Exhaustive Steam Distillation Extraction of Aromatic Organics from Rainbow Trout and Water
Abstract
Exhaustive steam distillation extracted several intermediate molecular weight organic
chemicals effectively from rainbow trout, but a high molecular weight organic, benzo[a]pyrene,
was not extracted. Fish lipids that do not steam-distill appear to retain extremely lipophilic organics
in the boiling flask. Therefore, exhaustive steam distillation should be used cautiously in screen-
ing effluents for chemicals that are bioaccumulated.
Keywords-Phenol, Naphthalene, Anthracene, Benzo[a]pyrene, Salmo gairdneri
