Pm2 5 meaning

PM2.5 is the finer particulate fraction of PM. PM2.5 particles are smaller, and therefore able to be transported further and persist for longer in the atmosphere than PM10. In addition, the smaller the particles, the deeper they can penetrate the respiratory system and the more hazardous they are to breathe. PM2.5 is monitored at fewer sites than PM10. This will change in the Environment PM2.5 abbreviation meaning defined here. What does PM2.5 stand for in Environment?

PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM. Air quality monitors measure concentrations of PM throughout the country.
