mass median aerodynamic diameter.
Particles of 0.3 15 μm aerodynamic diameter were used.
The stage at the median amount of radioactivity defined the mass median aerodynamic diameter (MMAD).
Particulate matter (PM) is categorized by aerodynamic diameter into three classes: coarse PM 2.5 10 μm in aerodynamic diameter (PM10), fine PM 0.1 2.5 μm in aerodynamic diameter (PM2.5), and ultrafine PM < 0.1 μm in aerodynamic diameter.
PM2.5: particulate matter (PM) with an aerodynamic diameter <2.5 μm.
UFP: ultrafine particles, particles with an aerodynamic diameter <0.1 μm.
The APS measured the aerodynamic diameter distribution of the aerosols.
Different particle size ranges including ultrafine particles (with aerodynamic diameter < 0.1 μm), fine particles (with aerodynamic diameter < 2.5 μm), and coarse particles (with aerodynamic diameter 2.5 10 μm) are of importance to this framework.
Fine particles, PM2.5, are particles having an aerodynamic diameter of < 2.5 μm, and ultrafine particles, PM0.1, have an aerodynamic diameter of < 0.1 μm.
We used PM data for PM with aerodynamic diameter ≤10 μm (PM10) and aerodynamic diameter ≤ 2.5 μm (PM2.5) from the U.S. Environmental Protection Agency for the year 2000.
PM2.5, particulate matter with aerodynamic diameter ≤ 2.5 μm; PM10, particulate matter with aerodynamic diameter ≤10 μm; PAH, polycyclic aromatic hydrocarbon; O3, ozone.
