A study published in the journal Environmental Science & Technology found that vehicles are significant sources of human exposure to potentially harmful flame retardants. Drivers who spend a considerable amount of time in their cars, such as commuters and full-time vehicle drivers, are at higher risk of exposure, with children being particularly vulnerable. The study involved placing silicone bands in cars to measure chemical levels, noting that concentrations were higher in summer due to increased release from car materials in hot temperatures.
Flame retardants were detected in every car tested, with TCIPP being found in 99% of the cars. This chemical releases toxic fumes when heated, potentially posing health risks to individuals exposed to them. While the specific health effects of breathing in flame retardants are not yet fully understood, previous studies have indicated carcinogenic activity in animals. Researchers are calling for a re-evaluation of federal flammability standards for vehicles, similar to the revision of standards for upholstered furniture in 2021 to eliminate flame retardants.
The National Highway Traffic Safety Administration, responsible for setting these standards, did not provide a response regarding the study’s findings. The International Association of Fire Fighters expressed concern about the risks posed by flame retardants in vehicles, emphasizing the potential dangers when these chemicals are exposed to fire. Recommendations from the study researchers include rolling down car windows to ventilate the interior and washing hands after being in a car to reduce exposure to flame retardants.
In conclusion, the study sheds light on the presence of harmful flame retardants in vehicles and the potential risks they pose to occupants, especially children. Further research and a re-evaluation of flammability standards are needed to ensure the safety of individuals exposed to these chemicals. Drivers are advised to take precautions such as ventilating car interiors and washing hands to minimize exposure to flame retardants found in car materials. The findings underscore the importance of understanding and addressing potential health risks associated with everyday exposures to toxic chemicals in our environment.
