How harmful is PBDEs (polybrominated diphenyl ethers)?

PBDEs (polybrominated diphenyl ethers) is rated MODERATE exposure concern (5.3/10) on the Read Off Label scale, derived from strong evidence of medium harm magnitude and low-moderate exposure prevalence.

Bottom line

Read Off Label rates PBDEs (polybrominated diphenyl ethers) a MODERATE exposure concern (5.3/10) based on strong evidence of medium harm magnitude and low-moderate exposure prevalence.

This entry describes an exposure rather than an added intervention.

What the evidence says

California TB117 furniture flammability standard drove huge US PBDE use 1975-2013. Body burdens in Americans were 10x Europeans before phase-out. Household dust is the major continued exposure route. Replacement chemicals have 'regrettable substitution' concerns. Update Jul 2026: the Ninth Circuit (May 13, 2026) vacated and remanded the EPA's 2024 decaBDE rule as unsupported by the record, sending recycling/disposal/wastewater exposure-pathway provisions back for further rulemaking -- the regulatory status is temporarily back in flux.

Mechanism

Brominated flame retardants added to furniture foam, electronics, textiles; chemically similar to PCBs; endocrine disruptors, neurodevelopmental toxicants; largely phased out of new products since 2004-2013

Reported exposure / mitigation context

Household-dust exposure can be reduced by damp dusting and HEPA vacuuming and lower contact with pre-2014 furniture foam and handwashing
