Measurement of Elemental and Organic Carbon in Europe

The new Air Quality Directive 2008/50/EC is asking in Annex IX that elemental (EC) and organic (OC) carbon as well as soluble ions should be measured at selected background sites in each Member State. Several methods (thermal, optical or photo-acoustic methods) to determine elemental and organic carbon exist which do not always deliver comparable results. European experts in EC/OC measurements met at the JRC in Ispra on 10th and 11th February 2009 to discuss during a workshop the best suitable European method. The main tasks of this workshop were - to discuss the advantages and disadvantages of different methods for the determination of OC and EC, - to get information from the Member States on existing methods or even standards being applied, - to initiate discussions on a preferred basic method to be standardised by CEN within the scope of Directive 2008/50/EC. The conclusions of this workshop will directly feed into CEN and the corresponding Working Group to clearly define their task for European wide standardisation and hence harmonisation.
