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. C-PentaBDE has been used as a flame retardant additive in flexible polyurethane foam for furniture and upholstery and in electronic equipment. The main source in North America and Western Europe has been the C-PentaBDE incorporated in polyurethane foam, used in domestic and public furniture. C-PentaBDE has been produced in Israel, Japan, US and the EU, but production in these regions ceased in the beginning of this millenium.

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. Alternatives might not be available for use in military airplanes. Technical pentabrominated diphenyl ether (pentaBDE mix) is a mixture of polybrominated diphenyl ethers (PBDEs) which has been widely used as a flame retardant.

Define PentaBDE. means pentabromodiphenyl ether or any technical mixture in which a pentabromodiphenyl ether is a congener. An IRIS assessment of commercial pentaBDE (CASRN 32534-81-9) was previously entered on IRIS on 08/01/1990. 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based on a no-observed-adverse-effect level (NOAEL) of 1.8 mg/kg-day for PentaBDE and octaBDE mixtures were voluntarily withdrawn from the U.S. marketplace by their manufacturers at the end of 2004 and decaBDE was not to be manufactured or imported into the United States after December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.
