Flame Retardants

Decabromodiphenyl ether (BDE-209)
1163-19-5

Where is it Commonly Found?

Decabromodiphenyl ether (DecaBDE) is primarily used in electronic housings and textile back coating (La Guardia et al. 2006), as well as molded plastic parts made of ABS, high-impact polystyrene (HIPS), polyethylene, and polypropylene, and as a coating on PET film (Illinois EPA 2007). It is also used as a fire retardant additive in thermoplastic resins, polyethylene, polystyrene, adhesives, polyester fibers and coatings for textiles, and paints. DecaBDE is used in combination with another flame retardant, antimony trioxide, for polystyrene products used in TV and computer monitor cabinets (Alaee et. al. 2003).

HEALTH EFFECT SUMMARY

The U.S. EPA has classified decaBDE as a possible human carcinogen (class C) due to significantly increased incidences of neoplastic liver nodules found in rats and increased incidences of combined hepatocellular adenomas or carcinomas in male mice (EPA 2008). Ingestion of dust appears to be the major exposure pathway of decaBDE. Toddlers have significant exposure from hand-to-mouth contact leading to dust ingestion, as well as their intake of breast milk containing decaBDE (Frederiksen et al. 2009).

One controversial issue surrounding decaBDE is the extent of debromination to more toxic and bioaccumulative, less-brominated congeners within the environment (Stapleton et al., 2006). Debromination leads to other BDE congeners similar to those found in banned penta- and octaBDE mixtures.

Additional Facts

Decabromodiphenyl ether was the second most commonly used brominated fire retardant as of 2001 (Morose 2006). Over 40% of worldwide production of decaBDE was used in North America (Illinois EPA 2007). However, US EPA has received commitments from the industry that all sales of decaBDE in the US will cease by December 31, 2013 (US EPA 2011).
