Persistent Effects In White-Tailed Eagle
From suffering the highest concentrations of toxic pollutants among birds of prey in the world, white-tailed eagle living along the Baltic Sea now have clearly lower levels of PCB and DDT. It is still possible to show residual effects in some birds according to new Swedish findings. Female birds born during the worst years in the 1960s and 1970s have inferior eggs than other white-tailed eagles. Fewer eggs are hatched and some show no foetal development at all. The phsyiological reasons for these defects are still not known.

Toxic Pollutants In The Blood Of Inuits - N.B. Human Exposure II
Wednesday
afternoon (2 - 5 p.m.)
A Canadian study shows that Inuits who largely live on fatty fish contaminated with organic pollutants have high levels of OH-PCBs, reaction products of PCB which are retained in the blood. Concentrations in the blood are on average 30 times higher than in other populations (control group), but levels of up to 100 times higher than "normal" can occur. This is the first study to link levels of OH-PCB to age, indicating primarily a relation between PCB levels and age. OH-PCBs are suspected to be hormone disrupting.EpidemiologyAnalysis Of Hydroxylated Metabolites Of PCBs In Whole Blood From Canadian Inuit
