Can organophosphate flame retardants in air pollution be linked with sleep problems in children?

What OPEs are

Organophosphate esters (OPEs) are chemicals used as flame retardants and plasticizers. They can be found in some foam, electronics, plastics, and indoor dust.

Kids can be exposed through dust and air, especially close to floors and soft materials.

What the research says

A 2026 study in Toxics looked at 110,169 children age 6 to 18 in the Pearl River Delta region of China. The researchers measured PM2.5-bound OPEs and used a validated sleep questionnaire.

Higher OPE mixture exposure was linked with higher odds of several sleep disorder domains. The strongest individual signals included TDCIPP and TEHP with short sleep duration and TPHP with overall sleep disorder.

This study found links. It does not prove one item in a bedroom causes sleep problems.

What to do at home

Keep bedroom dust low with wet cleaning. Wash kids' hands before bed. When buying new sleep-space items, choose simple materials such as organic cotton when you can.
