Scientists have discovered that carcinogenic chemicals are present in the cars Americans drive. However, simple measures may lower the risk of exposure to these harmful substances. In a new study published by “Environmental Science and Technology” titled “Flame Retardant Exposure in Vehicles Is Influenced by Use in Seat Foam and Temperature”, researchers reveal that chemicals from flame retardants in vehicles can cause various health problems, including developmental neurotoxicity, thyroid hormone dysregulation and cancer.
There are varying types of chemicals in flame retardants, which include polybrominated diphenyl ethers (PBDEs), present in cars until the early 2000s, and alternative brominated flame retardants (BFRs), and organophosphate ester flame retardants (OPEs). Flame retardants are required by the federal government to be included in vehicles, mandated by the National Highway Traffic Safety Administration (NHTSA) in the 1970s. They are used in electronics, furnishings, and building materials to meet safety standards.
People who have professional driving jobs or those who have lengthy commutes may potentially be at higher risk due to the chemicals. The report suggests that children could be at a higher risk as well due to their higher respiratory rates compared to adults.
It is suggested that people in hotter states could be at a greater risk due to increased ventilation of the harmful chemicals. However, researchers recommend measures such as rolling down car windows, switching off the AC, and parking in covered garages to help limit exposure. They further suggest that the most significant reduction in exposure would come from significantly reducing the amount of flame retardants added to personal vehicles.
