A 2002 study estimated that 80 percent of c-pentaBDE was used in foam for furniture and mattresses, while the remaining Pentad definition is - a group of five. History and Etymology for pentad. Greek pentad-, pentas, from pente 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.

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. In addition, a mixture of nonhalogenated organophosphate FRs that included triphenyl phosphate (TPP), tris(4-butylphenyl) phosphate (TBPP), and a mix of butylphenyl phosphate isomers were
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.
