English Abstract This report describes the results of the analysis of
dioxins in meat, organs and fat tissue of one cow, one sheep and four bulls
from farms in the Lickebaert area in the vicinity of the waste incinerator
Rijnmond (AVR) near Rotterdam and of three sheep which lived within 500m of
a metal reclamation plant near Culemborg, the Netherlands. Dioxin levels in
the fat of all animals were found to be increased when compared to the Dutch
background level in milk fat. Levels ranged from 6.1+-0.3 in a bull to
18.0+-0.9 pg 2,3,7,8-TCDD equivalents g-1 of fat in one sheep. Levels of
dioxins on fat basis were very close in different fat compartments and were
also in good agreement with the level in milk fat. Fat levels in animals
slaughtered in winter were not significantly different when compared to the
summer period for animals which had been fed with hay or other grass
products grown on the land of the same dairy farm or obtained from other
fields in that area. In general, levels found in sheep were higher than in
cows.
