title: Use of high-performance liquid chromatography for the estimation of polychlorinated biphenyls and p,p-DDE residues in marine mammals.
abstract: We present a screening technique for the detection of polychlorinated biphenyls (PCBs) and p,p-DDE residue levels in marine mammal blubber using high-performance liquid chromatography (HPLC). This method modifies the standard extraction and clean-up methods for organochlorines for use with HPLC and uses a method of chemical derivatization to separate and semi-quantify the two organochlorines with HPLC.
