Inhaling flame retardants on morning commute: Study

A study published in Environmental Science & Technology reveals that the air inside cars contains harmful flame retardant chemicals, especially on hot days. Researchers tested 101 cars from 2015 or newer and found flame retardants in all of them, with 99% containing TCIPP, a potentially cancer-causing compound. Seat foam was identified as the primary source, and warmer weather was linked to higher concentrations due to increased off-gassing. Lead author Rebecca Hoehn from Duke University emphasizes the significance of this issue for public health, particularly for drivers with longer commutes and child passengers.

While some flame retardants like PBDEs have been phased out, others, including organophosphate ester flame retardants, are still used in various products. These chemicals have been associated with negative health impacts, including reproductive problems and cancer. Experts advocate for updating flammability standards to reduce the use of flame retardants in vehicles, similar to California's approach for furniture and baby products.
