Dialysis with a low-density polyethylene semipermeable membrane (SPM) is an efficient means of removal of lipids in the determination of bioaccumulative, persistent, halogenated organic compounds. In this study an SPM was used for preconcentration of polybrominated diphenyl ethers (PBDE) from food samples. The method is useful for determination of PBDE and other halogenated persistent organic pollutants in fatty food samples. In this work chocolate, butter, chicken eggs, pork, and salmon fat were analyzed. Lipid carry-over values (%LC) are reported and recovery of the analytes for the whole procedure was determined by fortifying fish fat with six natural PBDE internal standards which were normally present in the sample at levels below the limit of detection.
