What has replaced PBBs as a flame retardant today?
What has replaced PBBs as a flame retardant today?
Contemporary FRs, including polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), and tetrabromobisphenol A (TBBPA), replaced PBBs and PCBs.
Are brominated flame retardants still used?
BFRs belong to a large group of organohalogen chemicals. They are highly persistent, bioaccumulative and cause adverse effects in humans and wildlife. Although some BFRs are banned or voluntarily withdrawn from usage by the manufacturer, emerging and existing BFRs continue to be used in industrialized countries.
How do you prevent brominated flame retardants?
Top Tips for Avoiding Toxic Flame Retardants at Home
- Check furniture labels. When shopping for furniture, consumers should CHOOSE furniture labeled “CONTAINS NO ADDED FLAME RETARDANTS.”
- Check kids’ product labels.
- Avoid kids’ products made with polyurethane foam.
- Dust and wash hands regularly.
Are brominated flame retardants banned?
Brominated flame retardant chemicals, banned in the U.S. since 2004, still pollute the bodies of newborn American babies, according to a new study from Indiana University scientists. Polybrominated diphenyl ethers, or PBDEs, were once widely used in products including furniture foam and electronics.
Where are organophosphorus flame retardants found?
3.3. 1. Detection of Organophosphate Flame-Retardant Content in Biological Samples. Organophosphate esters (OPEs) were found in human blood, milk, and placenta, and in fish and their eggs, which means OPFRs are very likely to be transferred to the next generation [3,131].
Why is phosphorus flame retardant?
When phosphorus is heated it will react, and form a polymeric form of phosphoric acid. This acid causes a char layer, which shields the material from oxygen, in that way preventing the formation of flammable gasses.
Did Mountain Dew get rid of brominated vegetable oil?
Our ruling: Partly false. The Facebook post’s claim that brominated vegetable oil is no longer in Mountain Dew is true. The use of brominated vegetable oil has declined over the years as major companies have removed the additive from their drinks in favor of other emulsifiers.
Why is PBDEs banned?
The compounds, polybrominated diphenyl ethers, or PBDEs – were banned after evidence emerged that they were doubling in women’s breast milk every five years. Studies suggest that PBDEs can disrupt thyroid hormones in pregnant women and newborns. Thyroid hormones are important for brain development.
What states have banned flame retardants?
Antimony trioxide newest chemical to be added to growing list of flame retardant bans

Should I be worried about flame retardants?
Data suggests that exposures to other organophosphate flame retardants could affect thyroid hormone regulation and male fertility. Toxicology studies also suggest these compounds may be related to obesity and may affect children’s brain development.
