polybrominated diphenyl ethers (pbdes)

23.5-28 of 44 found

Fire retardants in furniture foam, computers, and televisions. Accumulate in human tissues. May harm brain development.

  • cumulative level found: 90.7 ppb (lipid weight) in breast milk
  • Moderate vs 20 tested in EWG/Commonweal studies (70th %ile)
9.51ppb (lipid weight) in breast milk1080


Total Polybrominated diphenyl ethers (PBDEs)

Brominated fire retardants currently used in plastics and fabric. The major use is in electronic devices; the minor use is as a backcoating on industrial fabrics. Are directly toxic to mammals and breakdown to more dangerous forms in the environment.

A fire retardant used in TVs, monitors and electronics. Growing evidence that chemical breaks down in the environment to more persistent and toxic forms.

  • level found: 0.17 ppb (lipid weight) in breast milk
  • Moderate vs 20 tested in EWG/Commonweal studies (65th %ile)
0ppb (lipid weight) in breast milk1.23


Brominated fire retardants used in polyurethan foam and plastics. These PBDEs are neurotoxic and persist in people and the environment. They were withdrawn from the market in the U.S. in 2005.
