摘要：

In this work, fly ash samples from Korean municipal solid waste incinerator (MSWIs) were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs) and heavy metals. From the comparison of PCDD/Fs homologue patterns with fly ash and flue gas, it was shown that fly ash has a catalytic potential for PCDD/Fs generation in actual combustion. Also, from the relationship between total PCDD/Fs and MSWI operating temperature, the temperature manifested itself as the most important factor in generating PCDD/Fs. Small amounts of PCBs also were found in fly ash and showed a positive correlation with PCDD/Fs. Although large amounts of heavy metals were detected, they do not have a noticeable relationship with PCDD/Fs levels in fly ash. From leaching tests, trace amounts of PCDD/Fs and heavy metals were detected in the leachate. (C) 1999 Elsevier Science Ltd. All rights reserved.
