Where is it Commonly Found?
Ninety per cent of the usage of TBBPA is as a reactive flame retardant for epoxy resins in printed circuit boards. Additional uses include ABS plastic resins, HIPS and in certain adhesives and coatings (IPCS 1995; CEFIC 2007). Derivatives of TBBPA are also used as flame retardants; these include TBBPA-DBPE and TBBPA-OHEE.
TBBPA shows estrogenic activity in animals and inhibits neurotransmitter uptake affecting dopamine, GABA, and glutamate (OEHHA 2008). TBBPA exhibits thyroid hormone activity in vivo and in vitro (Van der Ven et al., 2008) and . The European Community Directive on Dangerous Substances deemed TBBPA “very toxic to aquatic organisms” and it “may cause long-term adverse effects in the aquatic environment”; however, the EC found no risk to human health from TBBPA based on existing risk-mitigation protocols (European Community 2008).
Exposure: TBBPA has been found in soils, sediments, fish, marine mammals and predatory bird eggs (OEHHA 2008). TBBPA is partly degraded in soil, in river sediment and in water under both aerobic and anaerobic conditions (OEHHA 2008).
How is it Categorized?
TBBPA is a derivative of Bisphenol A (BPA). With a 59% share of the global market of brominated fire retardants in 2001, Tetrabromo-bisphenol-A (TBBPA) is the highest volume halogenated flame retardant worldwide (Morose 2006).
