Generation and Behavior of Airborne Particles (Aerosols)
www.cdc.gov• Particle-particle interaction small • Particle-surface interaction large • Particle charge depends mostly on generation process, surface energy, humidity, time in the air • Airborne particle charge gradually decreases due to ions in air (particles are nearly neutral after about 30 min)
