The aim of t
43、his European Standard is to present guidance on the measurement procedures to be followed when monitoring elemental carbon (EC) and organic carbon (OC) collected on filters, following Council Directive 2008/50/EC on ambient air quality and cleaner air for Europe 1. This requires the chemical speciat
44、ion of the sub-2,5 m size fraction of suspended particulate matter (PM2,5) in ambient air, as described in Annex IV. The method set out in this European Standard provides operational definitions of the measured quantities. Currently no traceable primary reference materials are available for EC and O
45、C analysis and no absolute scientific distinction between EC and OC is possible. BS EN 16909:2017g8g17g3g883g888g891g882g891g483g884g882g883g889g3g525g8g5266BS EN 16909:2017EN 16909:2017 (E) 7 1 Scope This European Standard is applicable for the measurement of elemental carbon (EC) and organic carbo
46、n (OC) following the requirement for all EU member states to measure EC and OC in particulate matter from June 2010 at background sites according to the Council Directive 2008/50/EC on ambient air quality and cleaner air for Europe 1. This European Standard describes the analytical procedures for de
47、termining EC and OC on quartz fibre g136g139g142g150g135g148g149g3g131g149g3g586g137g512g133g1432, and the subsequent calculation of concentrations as g/m3. Sampling onto filters is to be done in accordance with EN 12341:2014 for PM2,5. The sampling process determines the size fraction of the partic
48、ulate matter, the retention of semi-volatile material, and uptake/loss of volatile organic compounds on the filter at the time of sampling. The same analysis method may also be used for smaller size fractions than PM2,5. Any possible additional artefacts for larger particles, e.g. pyrolysis or highe
49、r concentrations of carbonates, should be assessed. The scope includes rural background and urban background sites. The measurement method can also be applied to other site types, provided that the measurement range given below is not exceeded. The use of this standard at all site types allows the assessment of additional exposure of people in urban areas as stated in the objectives of the council directive and to achieve coherence in the European approach. The applicable concentration range of the proposed method is limited by the optical correction and instrument applied i
