Summary

PBDE 209 (Deca) is the only form of PBDEs that is unregulated in the United States. Deca is widely used in television and computer housings, cell phones and electronic products. There is growing evidence that Deca breaks down in the environment to more persistent and toxic forms, and that it is directly impacts learning, memory and behavior in laboratory animals.




PBDE-209

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

PBDE-209 has been found in 55 of the 138 people tested in EWG/Commonweal studies.
