The Finnish and Russian animal species (semi-domesticated reindeer,
Finnish wild moose, Baltic grey seal and Baltic herring) samples were
biomonitored in terrestrial and aquatic environments for polychlorinated
dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated
biphenyls (PCBs) and polybrominated diphenylethers (PBDEs).
Results: Grey seal (Halichoerus grypus) was clearly the most contaminated species. The mean PBDE concentration in grey seal was 115 ng/g fat, and the highest WHO-PCDD/F-PCB-TEQ (toxic equivalent set by WHO) was 327 pg/g fat.
In Finnish, reindeer WHO-PCDD/F-TEQ varied from 0.92 pg/g fat in muscle to 90.8 pg/g fat in liver. WHO-PCDD/F-TEQ in moose liver samples was in the range of 0.7–4.26 pg/g fat, and WHO-PCB-TEQ in the range of 0.42–3.34 pg/g fat.
Overall moose had clearly lower PCDD/F and DL-PCB concentrations in their liver than reindeer.
Conclusions: Terrestrial animals generally had low POP concentrations, but in reindeer liver dioxin levels were quite high. All Finnish and Russian reindeer liver samples exceeded the EU maximum level 8 for PCDD/Fs (10 pg/g fat), which is currently set for bovine animals.
