%X Trace PCBs in the effluent from a pulp bleaching process with liquid chlorine or deactivated chlorinated lime were quantitatively determined with a method in which the samples were enriched by using a resin GDX-501, then extracted, washed with a concentrated sulfuric acid, and cleaned up over a deactivated alumina-silver nitrate-siliCa gel column before determination using a gas chromatography with a capillary and an electron capture detector. The PCBs in the effluent were found to be at a level in the range of 10-12-10-9 and to consist of dominant PCBs substituted with less (2 or 3) chlorines.
