polybrominated diphenyl ethers (pbdes)
8 of 20 found
Polybrominated diphenyl ethers (PBDEs)
Fire retardants in furniture foam, computers, and televisions. Accumulate in human tissues. May harm brain development.
- cumulative level found: 18.6 ng/g (lipid weight) in blood serum
[excludes PBDE-154/PBB-153] - Moderate vs 116 tested in EWG/Commonweal studies (43rd %ile)
- Moderate vs 2,337 tested in CDC biomonitoring [1] (26th %ile) (comparison based on congeners tested by CDC)
1.11 | ng/g (lipid weight) in blood serum | 314 |

Total Polybrominated diphenyl ethers (PBDEs)
- level found: 0.44 ng/g (lipid weight) in blood serum [s]
- Moderate vs 40 tested in EWG/Commonweal studies (63rd %ile)
0.11 | ng/g (lipid weight) in blood serum | 1.95 |

Decabrominated diphenyl ethers
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: 2.44 ng/g (lipid weight) in blood serum [s]
- High vs 116 tested in EWG/Commonweal studies (86th %ile)
ng/g (lipid weight) in blood serum | 270 | |

Hexabrominated diphenyl ethers
Brominated fire retardants used in foam and plastics. Break down into more toxic and persistent forms in the environment. Withdrawn from the market in the U.S. in 2005.
- level found: 1.93 ng/g (lipid weight) in blood serum
- Low vs 116 tested in EWG/Commonweal studies (22nd %ile)

Pentabrominated diphenyl ethers
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 They were withdrawn from the market in the U.S. in 2005.
