Abstract
The efficiency of a large wet-only precipitation collector for polychlorinated biphenyl (PCB) analysis was investigated using generator column-produced solutions. Total recoveries were quantitative for two experiments utilizing mixed Aroclor generator columns for the PCB source, with input-weighted average congener recoveries of 104 and 99%. Small losses were observed on the filter and collection reservoirs (> 3%), and no breakthrough to the second extraction cartridge was observed. Loss to the collector surface was 11 and 2%, and in the first case most likely reflects contamination rather than actual retention during the experiment. Individual congener recoveries generally rather than actual chlorination, a relationship that may be due mostly to analytical uncertainties for more highly chlorinated congeners.
