Brominated　flame　retardants　(BFRs)　are　of　great　concern　due　to　their　wide　use　and　adverse　effects　to　environment　and　human.　The　existence　for　polybrominated　diphenyl　ethers　(PBDEs),　hexabromocyclododecanes　(HBCDs),　and　tetrabromobisphenol　A(TBBPA),　three　major　kinds　of　BFRs　found　in　environment　and　ecosystems　and　in　human　body　are　reviewed　briefly.　The　degradation　and　biotransformation　of　them　in　environmental　medium　(wastewater,　sludge　and　sediment),　organism　(microorganism　and　animals)　and　human　body　are　focused.　The　degradation　and　biotransformation　of　them　under　light　and　heat　are　of　great　concern　also.　The　degradation　pathway　and　metabolites　of　BFRs　are　introduced　in　detail.　In　addition,　the　future　research　and　prospects　are　also　discussed.
