The uterine horns in about 40 percent of a sample of ringed seal females from the Bothnian Bay were closed by stenosis and occlusions. In females showing these pathological changes, the levels of DDT and PCB substances were significantly higher than in normal, pregnant specimens. Stenosis and occlusions were also found among grey and harbor seal from Swedish waters. The levels of DDT och PCB substances in males, but not in females, were significantly correlated to age. The organochlorine levels were somewhat lower in fetuses than in the pregnant females.
