CHARACTERISTICS OF POLYBROMINATED DIPHENYL ETHERS (PBDES) AND POLYBROMINATED DIBENZO-P-DIOXINS AND DIBENZOFURANS (PBDD/FS) IN THE BOTTOM AND FLY ASHES OF MUNICIPAL SOLID WASTE INCINERATORS
As yet, very little is known about the characteristics of of polybrominated diphenyl ethers (PBDEs) and polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) in the ashes of municipal solid waste incinerators (MSWIs). In this study, the ashes in different units of two MSWIs were sampled to measure the PBDEs, PBDD/Fs and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). Bottom ashes (BA) exhibited much higher PBDD/F (8.11 – 52.2 pg TEQ/g) and PBDE contents (20.4 – 186 ng/g) than those of fly ashes (0.0932 – 2.02 pg TEQ/g, and 0.332 – 25.5 ng/g), revealing that PBDD/Fs and PBDEs in the feeding waste may not be completely destroyed. In addition, PBDE contents in BA were one to three orders higher than those found in contaminated site soils or reference soils. The reutilization of BA of MSWIs for beneficial purpose, however, might add PBDEs to the environmental loading, which should not be ignored while developing a PBDE inventory.
