Abstract

Three environmentally significant chlorinated bornane (CHB) congeners were extracted from Arviat ringed seal blubber and identified by using gas chromatography/mass spectrometry (HRGC/HRECNIMS (CH₄), low resolution EIMS, and linked field scanning). They are referred to as TS2 (Parlar 39, B8-531) [2-exo,3-endo,5-exo,6,6,8b,9c,10c (or 10a)-octachlorobornane], TS3 (Parlar 40, B8-1414) [2-endo,3-exo,5-endo,6-exo,8c,9b,10a,10c (or 10b)-octachlorobornane] and TS4 (Parlar 42, Toxicant A, B8-806/809) [2-exo,3-endo,6,6,8b,8c,9c,10c (or 10a)-octachlorobornane/2-exo,3-endo,6,6,8b,9b,9c,10a (or 10b)-octachlorobornane]. This is the first time Toxicant A, known to be the most toxic CHB congener in technical toxaphene, has been found in any significant concentration in a marine mammal.
