초록

Emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurnas (PCDFs) in stack gas were analyzed from 21 municipal solid waste incinerators (MSWs) using high resolution gas chromatography equipment with a high resolution mass spectrometer (HRGC/HRMS) in 2015. The concentration of PCDDs/DFs was in the range 0.09 ~ 354.54 pg-TEQ/Sm3 based on the International Toxicity Equivalency Factor (I-TEF) and all MSWs complied with emission standards. The congener distribution of PCDDs/DFs was categorized into one group and two outliers via principal component analysis (PCA). Among the 17 PCDDs/DFs, 1,2,3,4,6,7,8-HpCDD showed the highest mass fraction (20.8%) and 2,3,4,7,8-PeCDF showed the largest TEQ contribution (42.9%).
