Do home dust samples contain high levels of flame retardants?

What's actually in it

Your home dust is often a collection of chemicals that have escaped from your furniture, electronics, and building materials. This includes organophosphate ester flame retardants and plasticizers. These chemicals don't stay inside your products: they shed, break down, and settle into the dust on your floors, shelves, and carpets.

Because these chemicals are not chemically bound to the products they are added to, they easily move into the air and dust of your living space. When you or your children breathe or touch this dust, you are exposed to these substances.

What the research says

Peer-reviewed research confirms that these chemicals are a real concern for indoor health. A 2026 study in J Expo Sci Environ Epidemiol found that exposure to organophosphate ester flame retardants and plasticizers in house dust is linked to negative outcomes on the Child Behavior Checklist.

The risks extend beyond behavior. A 2026 study in Environ Pollut highlights that prenatal exposure to these same flame retardants is associated with impacts on child cognition. Furthermore, a 2026 study in Environ Res found that gestational exposure to these chemicals is linked to changes in child growth, including weight, height, and body mass index at ages 2 to 10.

Other types of flame retardants are also a problem. A 2026 study in Sci Total Environ identified a clear association between brominated flame retardants and the diagnosis or symptoms of allergies in a nationally representative sample of people in the US.
