Children's Health and Polybrominated Diphenyl Ether (PBDE)

On this page:


Overview

Brominated fire retardants (BFRs) are widely used in a number of consumer products to prevent fire-related injury and property damage. Recently it has been shown that polybrominated diphenyl ethers (PBDEs), a type of BFR, are persistent in the environment and capable of accumulating in the tissues of animals, fish, and humans.

Whether PBDEs pose a health risk to humans is a major area of current research. These pages are intended to provide more information about research projects underway in the Pacific Southwest. Several reports are available, as well as information about the recent ban of PBDEs in California.

  • Environmental Working Group
    Results from a study of PBDEs in breast milk of 20 new mothers across the United States. Numerous links and additional information about PBDEs are also available.
  • Links to additional key studies (within EWG report)
  • Toxic Fire Retardants Building up in San Francisco Bay Fish
    In the fall of 2002, EWG researchers collected 22 fish from six of the most commonly eaten species at 10 locations around San Francisco Bay and tested for PBDE levels. EWG also tested for PBDEs in fish samples archived from 1997, and found that in five years, levels of the chemicals had increased in four of six species tested.

Policy

In response to concern about the rising concentration of PBDEs in the environment and high levels in the breast milk of Californian women, California legislators passed a bill (A.B. 302, Wilma Chan) to phase out penta- and octa-PBDEs from consumer products by January 1, 2008.
