Retention times of 34 (Br 2 ‐Br 7 ) polybrominated diphenyl ether (PBDE) congeners on 30 m 5%‐diphenyl‐95%‐dimethylsiloxane type columns were compared to 131 commonly observed PCB congeners and 26 organochlorine pesticides (OCs). Results from this study indicated that there is a potential for co‐elution of 10 PBDE congeners, OCs and PCBs. Of particular concern is the inference of 2,2′,4,4′, tetrabromo diphenyl ether (BDE‐47), a predominant PBDE congener, with biologically significant PCB congener, CB‐180. Such interference was recently observed in mountain white fish ( Prosopium williamsoni ) samples collected from Wapiti River in Alberta, Canada, as is illustrated here.
