Continuous particles less than 2.5 m in diameter ( PM2.5 ) and carbon monoxide ( CO ) were monitored during 22.9 ppm; SD = 28.1 ppm ) , with a maximum. The highest 3-year average of the 4th maximum concentration for 2015-2017 was 0.070 ppm at South Fayette.

Jun 3, 2020 We measured indoor fine particulate matter (PM2.5) and carbon between PM 2.5 and eCO: among biomass users eCO was 0.20 ppm higher  Dec 27, 2017 In the US, exposure to very fine particulate matter known as PM2.5 is considered safe by the US Environmental Protection Agency's national  micrograms per cubic meter (µg/m3). parts per million (ppm) or parts per billion ( ppb). For particulate matter, sizes are expressed in micron or micrometer  of air pollution and the role of particulate matter in the odor problem are of sulfur dioxide of the order of 2 ppm sulfur dioxide concentrations (up to 2 ppm).

May 22, 2013 A concentration of 400 ppm means that for every million air particles, 400 of them are carbon dioxide molecules (0.04%).

Particulate matter (also known as particle pollution or PM), is a complex mixture of solid particles and liquid droplets in the air. Often characterized according to size, particulate matter is made up of a number of different components, such as:
