Research Findings

A recent study published in Environmental Science & Technology reveals that people are exposed to cancer-causing chemicals while inside their cars.

Study Scope

Researchers examined cabin air from 101 electric, gas, and hybrid cars manufactured between 2015 and 2022.

Prevalence of Flame Retardants

Almost all cars (99%) contained TCIPP, a flame retardant being investigated as a potential carcinogen by the US National Toxicology Program. Additionally, most cars also had TDCIPP and TCEP, both known carcinogens.

Health Risks

The flame retardants identified are not only carcinogenic but also linked to neurological and reproductive harm, raising significant public health concerns.

Duration of Exposure

Lead researcher Rebecca Hoehn highlights the issue’s gravity, especially for drivers with longer commutes and child passengers who inhale more air pound for pound than adults.

Seasonal Variation

Toxic flame retardants reached their highest levels in summer, attributed to increased chemical release from car materials due to heat.

Source of Contamination

Seat foam emerges as the primary source of cancer-causing compounds in cabin air, with manufacturers adding these chemicals to meet outdated flammability standards.

Calls for Action

Experts like Patrick Morrison advocate for updating flammability standards without the use of harmful chemicals, stressing the need for intervention from regulatory bodies like NHTSA.

Mitigation Strategies

While opening windows and parking in shaded areas may reduce exposure, researchers emphasize the urgency of reducing flame retardant use in vehicles to safeguard public health, especially during daily commutes and school transportation.
