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⚡
