Notes:
Some possible intermediates or by-products in the synthesis of polychlorodibenzo-p-dioxins and dibenzofurans in municipal waste incinerators are presented. In stack gas samples from two different incinerators, the following compounds were tentatively identified: polychloromonobenzofurans, polychloromonobenzodioxins, monobromopolychlorobenzenes and polychlorothiophenes. The occurrence of complete series of homologues and **isomers with an increasing degree of chlorination suggests an analogus formation mechanism with common precursors. The presence of these compounds in the vapour phase, the non-regiospecific character of these reactions and the high reaction temperature and speed confirm a radical mechanism of formation.
