particulate matter having aerodynamic diameters less than or equal to 10 microns
Particles less than 1 millionth of a metre in size
Particulate matter of mass median aerodynamic diameter (MMAD) less than or equal to 10 micrometers.
particulate matter 10 micrometers or smaller in diameter
Particulate matter at or below 10 microns in aerodynamic equivalent diameter
Fine particulates (airborne particles)
Particles with a maximum diameter of 10 µm.
Particulate Matter (smaller than 10 microns)
The U.S. EPA defines PM10 as particulate matter with a diameter of 10 micrometers collected with 50% efficiency by a PM10 sampling collection device. However, for convenience in this reference material, the term PM10 includes all particles having an aerodynamic diameter of less than or equal to 10 micrometers.
Common global sampling convention that quantifies the mass of particulate air pollution in the environment. The PM 10 convention collect particles in the ulrafine range. Most PM 10 is derived from combustion sources.
Particles smaller than 10 micrometers.
A criteria air pollutant consisting of small particles less than 1/7 the width of a single human hair. Their small size allows them to make their way to the air sacs deep within the lungs where they cause harmful health effects. PM10 also causes visibility reduction.
particulates of diameter range 2.5 to 10 microns, a measure of particulate atmospheric contamination
fine particulate matter suspended in the atmosphere. PM10 particles have a diameter of less than 10 micrometers.
Particulate matter greater than 10 microns in size
A USEPA standard that includes additional controls on particulates sized 10 micron and smaller
Fine dust and particles where the particles are less than 10 micrometers in diameter.
Particulate matter less than 10 µm aerodynamic diameter
Particulates which are less than 10 .m across. These can penetrate deep into the lungs, aggravating Asthma and other respiratory problems. The EPAQS standard for particulates is 50 g/m3, averaged over a 24h period.
Particulate Matter Less Than 10 Microns in Diameter
a criteria air pollutant that is particulate matter in ambient air exceeding 10 microns in diameter.
Fine Particulate Measures
Airborne suspended particles with an aerodynamic diameter of 10 microns or less.
particles less than 10 micrometer in diameter, small enough to be inhaled but do not reach the lungs.
tiny solid or liquid particles of soot, dust, smoke, fumes, and aerosols. The size of the particles (10 microns or smaller, about 0.0004 inches or less) allows them to easily enter the air sacs in the lungs where they may be deposited, resulting in adverse health effects. PM10 also causes visibility reduction and is a criteria air pollutant
An air pollutant consisting of small particles with an aerodynamic diameter less than or equal to a nominal 10 microns (about 1/7 the diameter of a single human hair). Their small size allows them to be inhaled but they do not reach the lungs.
A newer standard for measuring the amount of solid or liquid matter suspended in the atmosphere (“particulate matterâ€). Refers to the amount of particulate matter under 10 micrometers in diameter. The smaller PM10 particles penetrate to the deeper portions of the lungs, affecting sensitive population groups such as children and people with respiratory diseases.
