Bioconcentration of Polychlorinated Bornanes Toxaphene

It is important to note that some polychlorinated bornanes are very persistent to biodegradation and are bio concentrated in the fatty tissue of fish [227] and other aquatic organisms. In marine fish and other aquatic organisms, such as seals, whales, and penguin 2-endo,3-exo,5-endo,6-exo,8b,8c,10a,10b-octachlorobornane (Parlar No. 26, B8-1413, Tox8) and 2-endo, 3-exo,5-endo,6-exo,8b,8c,9c,10a,10c-nonachlorobornane (Parlar No. 50,B9-1679, Tox9, Toxicant Ac) are dominant [221 -223]. Furthermore, other persistent chlorinated bornanes are 2-exo,3-endo,5-exo,9b,9c,10a,10b-heptachlorobornane (Tox7, B7-1453), 2-
