polybrominated diphenyl ethers

(pōl″ē-brōm′ĭ-nāt″ĕd),

PBDE

A class of chemicals used as flame retardants. They are chemically related to polychlorinated biphenyls and are thought to have similar biological toxicity. They have been found in streams, marine animals, human fetuses, and human breast milk.

Since polybrominated diphenyl ethers (PBDEs) and hBcD (and ~20% of the production of TBBP-A) are blended physically rather than bonded chemically to polymeric materials, they migrate into the environment where their persistence and bioaccumulative characters lead to contamination of humans [4].

During the past decade both animal and human studies have supported an association between polybrominated diphenyl ether (PBDE) flame retardants and neurobehavioral/neurodevelopmental disorders, particularly following in utero and postnatal exposure (Costa and Giordano 2007; Darnerud et al.
Thus, distribution of polybrominated diphenyl ethers (PBDEs) will vary with the particle size of dust and the spatial position of settled dust, as well as the location of PBDE sources, such that PBDE levels in settled dust on the floor will be different from those of settled dust above the floor (Bjorklund et al.
