| Hexabromobiphenyl is a white, chalky solid persistent, organic pollutant that belongs to a wider group of polybrominated biphenyls (PBBs). The term “polybrominated biphenyls” or “polybromobiphenyls” refers to a group of brominated hydrocarbons formed by substituting hydrogen with bromine in biphenyl. The hexabromo congeners exist as 42 possible isomeric forms. | POPs Convention accessed on 06 October 2020 | Link |
| Polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), and brominated flame retardants (BFRs) belong to a group of chemicals known as organohalogens. Organohalogens are organic compounds that contain chlorine, bromine, or fluorine atoms and the molecules are named as chlorinated, brominated, or fluorinated hydrocarbons, respectively. These compounds share common characteristics such as persistence in the environment, bioaccumulation in living organisms, long-range transport beyond the geographical regions of their use, and long-term health effects in wildlife and humans. Even though some of these compounds (e.g. PCBs and PBBs) have been banned or severely restricted in use in developed countries for more than three decades, they are still found in every component of the global ecosystem and pose a threat to human health | Kodavanti and Loganathan., 2014.

| Polybrominated biphenyls (PBBs) are a class of halogenated biphenyls where 1–10 hydrogen atoms are replaced with bromine atoms. Although they are called PBBs, monobrominated structures (i.e., one bromine atom attached to biphenyl molecule) are included when describing PBBs. Bromine atoms can bind to the biphenyl molecule in 209 possible configurations resulting in 209 possible compounds called congeners; however, actual congeners found in PBB mixtures are much fewer. PBBs are usually white, off-white, or beige powders at room temperature. All congeners are very soluble in fat and organic solvents such as benzene and toluene and insoluble in water. PBBs are extremely stable, consequently persistent in the environment. At present PBBs have limited uses, for example in electric and electronic products sold in the EU; however, they had been widely used commercially as flame-retardant additives in synthetic fibers and molded plastics and as a fire retardant in lacquers and coatings and in automobile upholstery. | Saghir., 2018.
