A recent study has raised concerns about the presence of harmful chemicals in the air inside cars, which drivers and passengers are exposed to during their travels. The study conducted by researchers at the Green Science Policy Institute found that almost all cars manufactured between 2015 and 2022 contain a flame-retardant chemical called tris (1-chloro-isopropyl) phosphate (TCIPP). This chemical, known to be potentially toxic, has been linked to adverse health effects such as reduced IQ levels in children and an increased risk of cancer.
The study, published in the Environmental Science and Technology journal, analyzed 101 cars across the United States. It revealed that higher temperatures in summer caused an increase in flame-retardant concentrations due to off-gassing, where chemicals absorbed in materials are released into the air. Samples of seat foam from half of the cars analyzed showed higher concentrations of TCIPP, indicating a correlation between the presence of the chemical in materials and its release into the air.
Exposure to these toxic chemicals poses particular risks to children, whose developing brains and bodies are more susceptible to harm. Increased exposure to flame-retardant chemicals like TCIPP has been associated with reduced IQ levels, learning disabilities, autism, and behavioral issues in children. Additionally, these chemicals, along with others like tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) and tris (2-chloroethyl) phosphate (TCEP), have been linked to neurological, reproductive, and cancer-related health issues.
While laws have been implemented to regulate the use of flame-retardant chemicals in furniture and other products, the automotive industry continues to use these chemicals in vehicles. Although flame-retardants like PBDEs have been restricted due to health concerns, alternatives like TCIPP are still being used in vehicles to meet flammability standards, despite their associated health risks.
The study underscores the need for further research to understand the extent of exposure to flame-retardant chemicals in vehicles and their potential health impacts. In the meantime, the researchers suggest practical measures such as opening windows or parking in shaded areas to reduce exposure. However, they emphasize the importance of reducing the use of flame retardants in cars to mitigate health risks associated with commuting and traveling.
