Definition of Pentabromoethylbenzene (PBEB):
Pentabromoethylbenzene is a brominated flame retardant
This is the common definition for Pentabromoethylbenzene (PBEB), other definitions can be discussed in the article

| Formula |
| C8H5Br5 |
PBEB was produced in the US until 1990, with a US production in 1986 between 4 and 226 tonnes. PBEB was used in the 1970’s and 1980’s to make the thermoset polyresins found in circuit boards, textiles, adhesives, wires, cables, and polyurethanes, from which they continue to leak in the environment.
PBEB is likely to be an extreme persistent chemical with a very high potential for bioaccumulation. There is however no data available on it's toxicity. [1] [2]
