A recent study reports that 99% of cars have the toxic flame retardant TCIPP in the cabin air, with higher levels in summer due to heat.

Flame retardants are used in car seat foam to meet safety standards but are deemed unnecessary inside vehicles.

Public health concerns arise for individuals with long commutes and children, as well as for firefighters who may be exposed to these chemicals.

To mitigate exposure, the study suggests opening car windows, parking in shade, and advocates for reducing flame retardants in cars.

The study calls on the U.S. National Highway Traffic Safety Administration to revise flammability standards to eliminate the need for flame retardants inside vehicles.

The prevalence of flame retardants in car interiors is a widespread issue, affecting not only the US but also European automotive industries.
