organochlorine compounds in blubber, liver and brain in neonatal grey seal pups.the present study focuses on the distribution and accumulation of persistent organochlorine compounds in different tissues and organs of grey seal (halichoerus grypus) pups. thus, levels of drins (aldrin, dieldrin, endrin), chlordanes (heptachlor, heptachlorepoxide, oxychlordane, transnonachlor), ddts (p,p'-dde, o,p'-ddd, p,p'-ddd, o,p'-ddt, p,p'-ddt) and 22 pcb congeners were determined in samples of brain, fat, and liver of 0-10 days old grey seal pups from the species' main breeding site in n ...19968653379
an overview of exposure to, and effects of, petroleum oil and organochlorine pollution in grey seals (halichoerus grypus).most incidences involving oil pollution of grey seals (halichoerus grypus) seem to have occurred at the breeding sites. because of the high concentration of animals at this time, even small oil spills will pollute many animals. as a result of chronic low-level pollution from coastal ship traffic and discharges from offshore petroleum activity in the north sea, approximately 50% of the grey seal pups at the largest breeding colony in norway are polluted each year by oil. in this case, as well as ...19968685703
current levels of ddt, pcb and trace elements in the baltic ringed seals (phoca hispida baltica) and grey seals (halichoerus grypus).residue levels of polychlorinated biphenyls (pcbs) and 1,1,1-trichloro-2,2-bis[p-chlorophenyl]ethane (ddt) were determined from liver samples of ringed seals (phoca lispida) from the baltic sea and svalbard, and of grey seals (halichoerus grypus) from the baltic sea and sable island in canada. both baltic seal populations showed clearly higher average sum pcb (spcb) and sum ddt (sddt) levels than the reference seal populations. among the baltic seals, spcb levels were twice as high as sddt level ...200212166673
