The study evaluated the biotransformation of TBBPA in anaerobic digester sludge, soils, and freshwater sediments. The results of this study were consistent with previously published studies where TBBPA biotransformed in anaerobic environments (digester sludge and sediments) by debromination and slowly mineralized in the test environments (anaerobic digester sludge, soils, and freshwater sediments).1Source: McAvoy, Drew C., Charles A.
