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 · 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.
