Recent research points towards a presence of cancer-causing chemicals in the enclosed spaces of vehicles, potentially threatening the health of drivers and passengers. The study, published in Environmental Science & Technology, has created a buzz about the hidden dangers that might be introduced into vehicles. Dr. Ken Speath, division chief and medical director at Northwell Health, reminds people to be aware of the air quality in all environments, including cars.
In a study of 101 US-based, post-2015 model cars, harmful flame-retardant chemicals were found, some of which are suspected to cause cancer and neurological issues. Seat foam was a primary focus, but other materials may also contain these chemicals.
The exposure risk is higher given that the average driver reportedly spends an hour per day in a car. Children are more susceptible as they breathe more air per body weight than adults. The chemicals detected include TCIPP, TDCIPP, and TCEP, all subject to ongoing toxicity investigations.
To tackle these issues, researcher Rebecca Hoehn suggests ventilation as a simple method to reduce concentrations of harmful substances. She also suggests parking in the shade or a garage to limit the heat-induced release of flame retardants. For long-term mitigation, reducing the amount of flame retardants used in vehicle production could significantly lower exposure risk. The study further encourages regulatory agencies and vehicle manufacturers to take action.
However, vehicles are not the only source of toxins. Common environmental health triggers, such as mold, can thrive in wet conditions, particularly with leaking air conditioners or spilled drinks in cars, flags Stephen Showalter, a home inspector and air consultant.
