what are brominated diphenyl ethers?
606248
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. ... PBDEs are classified according to the average number of bromine atoms in the molecule.

They include PCBs, dioxins, furans, hexachlorobenzene, benzo(a)pyrene (one of many polyaromatic hydrocarbons or PAHs), lead and mercury compounds and pesticides (toxaphene, mirex, aldrin/dieldrin, DDT). 3 Great Lakes Water Quality Agreement Work Group Report on Chemicals of Emerging Concern, August 2009.

PCBs (polychlorinated biphenyls) are chemical substances that have been commercially produced and sold as pure oil or in equivalent form from around 1929. They are extremely stable compounds with excellent electrical insulation and heat transfer properties.

Some PBDEs are lipophilic and bioaccumulative. PBDEs have been found in people all over the world. Some brominated flame retardants were identified as persistent, bioaccumulative, and toxic to both humans and the environment and were suspected of causing neurobehavioral effects and endocrine disruption.

Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include fluorine (F), chlorine (Cl), bromine (Br) and astatine (At).

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.

Ozone-depleting substances (ODS) are halogen gases containing chlorine and/or bromine which have the potential to break down ozone in the stratosphere. There are a significant number of ODS, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), methyl chloride and bromide, and halons.

The halogens are nonmetals that are located in group 17 on the periodic table, and the alkali metals are found in group 1. Halogens include fluorine, chlorine, bromine, iodine and astatine. Alkali metals include lithium, sodium, potassium, rubidium, cesium and francium.
