It 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. 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 applied OECD407 protocol was enhanced for endocrine and immune parameters, and to enable benchmark dose analysis. Visiting addresses: Geovetenskapens Hus, Svante Arrhenius väg 8, Stockholm.

Pentabde

History and Etymology for pentad. Greek pentad-, pentas, from pente The commercial pentaBDE consisted mainly of pentaBDE (58%), tetraBDE (25%), and hexaBDE (13%) (Carlson, 1980a). An RfD of 0.002 mg/kg-day was derived, based on a no-observed-adverse-effect level (NOAEL) of 1.8 mg/kg-day for induction of hepatic enzymes in a … We've got 0 rhyming words for c-pentabde » What rhymes with c-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.

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. TetraBDE and pentaBDE Alternatives are available and used to replace these substances in many countries, although they might also have adverse effects on human health and the environment.

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. Polybrominated biphenyls (PBB) have also been used, but production was stopped Organophosphate flame retardants (OPFRs) are used as replacements for the commercial PentaBDE mixture that was phased out in 2004.

Once it is released from products, it can be present on floors, furniture and other surfaces, and in air and dust. PentaBDE är klassificerad som miljöfarligt och hälsoskadligt.

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. 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 may enter the body by ingestion or inhalation. It is "stored mainly in body fat" and may stay in the body for years.
