Study on integrated management of PCB containing waste and PCB contaminated waste: proposal of new congeners for quantification

摘要

In the present study, new congeners were selected for the efficient management of PCB containing waste and PCB contaminated waste, and the applicability of these new indicators was confirmed. As a result, 8 indicator congeners and 4 index peaks which were named "Proposed new method 1" and "Proposed new method 2" were selected. For the assessment of a novel quantitative method, comparative tests using conventional methods were conducted, and the factors for total PCB were calculated for each method. Results from these tests showed that the average values for the factors of CEN/TC19/WG22, DIN 51527, and the test method by the disposal regulation for ocean dumping in Korea were 1.86, 3.47, and 2.52, respectively, while those for the proposed new method 1 and proposed new method 2 were 2.98 and 5.56, respectively. For PCB contaminated waste, the factor was found to be 1.99, 3.42, and 3.02 using the conventional methods, 2.67 using the proposed new method 1, and 5.57 using the proposed new method 2. It is expected that, in accordance with the results of the present study, the management of PCB waste can be integrated, regardless of the type of waste involved.
