Age and accumulation of persistent organochlorines: A study of arctic‐breeding glaucous gulls ( Larus hyperboreus )
Abstract We studied the relationship between increasing age and blood concentrations of four persistent organochlorines (OCs), hexachlorbenzene (HCB), oxychlordane, p,p ′‐dichlorodiphenyldichloroethylene (DDE), and 2,2′,4,4′,5,5′‐hexachlorbiphenyl (PCB‐153), in arctic‐breeding glaucous gulls ( Larus...

In areas in which birds fed on prey from higher trophic levels, the OC concentrations showed large increases between sampling events; in areas in which birds fed at lower trophic levels, OC concentrations increased relatively little or not at all.

Changes in body condition and amount of blood lipids were of lesser importance than trophic level and influenced the concentrations of HCB and oxychlordane more strongly than DDE and PCB‐153. In conclusion, this study indicates that steady‐state concentrations of persistent OCs are reached early in life in most glaucous gulls, considering the long life span of the species.
