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). 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 In an investigation carried out by the WWF, "the brominated flame retardant chemical (PBDE 153), which is a component of the penta- and octa- brominated diphenyl ether flame retardant products" was found in all blood samples of 14 ministers of health and environment of 13 European Union countries. Se hela listan på ki.se Polybrominated diphenylethers (PBDE) belong to the group brominated flame retardants.

Each of these commercial products is a mixture composed of several PBDE congeners. 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. What are PBDEs? PBDEs are brominated hydrocarbons in which 2-10 bromine atoms are attached to the molecular structure (ATSDR 2015). PBDEs are used as flame retardants in a wide variety of products, including plastics, furniture, upholstery, electrical equipment, electronic devices, textiles and other household products (ATSDR 2015; EPA Particulate-phase pentabromodiphenyl ether will be removed from the atmosphere by wet or dry deposition.
Previous studies have found that the substances can leach into household dust and build up in the body where they may interfere with the thyroid, an organ that secretes brain-developing hormones. What is the issue? Polybrominated diphenyl ethers (PBDEs) are a group of brominated flame retardants that are found in a range of widely used consumer products including electronics and electrical equipment (e.g., television sets, computers, printers, fax machines, and cabling); transportation materials (e.g., plastics and upholstery in cars); and textiles (e.g., carpets and upholstery).
