"Fine" particulate matter, as 2.5 PM is referred to by health agencies, means something particularly dangerous to sensitive groups that demands protection. The particulates, and whatever toxins they may be carrying with them, can’t just penetrate your lungs. They can also pass into your bloodstream.

Particulate matter (PM) in the atmospheric air or in any other gas cannot be expressed in terms of ppmv, ppbv, volume percent or mole percent. PM is most usually (but not always) expressed as mg/m 3 of air or other gas at a specified temperature and pressure.

Ppm particulate matter

Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope. Particulate matter (PM) is one of the air pollutants regulated by the National Ambient Air Quality Standards (NAAQS). Reducing emissions of inhalable particles improves public health as well as visibility. Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.

PM2.5 and PM10 = particulate matter less than 2.5 microns and 10 microns, respectively; ppm = parts per million; μg/m3 = micrograms per cubic metre. Apr 29, 2020 Currently, only pollution thresholds for particulate matter (PM10 and PM2.5) concentrations differ between the 1-hour and the 24-hour time scale. Jul 7, 2016 To better characterize the indoor concentrations of particulate matter 3,469 ( 3,350–3,588) μg/m3 for PM2.5 and 21.8 (21.1–22.6) ppm for CO. Aug 18, 2012 PM2.5 concentration between 2.5 and 8.8 fold. At the seven measurement points, daily concentrations ranged from 576.7 to 623.4 ppm for CO2 Jul 6, 2017 Intake fractions from residential and occupational indoor sources range from 470 ppm to 62 000 ppm, mainly as a function of air exchange rate Apr 22, 2019 The pollutant in question is particulate matter (PM), tiny particles or a reduction in lung function in subjects exposed to 0.080 ppm of ozone. Aug 22, 2003 In the meantime, a less healthful standard of 0.12 ppm (120 ppb) for one lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile Apr 26, 2019 The difference between PM10 and PM2.5 is size. “PM” refers to particulate matter —particles in the air. The “10” and the “2.5” refer to microns.

Even though much particulate matter is so small as to be invisible to the naked eye, it is possible to see others in high concentrations like smoke from a chimney, a candle, or cigarette.
