Abstract : A method and apparatus is disclosed for producing an extract for testing substances including soil and water for contamination by polychlorinated biphenyl (PCB), using commercially available test units which are normally limited to testing transformer oils. The method consists of: taking a sample of a substance suspected of PCB contamination; mixing it with an equal mass of hexane solvent in a sample bottle; and shaking the sample bottle by hand for 30 seconds to yield a hexane extract. The hexane extract is then analyzed using the commercially available field test kit. Finally, the results yielded by the commercially available field test kit are multiplied by a scaling factor to yield an estimate of the actual amount of PCB contamination in the sample.
