Environmental chemistry
PentaBDE is released by different processes into the environment, such as emissions from manufacture of pentaBDE-containing products and from the products themselves.Elevated concentrations can be found in air, water, soil, food, sediment, sludge, and dust.
Exposures and health effects
PentaBDE may enter the body by ingestion or inhalation.It is "stored mainly in body fat" and may stay in the body for years.[2] 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.[8] In an investigation carried out by the WWF, "the brominated flame retardant chemical (PBDE 153), which is a component of the penta- and octa- brominated diphenyl ether flame retardant products" was found in all blood samples of 14 ministers of health and environment of 13 European Union countries.
The chemical has no proven health effects in humans; however, based on animal experiments, pentaBDE may have effects on "the liver, thyroid, and neurobehavioral development."

Reported in EPA TSCA Inventory.

Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of Br⁻.
