Repartition of PCDD and PCDF in the emissions of municipal solid waste incinerators between the particulate and volatile phases.
The present paper refers to the results of a research project on the polychlorinated dibenzyil-p-dioxin (PCDD) and polychlorinated dibenzofurans repartition in particulate and volatile phase in emissions from municipal solid waste incinerators. The distribution of such micropollutants between the different phases is analyzed in terms of absolute weights and in terms of 2, 3, 7, 8 TCDD Equivalents. This paper shows that more than half of the total content of PCDD/Fs emitted are adsorbed in the fly ash, with the remaining part in the volatile phase. Such repartition is inverted if the PCDD/Fs are expressed in terms of 2, 3, 7, 8 TCDD Equivalent.
