| Abstract: | Laboratory bleaching experiments were performed to investigate PCDD/PCDF formation mechanisms. The results indicated that there were two (or more) mechanisms; direct chlorination of DBD/DBF and formation from precursors which are not extractable. In general, PCDDs/PCDFs are formed in the C stage but some minor isomers were found to be formed in the E stage. |
