Specific Substances: 2,2',4,4',5,5'-Hexabromodiphenyl ether (PBDE 153), Octabromodiphenyl ether, 2,2',4,4',5-Pentabromodiphenyl Ether, Pentabromodiphenyl Ether Mixture [DE-71 (Technical Grade)], 2,2',4,4'-Tetrabromodiphenyl Ether
Nomination Date: 07/27/1998
Nominator: Private Individual
Rationale: Polybrominated diphenyl ethers were nominated based on their bioaccumulative properties, the ongoing production of PBDEs, and the possibility for widespread human exposure through the food chain. There is a lack of subchronic and chronic toxicity information and a suspicion of neuro-developmental toxicity. Studies in rodents have shown hyperplasia of the thyroid and a decrease in circulating thyroid hormone levels after exposure to technical mixtures of PBDEs.
