Common Sources of PBDE Exposure

Polybrominated diphenyl ethers (PBDEs) are chemicals used as flame retardants. (For a one-page description of PDBEs and related issues, read the PBDE BCERF Brief as a web page or in pdf format.) Some PBDEs have been identified as endocrine disruptors. They have been widely detected in people, wildlife, and the environment.

PBDEs are named for their chemical structure. Three types of PBDEs are used commercially.

Penta PBDE (includes 5 bromine atoms)
Octa PBDE (includes 8 bromine atoms)
Deca PBDE (includes 10 bromine atoms)

PBDEs are regulated differently according to the mixture (number of bromines). Deca PBDE is the least regulated mixture.

Penta PBDE Uses

Upholstery foams (polyethylene) in furniture, mattresses, auto seats, and office chairs.
Solid foams used in electrical appliances.

Octa PBDE Uses

ABS hard plastic in computer monitors, TV housings, and circuit boards.

Deca PBDE Uses

High impact plastic (polystyrene) housing for computers, TVs, and electrical appliances.
Textile coatings and backings for upholstery and drapes.
Polyethylene in wires, cables, and pipes.
