A team of scientists has revealed that the source of new car smells could pose health risks to drivers and passengers.
In new Stadypublished this Tuesday in PNAS AssociationThe researchers analyzed carbon dioxide emissions over seven summer days. Volatile organic compounds (VOC) inside a new hybrid electric vehicle.
To measure the levels of these compounds, they used specialized equipment. Temperature monitoring And the Air exchange rates.
The team collected air samples from the driver of the car. 80 in 80 minutesproviding a detailed picture of how VOC concentrations change throughout the day in different weather types.
Volatile organic compounds are a group of Chemicals Which easily turn into vapors or gases at room temperature. In cars, these substances are emitted from various materials such as plastics, synthetic fibers, leather and adhesives.
Some compounds are harmless, while others can cause health problems ranging from headaches and eye irritation to more serious conditions like lung disease.
According to the ResultsThe researchers concluded that formaldehyde, a carcinogen, was the most common VOC in new cars. More than a third The measurements exceeded Chinese air quality standards for vehicle interiors.
In addition, other chemicals of concern were found including: Acetaldehyde And the HexaldehydeBoth are present at levels sufficient to have an effect on human health.
The study focused on a One car It is new, so it cannot represent all types of vehicles or long-term emissions, nor can it represent all types of climates and regions, as it was conducted in Beijing only.
This research highlights the importance of Ventilation in new vehiclesespecially during hot weather, and points to the need for manufacturers to be creative. Materials that emit lower amounts of volatile organic compounds And better climate control systems, which take surface temperature into account.
Finally, the study not only highlights a hidden health problem, but also paves the way for healthier transportation solutions.
