Dietary intake of platinum and gold by children from Germany using duplicate portion sampling.

The dietary intake of platinum and gold by 84 small children, 42 boys and 42 girls at the age of 14 to 83 months, with different food consumption behaviour living in urban and rural areas of Germany was measured by the duplicate method with a seven day sampling period from May to September 1998. The levels in the food duplicates were in the range of <0.01 to 450 ng Pt/kg dry weight (median: 22) and <0.14 to 28 μg Au/kg dry weight (median: 0.645). Related to the body weight, Pt was in the range of <0.81 to 32 ng/(kg body weight · week) (median: 2.3) and Au was <0.015 to 2.6 μg/(kg body weight · week) (median: 0.068).
