70 blood samples - collected in 1993 in Germany - have been analysed f
or PCDD/PCDF. For all persons involved, no certain expose, except for
food consumption, has been reported. The levels measured show a decrea
se of PCDD/PCDF compared to previous data on blood collected mainly in
1989 and in 1992. This trend for the dioxin values in blood correspon
ds well to the observations reported for human milk.
