This study determinated the polychlorinated dibenzo-ρ-dioxins and dibenzofurans (PCDDs and DFs) in fly ash and bottom ash of industrial waste incinerators. Experimental results showed that average PCDDs and DFs concentrations in fly ash were 4.5063 and 13.004 ng-TEQ/g, and in bottom ash were 0.2367 and 0.0993 ng-TEQ/g, respectively. Predominant congener in TEQ of PCDDs/DFs from fly ash were 1,2,3,4,6,7,8-HpCDD, OCDD, 2,3,4,6,7,8-HxCDF, 2,3,4,7,8-PeCDF and in bottom ash were 1,2,3,7,8-PeCDD and 2,3,4,7,8-PeCDF.
