A new study has revealed that ultrafine particulate matter (UFP) can lead to oxidative stress in humans, leading to potential health impacts. UFP are particles smaller than 100 nanometers in size and are typically found in the air from vehicle exhaust, industrial emissions, and other sources. The research team, led by Dr. Mina Bakhtiari, found that exposure to UFP can lead to an increase in the production of free radicals, which can cause oxidative stress. Oxidative stress has been linked to a range of diseases, including cardiovascular and respiratory diseases. The team hopes that their findings will help to inform public health policies to reduce exposure to UFP.
