Can organophosphate flame retardants in house dust cause behavior problems in children?

What's actually in it

Organophosphate esters (OPEs) are flame retardants and plasticizers added to furniture foam, electronics, and building materials. Unlike chemicals that bond permanently to materials, OPEs migrate out continuously. They end up in house dust — the fine particles that settle on floors, furniture, and children's toys.

Babies and toddlers are especially exposed because they crawl and play on the floor, put objects in their mouths, and have more hand-to-mouth contact than adults. Their developing brains are also more sensitive to neurotoxic chemicals.

What the research says

A 2026 study in J Expo Sci Environ Epidemiol measured OPE concentrations in house dust samples from 839 Canadian families and tracked children's behavior using the Child Behavior Checklist. Higher OPE levels — specifically TCIPP and TPHP — were linked to more anxious, withdrawn, and attention-problem behaviors.

The association held after controlling for other factors, and effects were seen within the range of real-world household OPE levels, not extreme exposures. These are the same flame retardant chemicals found in most conventional upholstered furniture sold today.

Choose flame retardant-free furniture and mattresses. Vacuum frequently with a HEPA vacuum. Wash children's hands before meals and after floor play. See non-toxic home essentials for safer furniture options.
