimate the daily tin intake in a French citizen. Tin levels were 76.6 +/- 36.5 mg/kg in foods preserved in unlacquered cans, 3.2 +/- 2.3 mg/kg in foods stored in lacquered cans, and 0.03 +/- 0.03 mg/kg in fresh foods. Tin intake is essentially dependent on food stored in tin cans (98%), which only represents 5.6% of the total daily consumption of foods by a French citizen. The estimated tin intake (2.7 mg/day whether 0. 04 mg/kg of body weight) remains widely inferior to the daily tolerable dose in humans (2 mg/kg of body weight).

Concentrations of 11 minerals were determined in six kinds of milk (cow's milk-based formulae, breast-milk, soya milk, bottled milk, dried milk and evaporated milk). The contents of copper, magnesium, molybdenum, aluminium, barium and nickel were higher in soya milk than in any other kinds of milk. Except for nickel in soya milk, the dietary intakes of minerals were below or close to the intake recommended by the FAO/WHO.
