New Car Smell Could Harm Your Health

It could be linked to cancer-causing agents.

Recent research has shed light on a concerning aspect of the beloved “new car smell” that many consumers associate with their vehicle purchases. It turns out that this distinctive scent might not be as harmless as it seems. Studies have revealed that the source of this odor is often flame retardant chemicals present in various components of cars, particularly in seat foam. These chemicals, added to meet outdated federal flammability standards, have been found to release harmful carcinogens into the air within the vehicle cabin, posing significant health risks to occupants.

In a comprehensive study published in Environmental Science & Technology, researchers investigated 101 cars manufactured in 2015 or later across the United States. The findings were alarming, with nearly all vehicles containing flame retardants. Tris (1-chloro-isopropyl) phosphate (TCIPP), one of the flame retardants scrutinized for its potential carcinogenic properties, was detected in 99% of the cars tested. Moreover, other known carcinogens such as tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) and tris (2-chloroethyl) phosphate (TCEP) were also prevalent.

The study emphasized the health risks associated with prolonged exposure to these flame retardants, particularly for individuals with lengthy commutes and children who are more susceptible to inhaling contaminated air. Furthermore, the research highlighted how higher temperatures can exacerbate the release of these chemicals from seat foam and other interior components, leading to elevated concentrations in warmer climates.

While flame retardants were initially introduced into seat foam to comply with federal flammability standards established in the 1970s, doubts have been raised about their effectiveness in improving fire safety. This is especially concerning given the documented adverse health effects linked to flame retardant exposure. Concerns have been voiced by firefighters, who fear that these chemicals may contribute to increased cancer rates within their profession.

In light of these findings, there have been calls for updated flammability standards that do not rely on flame retardant chemicals. California has already taken steps in this direction by implementing alternative standards for furniture and baby products, proving that fire safety can be maintained without the use of these harmful substances. Researchers stress the importance of reducing the use of flame retardants in automobiles to safeguard the health and well-being of both drivers and passengers, particularly children.
