Airborne Nanoparticles

Airborne nanoparticles are tiny particles, smaller than a micrometer, suspended in the air. Due to their small size, they can easily penetrate deep into the lungs when inhaled, potentially causing health issues. They originate from various sources such as vehicle emissions, industrial processes, combustion, and natural events like wildfires. Because of their high surface area relative to size, they can carry toxic substances and penetrate biological barriers more readily than larger particles. Monitoring and controlling airborne nanoparticles is important to reduce health risks and protect environmental quality.
