In this study, we measured the concentration of particulate matter (PM) and ammonia (NH₃) emission in the winters according to the breeding type of laying hen houses. Measurements were performed thrice in Barn, Aviary, and Cage houses every 2 weeks from December to January. The changes in the PM₁₀ and PM_2.5 concentrations were similar in all three breeding

What Is Particulate Matter (PM)? One of six criteria air pollutants, as defined by the EPA, particulate matter is an amalgamation of solid and liquid particles suspended in the air. Most particulate matter (abbreviated ‘PM’) is microscopic and inhalable.

Some of these are large enough to see, like smoke, smog, or soot, but the most harmful are smaller, invisible particles 6 . What is the abbreviation for Primary Particulate Matter? What does PPM stand for? PPM abbreviation stands for Primary Particulate Matter.

The diesel fuel used in Sweden is low in sulphur content (< 10 ppm) and therefore the diesel vehicles passing the site contribute less to particle emissions in

Indoor pollution sources that release gases or particles into the air are the primary in some humans exposed at elevated levels (above 0.1 parts per million). May 22, 2013 A concentration of 400 ppm means that for every million air particles, 400 of them are carbon dioxide molecules (0.04%). We wanted to know total surface area of all the particles in the liquid.
