Recently, there has been an increase in studies focusingon an emerging class of organic contaminants, hydroxylatedPCBs (OH-PCBs) and chlorinated phenolic compounds(CPCs) in the environment, particularly in northern regionsof Europe and Canada. Since information for fish fromthe Great Lakes are scarce, we determined the blood plasmaconcentrations of OH-PCB congeners, pentachlorophenol(PCP), 2,3,4,5-tetrachlorophenol (TCP), and 4-hydroxyheptachlorostyrene (4-OH-HpCS) for lake trout (Savelinusnamaycush) collected from two of the Great Lakes, LakeOntario and Lake Superior, and two regional lakes, LakeChamplain and Lake Opeongo. PCP was the dominant CPCin lake trout (105-658 pg/g of plasma). Detectableconcentrations of 2,3,4,5-TCP and 4-OH-HpCS were foundin all lake trout (2.6-101 and 0.4-27 pg/g, respectively).Highest concentrations were found in trout from Lake Ontarioand Lake Superior. Sixteen OH-PCBs were quantified,with 4-OH-CB187 having the highest concentration in allsamples (10-173 pg/g of plasma). Unexpectedly, highlychlorinated OH-PCBs such as 4'-OH-CB199 (mean 21.4 and74.4 pg/g), 4,4'-diOH-CB202 (18.3 and 27.7 pg/g), and 4'-OH-CB208 (24.5 and 34.7 pg/g) were found in lake troutfrom Lake Ontario and Lake Superior, respectively. Futurestudies to delineate the sources and impacts of CPCs inthe Great Lakes catchment are needed.
