Molecular Structure of PBDEs. Polybrominated diphenyl ethers (PBDEs) and deca-brominated diphenyl 8 Feb 2016 PBDEs is an abbreviation for polybrominated diphenyl ethers, which are man- made chemicals that are widely used as flame retardants in a PBDEs, or polybrominated diphenyl ethers, are a class of fire retardant chemicals. As part of NOAA's Mussel Watch Program, PBDEs are one of 150 different contaminants that are continually monitored by periodically sampling bivalves and sediment at 300 coastal sites around the nation. Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) belong to a class of chemicals that are added to certain manufactured products in order to reduce the chances that the products will catch on fire. 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. Polybrominated diphenyl ethers (PBDEs) include the commercial versions of pentabromodiphenyl ether (c-pentaBDE), octabromodiphenyl ether (c-octaBDE), and decabromodiphenyl ether (c-decaBDE).

CAS Number: 446255-56-7.

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.

CAS Number: 446255-56-7. … PBDEs and therefore is defined for edible parts of fish. The value is a sum of PBDE congeners 28, 47, 99, 100, 153 and 154, mainly representing penta- and octa- but not decaBDE.

PBDEs, or polybrominated diphenyl ethers, are industrial toxic flame retardant chemicals used in consumer electronics, furniture, and mattresses. PBDEs are no longer produced in the U.S. but are still present in many items in our homes and elsewhere. How am I exposed? Polybrominated diphenyl ethers (PBDEs) are a class of synthetic chemicals first produced commercially in the 1970s. They are added to products such as foam padding, textiles, or plastics to retard combustion. 2,2′,4,4′,5,5′-hexabromobiphenyl (BB-153) is a brominated biphenyl that was used as a flame retardant in the U.S. until the 1970s.

Synonym: 2,3,3′,4,4′,5,5′,6-OctaBDE, 2,3,3′,4,4′,5,5′,6-Octabromodiphenyl ether solution, PBDE 205. Empirical Formula (Hill Notation): C12H2Br8O. Molecular Weight: 801.38. CAS Number: 446255-56-7.

Just like PCBs, there are 209 PBDE congeners (Fig. 1), and they are named in … PBDE 28. Molecular Formula C 12 H 7 Br 3 O; Average mass 406.895 Da; Monoisotopic mass 403.804688 Da; ChemSpider ID 10239063 For example, the PBDE congener, 2,2',4,4'-tetraBDE may be referred to as BDE 47 in this document. The identities of several PBDE congeners are shown in Table 4-1 (WHO 1994a, 1994b). In the United States, Albemarle Corporation and Great Lakes Chemical Corporation previously marketed A decrease of PBDE concentrations in Swedish milk has also been indicated by Lind and co-workers 2003 (10). In Norway, PBDE concentrations in human milk increased from 1986 to 2001 (11), within a similar concentration range as reported in Sweden and in Japan (8-10,12). These temporal trend studies all indicate decreasing PBDE concentrations, 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 ).
