Description
Composition of commercial Tetrabromodiphenyl ether: 7.6% polybrominated diphenyl ethers, 41-41.7% tetrabromodiphenyl ether, 44.4-45% pentabromodiphenyl ether and 6-7% hexabromodiphenyl ether." [HSDB]
Sources/Uses
Used as flame retardants, typically at 3 to 12% of the product; Workers may be exposed during the weighing and mixing of flame retardant resins and polymers; [NICNAS: Polybrominated Flame Retardants - 2001]
Comments
The primary health concerns of polybrominated flame retardants are their potential to act as carcinogens, endocrine disruptors, and neurodevelopmental toxicants; Polybrominated diphenyl ethers (PBDPEs) may have effects on the liver and possibly the thyroid; The majority of the absorbed tetrabromdiphenyl ether is stored in adipose tissue; Adverse effects may include lowering of the serum and total T4 thyroid hormone; [NICNAS: Polybrominated Flame Retardants - 2001] See "Phenyl ether."
