Dietary intake of PCDD/F by small children with different food consumption measured by the duplicate method

The dietary intake of PCDD/F by 42 small children, 21 boys and 21 girls in the age range 14-47 months, with different food consumption behaviour living in urban and rural areas of Germany was measured by the duplicate method with a 7 day sampling period from May to September 1998. The PCDD/F-levels in the food duplicates were in the range 39.2-325 fg I-TEq/g(dry weight) (median: 90.7; arithmetic mean: 96.6) and the doses were in the range 0.681-5.43 with a median of 1.56 and an arithmetic mean (AM) of 1.60 pg I-TEq/(kg(body weight) x d). Children living in an urban industrialized area with food consumption including products from the family owned vegetable gardens or the surrounding area and/or products from domestic animals showed no statistically significant different concentrations in the food duplicates or in the dietary intake of PCDD/F, calculated as I-TEq, than children living in a rural area with similar food consumption behavior or than children consuming exclusively food from the supermarket.
