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.

  • geometric mean: 28.2 ng/g lipids in blood serum (vs. 26.3 in CDC biomonitoring [1])
      [excludes PBDE-154/PBB-153]
  • found in 2 of 2 people in the group (vs. 2,037 of 2,337 in CDC biomonitoring)
  • found in: Laurie Yung, Conner Adams
1.11ng/g lipids in blood serum314


Total Polybrominated diphenyl ethers (PBDEs)

  • geometric mean: 0.365 ng/g lipids in blood serum (vs. 0.385 in all EWG/Commonweal studies)
  • found in 2 of 2 people in the group (vs. 40 of 40 in all EWG/Commonweal studies)
  • found in: Laurie Yung, Conner Adams
0.11ng/g lipids in blood serum1.95


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.

  • geometric mean: 1.79 ng/g lipids in blood serum (vs. in all EWG/Commonweal studies)
  • found in 1 of 2 people in the group (vs. 37 of 116 in all EWG/Commonweal studies)
  • found in: Laurie Yung
ng/g lipids in blood serum270


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 Withdrawn from the market in the U.S. in 2005.

  • geometric mean: 13.4 ng/g lipids in blood serum (vs. 4.1 in all EWG/Commonweal studies)
  • found in 2 of 2 people in the group (vs. 116 of 116 in all EWG/Commonweal studies)

0.45ng/g lipids in blood serum15.4


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 They were withdrawn from the market in the U.S. in 2005.
