99% of tested cars contain cancer-causing flame retardants (TCIPP), linked to car interiors, under investigation by the US National Toxicology Program.

A study reveals that car interiors contain cancer-causing flame retardants, with 99% of tested cars containing tris (1-chloro-isopropyl) phosphate (TCIPP), under investigation by the US National Toxicology Program. These chemicals are released from materials and seat foam, added to meet outdated flammability standards. Researchers warn that reducing flame retardants in cars could lower cancer risks for drivers and passengers.
