Abstract
The research and development trend, and recent activities in international standardization, of characterization and analysis method for emission behavior of PM10/PM2.5 and nanometer scaled particles from stationary sources such as factory, power plants and waste incinerators was introduced. The international standard method for PM10/PM2.5 emission behavior from stationary sources is discussed in ISO TC146/SC1/WG20. In this committee, three kinds of PM10/PM2.5 separation methods from flue gas are focused upon, and the ISO committee draft, Part 1 “Cascade impactors”, has already been proposed. The subjects and our improved proposal of this draft, and the structure and performance of virtual impactor, which is under discussion as Part 3 of this ISO, were introduced. Furthermore, attention has to be paid to condensable suspended particulate matter (SPM), which may pass through the high-performance dust collectors, because it is a new high risk matter for human health in the future. Condensable SPM is collected by the mass concentration measurement with a dilution method, which is discussed in ISO TC146/SC1/WG21. However, there are many issues that must be solved for successful development of measurement methods of such nanometer scaled particles and the optimal dilutor design.
