Can flame retardant chemicals in house dust affect your child's behavior?

What's actually in it

Organophosphate ester (OPE) flame retardants and plasticizers are in furniture cushions, electronics, carpet padding, and building insulation. These chemicals slowly escape from products and settle into household dust. Young children are the most exposed because they play on the floor, put things in their mouths, and breathe closer to where dust collects.

These chemicals are designed to be stable and long-lasting in products. That same stability means they hang around in your home for months.

What the research says

A 2026 study in Environ Health Perspect measured OPE levels in household dust and compared them to children's behavior as reported by parents using the Child Behavior Checklist (CBCL), a standard tool that evaluates emotional, social, and behavioral functioning.

Children in homes with higher OPE levels in the dust scored worse on behavioral measures. The study found links to attention problems, anxiety, and aggressive behavior. These effects held up even after adjusting for family income, parent education, and other factors.

The study was nested inside a larger birth cohort, giving the researchers long-term data to work with. The behavioral connections were clearest for specific OPE chemicals commonly used in polyurethane foam furniture and electronics.

Regular HEPA vacuuming, damp mopping, and frequent handwashing before meals can lower dust exposure. When buying new furniture, ask whether it meets flammability standards without added chemical flame retardants.
