Description:
The paper discusses the formsation of endocrine disrupting compounds (EDCs) from precursors, such as phenol and chlorobenzens, under various combustion conditions. It gives results of an exploration of the effects of precursor and catalysys composition on homologue production and distribution to provde insight into the mechanisms of this EDC formation. (NOTE: EDCs are believed to pose serious health and ecological threats. An understanding of the sources and formation of these chemicals must be attained in order to control their release into the environment. Combustion devices are a source of potentially significant EDC releases. There is already a general acceptance of the theory of formation of the EDCs polychlorinated dibenzo-p-dioxins and deibenzofurans (PCDD/Fs) in incinerators; however, these two groups of compounds make up only a portion of EDC emissions. Other EDCs, including polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes, are believed to follow similar formation mechanisms and trends).
