In
samples of Baltic herring WHO-TEQPCB on 2-3 times higher then WHO-TEQPCDD/F, this ratio is higher than found earlier for herring caught in 1993-1994 and 1999 in
Finland and
Bothnia gulfs, but concentration on PCBs are in the same range, and generally data are not in
contradiction.
In
smoked eel PCBs are brought the basic contribution to the total toxicity. Most likely it is connected
with eel's high ability to bioaccumulation of PCBs contained in sediments as
has been shown
previously.
