The PentaBDE phase-out did not require the destruction of existing gym pads and other foam furniture. The managers of the gyms where the athletes in the study practiced reported that the foam cubes lining the gym pits were 10 to 20 years old, purchased when PentaBDE was still legally sold.

OctaBDE and pentaBDE were used in much smaller quantities than decaBDE. Polybrominated biphenyls (PBB) have also been used, but production was stopped

Information collected by the. National Industrial Chemicals Notification and Assessment Scheme ( 9 Jul 2008 i) prohibit the manufacture of PBDEs (tetraBDE, pentaBDE,. hexaBDE, heptaBDE , octaBDE, nonaBDE and decaBDE congeners.

Pentabde

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. Novel and High Volume Use Flame Retardants in US Couches Reﬂective of the 2005 PentaBDE Phase Out Heather M. Stapleton,*,† Smriti Sharma,† Gordon Getzinger,† P. Lee Ferguson,† Michelle Gabriel,§ Thomas F. Webster,‡ and Arlene Blum§ †Nicholas School of the Environment, Duke University, Durham, North Carolina, United States ‡Department of Environmental Health, Boston University Flame retardant chemicals such as HBCD (hexabromocyclododecane) and pentaBDE (pentabromodiphenyl ether) raise concerns for human health and the environment, including potential reproductive, developmental, and neurological effects and can be persistent, bioaccumulative, and toxic to aquatic organisms. 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.

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.

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. Once it is released from products, it can be present on floors, furniture and other surfaces, and in air and dust.

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 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. Translations in context of "PentaBDE" in English-Italian from Reverso Context: This amendment goes beyond the present proposal to restrict the marketing and use of pentaBDE. PentaBDE was the second most frequently detected FR (n = 17) with an average concentration of 18.34 mg/g of foam and ranging from 6.54 to 43.17 mg/g of foam. 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.
