Year Dietary intake (µg/kg body weight per day)
Adult Toddler Infants
a ATSDR (2000). Estimated intakes are based on an average "total diet" composition (which varies slightly) and not on individual food items. Average body weights are assumed to be 9 kg for infants, 13 kg for toddlers, and 70 kg for adults. Accordingly, the average dietary intake for 1982–1984 would be 0.0108 µg, 0.0104 μg, and 0.035 μg for the infant, toddler, and adult, respectively.
