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based on a no-observed-adverse-effect level (NOAEL) of 1.8 mg/kg-day for PentaBDE and octaBDE mixtures were voluntarily withdrawn from the U.S. marketplace by their manufacturers at the end of 2004 and decaBDE was not to be manufactured or imported into the United States after December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. 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.

Commercial octaBDE (also known as "Octabrom") is a technical mixture of different PBDE congeners having an average of 7.2 to 7.7 bromine atoms per molecule of diphenyl ether. The predominant congeners in commercial octaBDE are those of heptabromodiphenyl ether and octaBDE. 2011-11-01 2013-02-01 PentaBDE är namnet på en kommersiell produkt som använts för flamskydd.
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. PentaBDE is used mainly in rigid and flexible polyurethane foams and polyurethane elastomers. Most of this polyurethane is used in turn in upholstery and furnishing. Global market demand for pentaBDE has more than doubled in the last decade to the present 8,500 metric tn per year.

Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants. Technical mixtures PentaBDE and OctaBDE were phased out in 2004 through voluntary and regulatory actions with DecaBDE remaining in limited use until 2013. Biomonitoring studies have shown widespread presence of PBDEs in the US a …
OctaBDE and pentaBDE production halted at the end of 2004 in the U.S. after their manufacturer voluntarily phased out these chemicals. In December 2009, the main importer of decaBDE in the U.S. announced a phaseout of their chemicals by 2013. PentaBDE, the use of TDCPP increased signiﬁcantly.
