title: [Multiresidue analysis of PCB, organochlorine pesticides and chlordanes in marine products by GC-micro ECD].
abstract: A multiresidue method using dual-injection, dual-column, and dual-micro electron capture detection gas chromatography (dual-column GC-µECD) was developed for the determination of PCB, organochlorine pesticides and chlordanes in marine products. The sample was extracted with hexane-acetone (2 : 1), and the extract was cleaned up by gel permeation chromatography(GPC)/solid-phase extraction (SPE). The GPC fraction was selectively collected, and loaded directly onto a graphitized carbon/PSA 2-layered column. After fractionation by 4% hydrated silica-gel column chromatography, each fraction was determined by dual-column GC-µECD. Recoveries of PCB, organochlorine pesticides and chlordanes were in the ranges of 84-109% (RSD ≤ 21.6%), 74-117% (RSD ≤ 14.6%) and 69-114% (RSD ≤ 12.9%), respectively. This method is superior to single chromatography for the determination of total PCB, and should be useful for monitoring of these pollutants in marine products.
