Abstract
Physical properties and chemical composition of atmospheric aerosols are of extreme importance, in many fields of interest, namely the Environment even with legal implications. Atmospheric sampling poses inherent problems with consequent demands on sampling optimisation, with sampling strategies requiring validation. In this work a study was conducted aiming at validating the collection of atmospheric aerosols in equivalent fractions. Aerosols were actively collected using a sampling system consisting of a PM10 (≤ 10 μm) inlet coupled to a manifold with six channels of filter holders. The set up was mounted on the roof of building C8 of FCUL, in Lisbon. Samples were treated and analysed by Ion Chromatography (IC) for chloride, nitrate and sulphate anions, in the aerosol water-soluble fraction. The evaluation of the compatibility of measurement results was used to validate sampling and analytical procedures. The results obtained for the measurements in the six filter holder positions are, in general, compatible and the positions can be considered metrologically equivalent.
