A toxic environment increased by heat
Summer heat can transform car interiors into a veritable incubator for certain toxic gases, researchers warn. A recent study, published in the journal “Environmental Science & Technology”, highlights the increased risk of release of a potentially carcinogenic substance, adenosine triphosphate (TCIPP), present in flame-retardant materials used in many interior components cars.
Used to increase the fire resistance of foams used in seats and other parts of the passenger compartment, TCIPP is released into the air under the effect of heat, endangering the health of passengers.
Increased risks for regular users
Scientists from Duke University, UC Berkeley and the University of Toronto observed that in a normal climate, TCIPP concentrations are comparable to those found in a typical home.
However, as temperatures rise, these concentrations soar, posing a significant risk, particularly for professional drivers and families with children who spend a lot of time in their vehicles.
Potentially serious health consequences
The seriousness of exposure to TCIPP should not be taken lightly. The United States Department of Health has classified this substance as a possible carcinogen. Animal tests have shown that exposure to this compound is linked to the development of liver and uterine tumors. Replacing TDCIPP, another flame retardant already known to have carcinogenic effects in California, TCIPP may not be a safer alternative.
Recommendations for reducing exposure
Faced with these worrying findings, researchers recommend several measures to limit the risks. Among these, maintaining a moderate indoor temperature and parking vehicles in the shade when possible are essential to reduce the thermal decomposition of flame retardants.
In addition, it is strongly recommended to regularly ventilate the interior of cars by opening the windows, especially after parking under the sun, to dilute the concentration of these harmful compounds in the ambient air.
In conclusion, As car manufacturers and public health authorities seek to make vehicles safer in the event of a fire, it becomes imperative to strike a balance with the toxicity of the materials used, to ensure the overall safety of users.
