Some of the worst flame retardant chemicals were banned in the United States starting in 2004, when manufacturers agreed to stop making penta-BDE and octa-BDE, two types of polybrominated diphenyl ethers (PBDEs). Yes, several flame retardants are banned in the US and other countries, but the chemicals stick around in older products, dust, and even breast milk for decades after the bans took effect. Deca-BDE followed years later, with California moving to prohibit two PBDE flame retardants in furniture and other goods.
We work with fabrics and fire safety every day at Levitex, and the question we hear most is whether a ban actually means the chemical is gone. It doesn’t. New research has found flame retardant residues in breast milk years after the original PBDE chemicals were phased out, since replacement chemicals with similar structures moved in to take their place, as reported by NPR. Choosing furniture, fabric, and baby products with fewer added chemicals still matters, ban or no ban.
Where are flame retardants found?
Flame retardants show up in almost anything designed to resist fire, from couch cushions to phone cases. They’re mixed into furniture foam, electronics, textiles, and plastics to slow down how fast a fire spreads.
Common household items with these chemicals include:
- Upholstered furniture and mattresses
- Printed circuit boards and other electronics
- Plastic casings surrounding electronics like TVs
- Child care articles, including mattress pads and other children’s products
- Building insulation and other construction products
- Car seats, textiles, and thermal insulation
Plastics like ABS, HIPS, EPS, and XPS often contain brominated polystyrene or similar additive flame retardants to meet flammability rules. The EPA notes that baby products such as nursing pillows, crib mattresses, strollers, and changing pads have historically carried these chemicals too.
Household products and consumer products made from foam or soft plastic are the most likely places to find them. If you’re picking fabric for furniture or clothing, it helps to know what flame retardant treated fabric actually involves before buying.
How are people exposed to flame retardants?
People get exposed to flame retardants mainly through house dust, food, and everyday contact with treated products. These chemicals aren’t chemically bonded to the materials they’re added to, so they escape into the air and settle into dust over time.
Ingestion happens through more paths than most people expect:
- Breathing in household dust
- Eating contaminated food, including fish, meat, and milk
- Drinking water near industrial or waste sites
- Skin contact with treated furniture, clothing, or electronics
Diet plays a bigger role than people think. Flame retardants build up in the food chain, and they’ve been detected in fish, meat, and dairy, according to ScienceDirect. Breast milk is another exposure route, which puts infants at higher risk during a critical stage of development.
Children face the highest exposure levels of any age group. Young kids crawl on floors, touch dusty surfaces, and put their hands in their mouths constantly, giving flame retardant particles a direct path into their bodies.
Occupational exposure adds another layer of risk for people who work with electronics, foam manufacturing, or furniture production. Human exposure studies consistently find these chemicals in blood and urine samples across nearly every group tested, regardless of age or location.
Why are flame retardants considered so dangerous?
Flame retardants are dangerous because many of them don’t break down and keep building up in bodies, wildlife, and the environment. Scientists classify several of these compounds as persistent organic pollutants, or POPs, meaning they resist natural breakdown for years or even decades.
Here’s what makes them a public health concern:
- They accumulate in human tissue and fatty foods over time
- They travel through air and water to reach remote places, including polar regions and deep oceans
- They’ve been linked to reproductive harm and nervous system damage
- Long-term exposure is tied to a higher risk of certain cancers
A 2024 study covered by CNN linked common flame retardants called PBDEs to cancer deaths in people for the first time. This is one of the clearest signs yet that the health risks aren’t just theoretical.
Persistent organic pollutants like PBDEs and PBBs don’t stay put once they’re released. Rivers, wildlife, and even remote ecosystems show contamination from chemicals that were supposedly phased out years ago, based on findings from Inside Ecology. Their toxicity profile is a major reason regulators keep expanding restrictions on brominated and halogenated flame retardants, even as replacement chemicals raise similar questions.
Is It Wise to Choose Flame Retardants?
Flame retardants make sense in specific high-risk situations, but for most household products, safer alternatives usually offer better protection without the same health trade-offs. These chemicals do slow flame spread and buy extra time to escape a fire. They also release more smoke and toxic gases when they burn, which creates its own danger.
Firefighters face a particular risk here. Chemicals released when flame retardants burn have been connected to elevated cancer rates in firefighting crews, based on toxicology research from Green Science Policy Institute.
Risk assessment for these chemicals is still catching up. Data gaps remain around many replacement compounds, since regulators often study one chemical at a time while manufacturers move on to the next similar substitute. The EPA’s fact sheet on flame retardants points to ongoing work on data needs and open public comment periods for evaluating these risks.
Consumer product safety improves when manufacturers pick safer alternatives from the start. Options include:
- Early-detection smoke alarms
- Self-extinguishing cigarettes
- Naturally fire-resistant materials in furniture and textiles
For shoppers who want to compare options directly, it helps to look at natural fire retardant materials or check the best types of flame retardant fabrics before buying furniture or clothing. Recycled feedstock in electronics and furniture can also reintroduce banned chemicals if manufacturers don’t screen materials carefully, which is worth asking about before you buy.
Conclusion
Flame retardant bans in the US have removed some of the worst chemicals from new products, but older items, dust, and even breast milk still carry traces of them years later. Exposure happens through food, dust, and everyday contact with treated furniture and electronics, and children face the highest risk because of how they interact with their surroundings.
The health concerns are well documented, from reproductive harm to links with cancer, and regulators are still working to close data gaps on newer replacement chemicals. Choosing furniture and fabrics with safer, well-tested materials remains one of the most practical ways to lower everyday exposure, whether or not a specific chemical carries an official ban.
