Ultrafine Particulate Matter (UFP)

Ultrafine Particulate Matter (UFP) refers to tiny particles less than 0.1 micrometers in diameter, much smaller than a human hair. These particles are emitted from sources like vehicle exhaust, industrial processes, and combustion of fuels. Due to their small size, UFP can penetrate deep into the lungs and enter the bloodstream, potentially affecting respiratory and cardiovascular health. Because they are invisible and diffuse easily in the air, UFP pose unique challenges for detection and regulation. Their presence underscores the importance of monitoring air quality and reducing emissions to protect public health.
