Overzicht van onderzoek naar automatische meetmethoden voor het vaststellen van fijn stof

This report describes studies on current techniques for determining the concentration of the fine fraction (PM2.5) of particulate matter in the troposphere. The performance of the sampling technology for PM2.5 was investigated by means of a literature study based on a selection of publications (after 2000) comparing the automatic sampler method with the reference method. It was the express wish of the concerned authorities to investigate the performance of the PM2.5 methods and to harmonize measurement methodology. A careful selection of PM2.5-samplers is important if the PM2,5 methodology is to be improved. This meant considering at least the method's principle, the range of application, the effect of different configurations, effects of varied ambient conditions and uncertainties. The study's purpose was to facilitate the assessment of both the PM2.5 measurement method performance and the process of harmonization and/or normalization.
