Nanoparticle Journeys: Air to Surface
Tiny Travelers: Exploring the Journey of Airborne Nanoparticles Our world is filled with microscopic particles, some harmless, others potentially harmful. Among these are nanoparticles – tiny specks with a diameter less than 100 nanometers – that can travel vast distances through the air. Understanding how these airborne nanoparticles transport and deposit themselves is crucial for tackling environmental and health concerns. The Journey Begins: Nanoparticles enter the atmosphere from various sources, both natural and anthropogenic. Volcanic eruptions spew ash containing fine particles, while wildfires release smoke laden with soot and other pollutants. Industrial processes, vehicle emissions, and even everyday activities like cooking can contribute to nanoparticle levels in the air. Wind as the Conductor: Once airborne, these nanoparticles become part of...
