Abstract

Retention times of 34 (Br2‐Br7) 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.
