Abstract
POPs including PCDDs, PCDFs and Co-PCBs are emitted to environment as unintentional by-products formed by various industrial activities according to development of technology. POPs have high toxicity, and they persist for long periods of time in the environment and can bio-accumulate from one species to the next through food chain. In many countries including Korea, there are enough researches about emission factors (EFs) and activity factors (AFs) on point sources. However, there is no sufficient data for establishment of EFs and AFs about non-point sources such as small combustion facilities, accidental fires, and uncontrolled conbustions. For non-point sources like these, EFs of these compounds are difficult to estimate because variable factors such as sampling method, composition, quality of incineration and combustion conditions make it hard to determine. In this study, a flux chamber was set to simulate an open-burning of waste wood(for construction/demolition) and domestic waste by incineration. And using the results, PCDD/DFs and Co-PCBs isomer patterns of open-burning would be compared with those of three MSWIs, and the effective emission factors should be suggested. From the results of simulation test, for waste wood, average value of PCDD/DFs and Co-PCBs was 0.215 ng WHO-TEQ/Nm3 and 0.026 ng WHO-TEQ/Nm3 respectively. Also, for domestic waste, average value of PCDD/DFs was 0.091 ng WHO-TEQ/Nm3 and that of Co-PCBs was 0.004 ng WHO-TEQ/Nm3. In addition, EFs for PCDD/DFs + Co-PCBs were estimated to 10.90 ng WHO-TEQ/kg and 7.66 ng WHO-TEQ/kg, respectively.
