Levels Of Pcdds And Pcdfs In Human-Milk - Dependence On Several Parameters And Dietary Habits

The influence of several parameters on PCDD and PCDF levels in milk fat were studied in 41 women. A significant relation was found between age and total dioxin concentrations, confirming the accumulation of these xenobiotics in humans. In contrast to smoking habits and quetelet-index (body weight/length2), the total duration of breast-feeding of previous infants was significantly related with total dioxin concentrations in milk fat, when corrected for age. A strong relation between dioxin concentrations in milk fat and the consumption of animal, but not with vegetable, fats and proteins was found. These results indicate that consumption of animal fats plays an important role in human exposure to dioxins.
