This study focused on transformation of the flame retardant tetrabromobisphenol A (TBBPA) and ether derivatives thereof during incubation under methanogenic conditions using landfill waste as inoculum. Bisphenol A dimethyl ether was also investigated in that context. Glass wool was placed in the incubation flasks to increase the surface area for adsorption of target compounds and thereby maximize exposure to the microbial population. A uniform analytical protocol for extraction of the silica surface and the aqueous phase was developed to suit all the targets. Overall recoveries were lowest for the dimethylated ethers and highest for TBBPA-dihydroxyethylether. TBBPA decreased to below detection limit within 35 days, but neither BPA nor the methyl ether of TBBPA was confirmed as a transformation product. The dimethylated ethers of BPA and TBBPA disappeared within 14 and 51 days, respectively, and BPA, but not TBBPA, proved to be a transformation product. No losses were observed for the most hydrophobic target TBBPA-dibromopropyl ether during the time frame of the transformation study (i.e., 51 days).
