A recent study published in the peer-reviewed journal Environmental Science and Technology sheds light on a concerning issue: the presence of carcinogenic chemicals in Americans’ cars. The study, titled “Flame Retardant Exposure in Vehicles Is Influenced by Use in Seat Foam and Temperature,” highlights the risks associated with exposure to flame retardants commonly found in vehicle interiors.
According to the research, these flame retardants, including polybrominated diphenyl ethers (PBDEs), alternative brominated flame retardants (BFRs), and organophosphate ester flame retardants (OPEs), pose serious health threats. From developmental neurotoxicity to thyroid hormone dysregulation and cancer, the implications of exposure are alarming.
The use of flame retardants in vehicles dates back to the 1970s when the National Highway Traffic Safety Administration (NHTSA) mandated their inclusion to meet federal flammability standards. However, these chemicals, often added in a non-chemically bound form, can become airborne and settle on surfaces, posing a risk to occupants.
Of particular concern are individuals with lengthy commutes or those who drive professionally, as they may face higher exposure levels. Additionally, children, who inhale more air per kilogram of body weight than adults, are at increased risk, especially during extended periods in vehicles.
These findings underscore the importance of addressing flame retardant exposure in vehicles, particularly for those who spend significant time on the road. Strategies to mitigate exposure and reduce associated health risks are crucial for safeguarding public health.
