PentaBDE är namnet på en kommersiell produkt som använts för flamskydd. Den består av flera olika varianter av bromerade ämnen (kongener). Mätvärdena visar den sammanlagda halten av de två kongener som förekommer i högst halter i blandningen (BDE47 och BDE 99). PentaBDE finns på vattendirektivets lista över prioriterade ämnen.

(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.

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. Meaning of pentabde.

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).

Until recently, pentabromodiphenyl ether (PentaBDE) was most commonly used as a flame retardant.

Flame retardant manufacturers in the U.S. voluntarily stopped producing the PentaBDE (used in furniture foam) and OctaBDE (used in electronic products) varieties of PBDEs in 2004 and have begun producing alternative flame retardants; however, DecaBDE continues to be produced and used in the U.S., primarily in television casings.

PentaBDE means pentabromodiphenyl ether or any technical mixture in which a pentabromodiphenyl ether is a congener. means pentabromodiphenyl ether or any technical mixture in which a pentabromodiphenyl ether is a congener. 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 PentaBDE and octaBDE mixtures were voluntarily withdrawn from the U.S. marketplace by their manufacturers at the end of 2004 and decaBDE was not to be manufactured or imported into the United States after December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). Pentabromodiphenyl ether (PentaBDE) was administered intragastrically to female rats, in a single dose (25, 200 or 2000 mg/kg b.w.).

The term pentaBDE alone refers to isomers of pentabromodiphenyl ether (PBDE congener numbers 82-127). 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 higher liver glutathione reduced ( GSH ) concentration.

PentaBDE is a commercial flame retardant mixture containing brominated chemicals called PBDEs (polybrominated diphenyl ethers). PentaBDE has been used for decades in residential furniture, but due to concerns over their persistence, ability to accumulate in humans, as well as their potential toxicity, the US began a phase-out of pentaBDE in 2005.

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.
