A 28-day subacute oral toxicity study was performed in Wistar rats with a purified preparation of the commercial pentabromodiphenyl ether (pentaBDE), DE-71. The applied OECD407 protocol was enhanced for endocrine and immune parameters, and to enable benchmark dose analysis. A vehicle control group and 7 dose groups were included, which received 0.

Examples of PBDE congenes – BDE-47, BDE-99 and BDE-183. technique. PentaBDE, OctaBDE and DecaBDE technical formulations are characterized under the method and results for a typical high-impact polystyrene sample are also presented. Determination of Polybrominated Diphenyl Ethers in Polymeric Materials Using the 6890 GC/5973N inert MSD with Electron Impact Ionization Application Introduction ether (pentaBDE) and octabromo-diphenyl ether (octaBDE) have been assessed under Council Regulation (EEC) No 793/93 of 23 March 1993 on the evaluation and control of the risks of existing substances(4).

Pentabromodiphenyl ether (PentaBDE) was administered intragastrically to female rats, in a single dose (25, 200 or 2000 mg/kg b.w.). PentaBDE administered to rats disturbed redox homeostasis, which was manifested by lower total antioxidant status (TAS) in serum and by … Synonym: 1,2,4-Tribromo-5- (2,4-dibromophenoxy)benzene, 2,2′,4,4′,5-PentaBDE, 2,2′,4,4′,5-Pentabromodiphenyl ether, BDE 99, PBDE 99. Empirical Formula (Hill Notation): C12H5Br5O. Molecular … Pentabromodiphenyl ether (pentaBDE, penta-BDE, PeBDE, penta, pentabromodiphenyl oxide, PBDPO) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). Additional recommended knowledge. PentaBDE mixture can be gradually released from older items made with polyurethane foam and plastics, into indoor environments such as houses, schools, day care centers, and offices.

All but one of these foam samples containing PentaBDE was purchased prior to 2005, the year of its phase-out in the U.S. The one remaining sample was purchased in 2005.

Composition, uses, and production. Commercial octaBDE (also known as "Octabrom") is a technical mixture of different PBDE congeners having an average of 7.2 to 7.7 bromine atoms per molecule of diphenyl ether. The predominant congeners in commercial octaBDE are those of heptabromodiphenyl ether and octaBDE.

PentaBDE was principally used in foam for cushioning in upholstery. PentaBDE and octaBDE mixtures were voluntarily withdrawn from the U.S. marketplace by their manufacturers at the end of 2004 and decaBDE was not to be manufactured or imported into the United States after December 31, 2013.

The term pentaBDE alone refers to isomers of pentabromodiphenyl ether (PBDE congener numbers 82-127).

2011-11-01 · Elevated PentaBDE body burdens in humans are associated with adverse effects on circulating hormone levels, fecundability, impaired neurodevelopment, and an increased incidence of adverse birth outcomes, such as decreased weight and cryptorchidism (Chao et al., 2007, Main et al., 2007, Turyk et al., 2008, Meeker et al., 2009, Harley et al Translations of the phrase CON PENTABDE from spanish to english and examples of the use of "CON PENTABDE" in a sentence with their translations: contienen componentes sólidos o espumas con pentabde , se almacenan en exteriores Se hela listan på pops.int Translations of the word PENTABDE from english to finnish and examples of the use of "PENTABDE" in a sentence with their translations: the marketing and use of pentabde .

The commercial polybrominated diphenyl ether (PBDE) mixture known as PentaBDE was once the primary flame retardant (FR) used in the United States to meet California’s Technical Bulletin 117 (TB117)—a mandated flammability standard for polyurethane foam within upholstered furniture and baby products classified as juvenile furniture (Stapleton et al., 2011; State of California, 2000). A 28-day subacute oral toxicity study was performed in Wistar rats with a purified preparation of the commercial pentabromodiphenyl ether (pentaBDE), DE-71.

The toxicity of this compound has been well documented in the literature, especially with regard to the endocrine system, induction of liver microsomal enzymes, and disturbance of redox (5) The presence of pentaBDE or octaBDE in concentrations higher than 0,1 % can be identified using standard analytical techniques such as GC-MS (gas chromatography-mass spectrometry). (6) The risk assessment on decaBDE was concluded in August 2002 and has revealed a number of uncertainties concerning possible effects on the environment of this substance. Until recently, pentabromodiphenyl ether (PentaBDE) was most commonly used as a flame retardant. On account of the hazardous effect of PentaBDE on the environment, its use was discontinued some years ago.

C-PentaBDE has been produced in Israel, Japan, US and the EU, but production in these regions ceased in the beginning of this millenium. There are indicative reports of an expanding production of brominated flame retardants in China. No official information is available for production of c-PentaBDE in China, which is also the case for Israel and Definition of pentabde in the Definitions.net dictionary.
