Study Reveals Cancer-Causing Chemicals Lurking in Car Cabin Air

In a recent study published in Environmental Science & Technology, researchers have sounded the alarm on a concerning discovery – cancer-causing chemicals are pervading the air inside our cars. With 101 vehicles tested across 30 US states, the findings underscore a significant public health risk, urging immediate attention from manufacturers and regulators alike.

The study found that a staggering 99% of the cars examined contained tris(chloropropyl)phosphate (TCIPP), a flame retardant under scrutiny by the U.S. National Toxicology Program for its potential carcinogenic properties. Even more worrisome, additional cancer-causing flame retardants, TCEP and TDCIPP, were prevalent in most vehicles tested.

Lead researcher Rebecca Hoehn emphasized the gravity of the situation, noting that the average driver spends about an hour in their car daily, exposing them to these harmful substances. Vulnerable populations, such as children and those with long commutes, face heightened risks due to increased inhalation rates and prolonged exposure.

The study points to seat foam as the primary source of these carcinogenic substances, tracing back to outdated safety regulations from the 1970s. Initially incorporated for safety compliance, flame retardants need updates, raising concerns over obsolete standards.

Patrick Morrison, director of the International Association of Fire Fighters’ safety division, highlighted the ineffectiveness of these chemicals in preventing fires, emphasizing the need for regulatory updates to ensure public safety without compromising health.

Lydia Jahl, a senior scientist at the Green Science Policy Institute, outlined practical steps to mitigate risks, including parking in shaded areas, limiting time spent in parked cars, and using natural materials for car accessories. However, she emphasized the urgent need to reduce the use of flame retardants in vehicles to eliminate cancer risks associated with daily commutes.

The study serves as a wake-up call for both manufacturers and regulators. The imperative now lies in exploring safer alternatives to these harmful chemicals and implementing stringent measures to safeguard the health and well-being of drivers and passengers alike.
