A recent study has cast a spotlight on a disturbing reality: unsuspecting individuals are inadvertently exposing themselves to cancer-causing chemicals while inside their vehicles. Published in Environmental Science & Technology, the research delved into the cabin air of 101 electric, gas, and hybrid cars manufactured between 2015 and 2022, unearthing unsettling findings.
The Startling Discovery
The study’s revelations are nothing short of alarming, with a staggering 99% of the examined cars found to contain a flame retardant known as TCIPP. This compound, currently under scrutiny by the US National Toxicology Program for its potential carcinogenic effects, poses a significant health concern. Furthermore, the majority of vehicles also harbored two additional carcinogenic flame retardants, TDCIPP and TCEP, which have been associated with neurological and reproductive harm.
Expert Insights
Lead researcher Rebecca Hoehn, a toxicology scientist at Duke University, underscored the severity of the situation. She particularly highlighted the heightened risk for individuals with lengthy commutes and young passengers, who are more susceptible to prolonged exposure. Hoehn pointed out that toxic flame retardant levels peaked during the summer months, attributed to heat-induced chemical release from car materials.
Identifying the Culprit
Seat foam emerged as the primary source of these cancer-causing compounds within the cabin air. Car manufacturers incorporate these chemicals into seat foam and other materials to comply with outdated flammability standards, despite lacking substantial evidence of their efficacy in enhancing fire safety.
Advocating for Change
Patrick Morrison from the International Association of Fire Fighters echoed concerns, drawing attention to the elevated cancer rates among firefighters attributed to flame retardant exposure. He urged the US National Highway Traffic Safety Administration (NHTSA) to reevaluate flammability standards and eliminate these harmful chemicals from vehicles.
Mitigating the Risk
While practical measures such as opening car windows and parking in shaded areas or garages can help reduce exposure, the study authors emphasized the urgent need to minimize the use of flame retardants in cars. Commuting and travel should not pose a cancer risk, especially to children. Urgent action is required to safeguard public health and mitigate the hidden hazard lurking within our vehicles.
