산업폐기물 소각장의 비산재와 바닥재에서 PCDDs와 DFs를 측정한 결과, 비산재에서 PCDDs와DFs의 농도는 각각 4.5063과 13.004 ng-TEQ/g이었고 바닥재에서는 0.2367과 0.0993 ng-TEQ/g의 함유량을 보였다. 비산재 속에는 1,2,3,4,6,7,8- HpCDD, OCDD, 2,3,4,6,7,8-HxCDF, 2,3,4,7,8-PeCDF 동종체가 다량 함유되었고 바닥재에는 1,2,3,7,8-PeCDD와 2,3,4,7,8-PeCDF가 많았다.
Abstract
This study determinated the polychlorinated dibenzo-ρ-dioxins and dibenzofurans (PCDDs andDFs) in fly ash and bottom ash of industrial waste incinerators. Experimental results showed that averagePCDDs and DFs concentrations in fly ash were 4.5063 and 13.004 ng-TEQ/g, and in bottom ash were 0.2367and 0.0993 ng-TEQ/g, respectively. Predominant congener in TEQ of PCDDs/DFs from fly ash were1,2,3,4,6,7,8-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-PeCDDand 2,3,4,7,8-PeCDF.
