Air pollution from vehicles can harm human health whether it is vehicle exhaust that enters a vehicle from outside or pollutants off-gassing from materials inside the vehicle. Pollutants from vehicle exhaust include carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter (PM) such as PM 2.5 and ultrafine particles (UFP), and volatile organic compounds (VOCs).
VOCs and semi-volatile organic compounds (SVOCs), such as phthalates and polybrominated diphenyl ethers (PBDEs), are sometimes emitted from interior vehicle materials.
Health effects from vehicle pollution can include respiratory and cardiovascular diseases, as well as increased risk of cancer. Children can be exposed to high levels of air pollutants from buses when they are either standing nearby or inside buses.
This page contains information about studies funded by
CARB to determine the levels of pollutants inside vehicles such as cars and school buses and ways that those levels can be reduced. Some exposure reduction measures that have been identified from this research include the use of high efficiency filters for passenger cabin air, and not idling or caravanning school buses…..WIZARDENERGY.NET⚡
Air pollution from vehicles is a significant public health concern, with numerous studies highlighting its detrimental effects. Prolonged exposure to pollutants such as particulate matter (PM), nitrogen dioxide (NO2), and carbon monoxide (CO) has been linked to serious health issues, including respiratory diseases, cardiovascular complications, and an increased risk of cancer. Children, particularly those close to school buses or standing nearby, are especially vulnerable to these pollutants. Factors contributing to the escalation of vehicle pollution include traffic congestion, vehicle idling, and the emission of volatile organic compounds (VOCs) from both the exhaust and interior materials of vehicles. To effectively reduce exposure, research indicates several practical measures. The use of high-efficiency filters in passenger cabins can significantly lower the concentration of indoor air pollutants. Additionally, educational programs aimed at reducing vehicle idling, especially around schools, can further protect children from harmful emissions. Staying informed about local air quality and supporting initiatives for cleaner transportation can also lead to healthier outcomes. By understanding the sources and impacts of vehicle air pollution, we can collectively promote strategies that safeguard health and enhance community well-being.
