Comparative field test for measurement of PM_(10) dust in atmospheric air using gravimetric (reference) method and β-absorption method (Eberline FH 62-1)

摘要

The paper presents the results of a field test carried out in Gdansk region between 01-01-2010 and 31-12-2010 in order to demonstrate equivalence of the Eberline FH 62-1 sampler to the reference gravimetric method of suspended PM_(10) dust measurement. The differences in PM_(10) dust concentration provided by both methods have been discussed for different seasons of the year. A method of estimation of the correction factors/correction equations has been described based on the European Union guide "Demonstration of Equivalence of Ambient Air Monitoring Methods. EC Working Group on Guidance for the Demonstration of Equivalence". The results obtained from Eberline sampler are equivalent to the ones from gravimetric method, but after application of data correction. The investigation revealed different correction factors/correction equations for winter and summer season. The winter season is characterized by higher PM_(10) concentration and bigger discrepancies between both methods. A lack of equivalence has been found for PM_(10) dust concentration higher than 30 μg m~(-3).
