Acronym, Definition. PBDE, Polybrominated Diphenyl Ether. PBDE, Pentabromodiphenyl Ether (flame retardant additive in plastics). PBDE, Post- Baccalaureate

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.

Med biomagnifiering menas att koncentrationen av en kemikalie är högre i djur som befinner sig högre upp i näringskedjan, det vill säga djur som har en högre trofinivå. Till skillnad från PCB Polybromerade difenyletrar (PBDE) är en samlingsbeteckning för ett antal av de mest använda bromerade flamskyddsmedlen med stor spridning i miljön. Ämnena är fettlösliga och lagras i fisk. Tillverkningen av varor och produkter med flamskyddsmedel är mycket stor. EFSA was asked by the European Commission to deliver a scientific opinion on polybrominated diphenyl ethers (PBDEs) in food. PBDEs are additive flame retardants which are applied in plastics, textiles, electronic castings and circuitry.

Polybrominated diphenylethers (PBDE) belong to the group brominated flame retardants. There are three commercial PBDE mixtures that have primarily been used: Penta-, Octa- and Deca-bromodiphenylether, where the nomenclature reflects the number of bromine atoms included in the main components in the mixture. Sum PBDE levels increased significantly in the serum of the exposed females from 218 +/- 43 to 23,400 +/- 2035 pg/mL.

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. Detailed compositional knowledge of these complex PBDE mixtures is crucial to a fuller understanding of their toxicological potencies and environmental fate due to selective congener biomagnification

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.

PBDEs is the shorthand for a class of chemicals called polybrominated diphenyl ethers. PBDEs are one of the most common kind of toxic flame retardant used in common household products and materials such as furniture, electronics, textiles, vehicles, and construction materials.

DecaBDE is the most widely used PBDE globally (ATSDR 2015; EPA 2009). The production of octaBDE and pentaBDE in the United States ceased PBDE is still under investigation, research has established that it is persistent, bioaccumulative, and toxic.

2013-03-28 2001-07-25 · Polybrominated diphenyl ether, PBDE, flame retardants are now a world-wide pollution problem reaching even remote areas. They have been found to bioaccumulate and there are concerns over the health effects of exposure to PBDEs, they also have potential endocrine disrupting properties. PBDE congeners (La Guardia et al., 2006). Congeners that occurred in historically important pentaBDE technical products by >5% weight investigated by LaGuardia et al. include congeners 47, 99, 100, 153; mainly the tetra BDE47 and penta BDE99) (La Guardia et al., 2006). The c-octa mixtures analysed consisted mainly of BDEs number 183 Polybrominated Diphenyl Ethers (PBDE): 1000 ppm (0.1%) Similar to PBBs - added to plastic enclosures to make them difficult to burn. Known human carcinogen that affects the endocrine system.
