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. PentaBDE is used mainly in rigid and flexible polyurethane foams and polyurethane elastomers.

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.

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. 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. A vehicle control group and 7 dose groups were included, which received 0.
