Congeners with equal numbers of bromine atoms are called PBDE homologs, which there are three types of: decabromodiphenyl ether (decaBDE), octabromodiphenyl ether (octaBDE), and pentabromodiphenyl ether (pentaBDE). OctaBDE and pentaBDE production halted at the end of 2004 in the U.S. after their manufacturer voluntarily phased out these chemicals.

Abstract. Organophosphate flame retardants (OPFRs) are used as replacements for the commercial PentaBDE mixture that was phased out in 2004. OPFRs are ubiquitous in the environment and detected at high concentrations in residential dust, suggesting widespread human exposure.

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.

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.

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.

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. 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

PentaBDE concentrations were above the guidelines for at least 1 sample in each drainage region. Figure 1. PBDE subgroup concentrations in fish relative to Posts about PentaBDE written by O Ecotextiles (and Two Sisters Ecotextiles) OctaBDE and pentaBDE were used in much smaller quantities than decaBDE.

endosulfan och pentaBDE är det vik- PentaBDE transfers from mothers to embryos and lactating infants. PentaBDE is "stored mainly in body fat" and may stay in the body for years. A 2007 study found that PBDE 47 (a tetraBDE) and PBDE 99 (a pentaBDE) had biomagnification factors in terrestrial carnivores and humans of 98, higher than any other industrial chemicals studied. While manufacture, import and use of C-PentaBDE commercial mixtures are prohibited, some articles containing this commercial mixture could still be in use in Canada and some may be recycled.

är t.ex. kvicksilver, oktylfenol, pentaBDE, och endosulfan. Kvicksilver är ett väl-känt och viktigt ämne men mer aktuellt i övervakningssammanhang som metyl-kvicksilver i biota. Oktylfenol är en möjlig ersättare till nonylfenol och kan av detta skäl därför vara intressant att följa. För bl.a. endosulfan och pentaBDE är det vik-

The octaBDE commercial mixture was primarily used in Commercial pentaBDE is a technical mixture of different PBDE congeners, with BDE-47 (2,2',4,4'- tetrabromodiphenyl ether) and BDE-99 (2,2',4,4',5-pentabromodiphenyl ether) as the most abundant. The term pentaBDE alone refers to isomers of pentabromodiphenyl ether (PBDE congener numbers 82-127). Only congeners with more than 1% listed. 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 concentration. The toxic effect of PentaBDE 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. Once it is released from products, it can be present on floors, furniture and other surfaces, and in air and dust.
