Fine particulate matter measurement and international standardization for air quality and emissions from stationary sources

This paper describes a number of global regulations dealing with very fine ambient particulate matter, PM_2.5 and PM₁₀ and the measurements aspects of PM_2.5 emission measurement methods for stationary sources, particularly of dilution techniques that promote simulation of atmospheric transformation of stack gases allowing for the use of the resulting near-ambient emission data in source apportionment and health risk studies, along with the current progress on international standardization of source PM_2.5 measurement methods.
