Abstract niet beschikbaar
Since February 1990, dioxin levels are measured in cow's milk from selected dairy farms in the neighbourhood of dioxin sources like municipal waste incinerators (MWIs) and metal reclamation plants. Levels are expressed in picograms 2,3,7,8-TCDD toxicity equivalents (TEQ) per gram of milk fat, calculated on the basis of international toxicity equivalence factors (I-TEFs) of the individual congeners. This report presents the results of the measurements in samples of cow's milk from three dairy farms near the MWI of Rotterdam (the Lickebaert area), the Netherlands. These samples were collected in the period of April to June 1993. Dioxin levels ranges from 3.6 to 8.3 pg TEQ/g of fat. A decline is observed in this period. Levels decreased to a level between 3.6 and 5.8 pg TEQ/g of fat in June 1993, which is below the Dutch legislation level for dioxins in cow's milk (6 pg TEQ/g of fat). A similar time course had been observed in 1991 and 1992.
