Characterization of 'hidden' dioxins from informal e-waste processing

The composition of mixed brominated/chlorinated dibenzofurans (PXDFs) and diphenyl ethers in soils from an e-waste site in Ghana suggests a formation of PXDFs through condensation of the flame retardant PBDEs and subsequent bromine-to-chlorine exchange. PXDFs were substantial contributors of toxic equivalents among dioxins from e-waste burning.
