DOI: http://dx.doi.org/10.1065/ehs2001.06.008.1 -- Different mechanisms downstream from high temperature processes lead to the formation of polychlorinated di-benzo(p)-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Independent from any concentrations, these mechanisms cause comparable PCDD/F patterns, the percentage proportion of single congeners or homologue groups relating to the total 17 2378-Cl-substituted congeners resp. to the sum of the homologue groups tetra- to octaCDD/F. The characteristics of these socalled combustion profiles can help to interpret corresponding data from burning and melting facilities, such as municipal waste incinerators, coal power plants, sintering plants, metal finishing facilities, cement kilns, crematoria, hazardous waste incinerators and landfill gas burners. |
