BDE-47

Older foam furniture, mattresses, car seats, and some electronics that used penta‑BDE mixtures; it migrates into indoor dust over time [1][2].

Breathing or swallowing dust at home, hand‑to‑mouth contact (especially in children), eating fatty fish/meat/dairy, and through breast milk; higher exposures can occur in recycling or foam‑handling jobs [1][2][3].

Linked to learning/attention problems, thyroid hormone disruption, and reproductive effects; it bioaccumulates in people and wildlife and breaks down slowly in the environment [1][2].

Pregnant people, infants and toddlers, those with older foam furniture, and workers in e‑waste or foam industries [1][2][3].

Wet‑dust and mop, use a HEPA vacuum, wash hands before eating (children too), repair/replace crumbling foam with PBDE‑free materials, improve ventilation, choose PBDE‑free products, and vary diet/trim fat from meats [1][2].
