New Study: Cancer-Causing Flame Retardants in Car Cabin Air

United States of America
Flame retardants linked to neurological and reproductive harms.
Highest levels of toxic chemicals found in summer due to warmer weather causing higher release from car materials.
New study published in Environmental Science & Technology finds 99% of cars contain cancer-causing flame retardant TCIPP, and two more carcinogenic flame retardants TDCIPP and TCEP.
Opening windows, parking in shade or garages may help reduce exposure.
New Study: Cancer-Causing Flame Retardants in Car Cabin Air

A new study published in Environmental Science & Technology has found that people are breathing in cancer-causing chemicals while in their cars. The source of the cancer-causing compounds in cabin air is seat foam, which contains flame retardants to meet an outdated flammability standard with no proven fire-safety benefit. The study analyzed the cabin air of 101 electric, gas, and hybrid cars with a model year between 2015 and 2022 and discovered that 99% of them contained the flame retardant TCIPP, which is under investigation by the US National Toxicology Program as a potential carcinogen. Two more flame retardants, TDCIPP and TCEP, which are considered carcinogenic, were also found in most cars. Flame retardants are linked to neurological and reproductive harms as well. The levels of toxic flame retardants were highest in the summer due to warmer weather causing a higher release of chemicals from car materials. Researchers suggest that opening car windows and parking in the shade or garages may help reduce exposure to toxic flame retardants. Lydia Jahl, a study author, emphasized that the real solution is reducing the amount of flame retardants added to cars in the first place.

  • Fallacies (85%)
    The article contains a few informal fallacies and an appeal to authority. It presents the findings of a study as evidence for the presence and dangers of flame retardant chemicals in cars without providing direct quotes from the study itself. Additionally, it suggests that certain actions can reduce exposure to these chemicals, which is an argument from authority based on expert opinion.

  • Deception (80%)
    The article reports on a study that found high levels of cancer-causing flame retardants in car cabin air. The author provides quotes from experts expressing concerns about the health risks and calls for action to reduce exposure. However, the author also makes editorializing statements such as 'considering the average driver spends about an hour in the car every day, this is a significant public health issue.' and 'commuting to work shouldn’t come with a cancer risk.' These statements are not factual and add emotional manipulation to the article. The author also selectively reports details of the study, focusing only on the cancer-causing properties of the flame retardants without mentioning any potential benefits or context. Additionally, while sources are mentioned in the article, they are not directly quoted or linked within the text.

  • Deception (70%)
    The article does not make any editorializing or pontification statements by the author. However, it does use emotional manipulation by describing the potential health risks of flame retardant chemicals as 'toxic' and 'potentially harmful'. The article also uses selective reporting by only mentioning the potential negative effects of flame retardants without discussing their purpose or benefits. Additionally, there is a lack of disclosure regarding the sources for some statements in the article.
    • Researchers detected flame retardants in every car tested and specifically found TCIPP – which the National Institutes of Health says releases toxic fumes ‘when heated to decomposition’ – in 99% of the cars tested.
    • Singla told CBS News she ‘never realized there could be toxic chemicals inside her car.’
    • For now, the study’s researchers recommend rolling car windows down when you first get in to let the air out and to wash your hands after being in a car.
  • Fallacies (95%)
    The article contains an appeal to authority when it mentions the study published in the journal Environmental Science & Technology and quotes Lydia Jahl, a senior scientist at the Green Science Policy Institute. The article also uses inflammatory rhetoric by stating that 'researchers detected flame retardants in every car tested' and 'it was found that the concentration of those chemicals was two to five times higher in the summer compared to the winter'. However, no specific fallacies were identified as there are no false statements or invalid reasoning presented.

  • Deception (5%)
    The article makes several statements that could be considered deceptive or misleading. First, the title and body of the article imply that all cars contain cancer-causing chemicals due to seat foam, but it is not clear from the study data provided in the article how many cars contained levels of these chemicals above a certain threshold that would pose a health risk. Second, while the article mentions that flame retardants have been added to seat foam to meet requirements set by NHTSA's Federal Motor Vehicle Safety Standard 302, it does not mention that these requirements were put in place to reduce the risk of fires in cars. This omission could be seen as an attempt to downplay the importance of flame retardants in car safety. Third, while the article mentions that people can reduce their exposure to toxic flame retardants by opening their car windows and parking in the shade or garages, it does not mention that these measures may not be effective in reducing exposure levels significantly. Lastly, while the article quotes experts expressing concerns about the health risks of flame retardants and calling for updates to NHTSA's flammability standard, it does not provide any context about the potential benefits or drawbacks of such a change.
    • Researchers found that 99% of the cars contained a flame retardant called TCIPP, which is currently under investigation by the U.S. National Toxicology Program as a potential carcinogen.
    • Drivers and passengers are breathing in potentially cancerous chemicals while in their cars, a new study finds.
    • People can reduce their exposure to the toxic chemicals by opening their car windows and parking in the shade.
