Polybrominated diphenyl ethers (PBDE), which belong to a class of brominated hydrocarbon and are sometimes likened to brominated flame retardant (BFR) chemicals, have been widely utilized in the United States since the 1970s. Polybrominated diphenyl ethers (PBDEs) are used in large quantities as flame-retardant additives in a number of commercial products. Biomonitoring data show that, in recent years, PBDE concentrations have increased rapidly in the bodies of wildlife and humans. 2009 PBDE Flame Retardant Legislation On December 17, 2009, the principal manufacturers of decaBDE, Albemarle Corporation and Chemtura Corporation, and the principal importer, ICL Industrial Products, Inc., announced their commitment to a three-year phase-out of decaBDE.

Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles. PBDE används som additivt flamskyddsmedel. Dess användning är numera starkt reglerat inom EU. Exempel på varor som kan innehålla PBDE är plast- och gummimaterial i elektrisk och elektronisk utrustning, byggnadsmaterial, textilier och möbelstoppning.

Each of these commercial products is a mixture composed of several PBDE congeners. There are three types of commercial PBDE mixtures, including pentabromodiphenyl ether (pentaBDE), octabromodiphenyl ether (octaBDE) and decabromodiphenyl ether (decaBDE). DecaBDE is the most widely used PBDE globally (ATSDR 2015; EPA 2009).

There are three types of commercial PBDE mixtures, including pentabromodiphenyl ether (pentaBDE), octabromodiphenyl ether (octaBDE) and decabromodiphenyl ether (decaBDE). DecaBDE is the most widely used PBDE globally (ATSDR 2015; EPA 2009). The production of octaBDE and pentaBDE in the United States ceased

PBDEs are found in a variety of consumer products, from TVs and pbde Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in numerous polymer-based commercial and household products, such as textiles, furniture, and electronics, to increase their flame ignition resistance and to meet increasingly strict fire safety standards (Shaw and Kannan, 2009). Polybrominated diphenyl ethers (PBDEs) include the commercial versions of pentabromodiphenyl ether (c-pentaBDE), octabromodiphenyl ether (c-octaBDE), and decabromodiphenyl ether (c-decaBDE). Each of these commercial products is a mixture composed of several PBDE congeners. PBDEs are used as flame retardants in a number of applications, including Pentabromodiphenyl ether is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers.

Polybrominated diphenyl ethers (PBDEs) have been widely used to flame-retard products common in homes and the workplace, and subsequently, they have become widely dispersed in the environment.

PBDE flame retardants were commonly added to furniture, infant products, and electronics for many years. They have spread through the environment and break down slowly. U.S. production of some widely used PBDEs ended as of 2006, and the last major PBDE mixture is due to be phased out by the end of 2013.

Polybrominated diphenyl ethers (PBDEs) are a group of congeners, mainly used as flame retardants in a variety of materials including plastics, textiles, electronic products, building materials, furnishings and vehicles ( Figure 1 ). PBDEs may enter the environment through emissions from manufacturing processes, evaporation from products that
