The body distribution and incorporation into complex lipids of C-14 from orally administered, radiolabelled dichlorostearic, stearic and oleic acid were studied in perch, Perca fluviatilis. Uptake and incorporation of C-14 from radiolabelled dichlorostearic acids did not differ significantly from that of unchlorinated fatty acids, implying that dichlorostearic acid most probably was not recognised as 'abnormal'. This may distinguish chlorinated fatty acids from other known organic pollutants. High concentrations of chlorinated fatty acids in fish have been correlated with adverse biological effects and may cause disturbances in biological membranes, particularly if they become incorporated into phospholipids. Lack of recognition, and thereby elimination, of the chlorinated fatty acids by the fish may impose an increased risk for toxic effects.
