Recently, more attention has been paid to other particle sizes, as well, including PM0.3 and PM.01. They use two main categories to do this: PM10 and PM2.5. What Are the Particulate Matter Categories?Īs mentioned, scientists typically classify airborne particles by size. And as we've seen during the novel coronavirus pandemic, short- and long-term exposure to airborne particles can lead to negative or even serious health effects, even if these particles can't be seen by the naked eye. Even natural sources, such as wildfires, wood burning stoves, pollinating plants, and unpaved dirt roads, can emit particulate matter into indoor or outdoor air.Įxamples of PM include dust, smoke, soot, pollen, mold spores, vehicle exhaust, dirt, and yes-bacteria and viruses. Particulate matter comes not only from industrial sources like factories, construction sites, mines, and power plants, but also vehicle emissions and additional fuel-burning activities. Particulate matter (PM) is a broad term used to refer to airborne pollutants or contaminants-those small bits of solids or liquid droplets that circulate throughout the air.
A Quick Primer on Particulate Matter, Air Pollution, and Human Health Keep reading to learn more about PM0.3 and coronavirus and discover the cost-effective strategies you can employ at your organization to keep your workforce safer. This has led many people to wonder: what is PM0.3 and why is it so important? One particle size, PM0.3, has recently become a source of greater discussion during the global COVID-19 pandemic. Scientists classify these airborne particles by diameter size in units called microns (micrometers).
