What's the difference between PM10 and PM2.5?

The difference between PM10 and PM2.5 is size. PM refers to particulate matterparticles in the air. Those particles are things like organic dust, airborne bacteria, construction dust, and coal particles from power plants (heres what researchers in Shanghai found when they collected air pollution particles and found out what they were made of).Using Indoor Positioning and Mobile Sensing for Spatial slub pm2.5This pilot study investigated the potential of a mobile monitoring method to map highly variable PM2.5 distributions inside an occupied one-bedroom apartment, coupling a new ultrasound localization method with a pair of collocated research-grade and low-cost sensors (SidePak and PTQS).The impact of PM2.5 on the human respiratory systemPM2.5 (particles less than 2.5 micrometers in diameter) can penetrate deeply into the lung, irritate and corrode the alveolar wall, and consequently impair lung function. Hence it is important to investigate the impact of PM2.5 on the respiratory system and then to help
