Abstract	Bald eagles are predatory birds, which feed at the top of the aquatic food web. Since bald eagles are relatively long-lived birds (up to 30 years in wild), they remain sensitive to environmental toxicants that bioaccumulate and affect critical biological processes such as reproduction. Regulation of the use of DDT in the early 1970s has resulted in the recovery of bald eagle populations in the USA, although, in some locations, PCBs and other chlorinated hydrocarbons continue to affect bald eagle production. Bald eagle was listed as an endangered/threatened species in the USA until 1999. Reports of PCB or DDT concentrations in bald eagle tissues such as liver, muscle, fat, kidney or gall bladder are sparse due to the difficulties in obtaining such tissues. Tissues of freshly dead bald eagles collected from the Upper Peninsula of Michigan, USA, provided an opportunity to analyze chlorinated hydrocarbons in several body tissues. Considering the lack of information on tissue-specific accumulation of PCDDs, PCDFs, dioxin-like and total PCBs, p p'-DDE and HCB, concentrations of these compounds were measured in liver, kidney, muscle, fat, blood plasma and gall bladder of bald eagle collected from the Upper Peninsula of Michigan, USA. Elimination rates of target analytes were also calculated based on the concentrations in bile/gall bladder.
