EN 16913:2017 (E) 5 Introduction This European Standard describes how to measure a specified range of anions and cations in PM2,5as deposited on filters. The EU Air Quality Directive 2008/50/EC 1 on
37、ambient air quality and cleaner air for Europe requests the measurements of concentrations of NO3-, SO42-, Cl-, NH4+,Na+, K+, Mg2+, Ca2+in PM2,5at rural background locations. In Annex IV of the Directive, guidance for these measurements is given. Measurements of anions and cations in PM are being pe
38、rformed by the EMEP programme, mainly by using a filterpack with limited particle size selectivity. The cooperative programme for monitoring and evaluation of long-range transmission of air pollutants in Europe (EMEP) was launched in 1977 as a response to the growing concern over the effects on the
39、environment caused by acid deposition. EMEP was organized under the auspices of the United Nations Economic Commission for Europe (UNECE). Today EMEP is an integral component of the cooperation under the Convention on Long-range Transboundary Air Pollution. Directive 2008/50/EC requires that measure
40、ments at rural sites, where appropriate, are coordinated with the monitoring strategy and measurement programme of EMEP. Although, there are different sampling procedures involved, a common approach is used for the analytical procedure. In order to keep the agreement between existing EMEP data and d
41、ata to be produced using this European Standard as close as possible, the EMEP protocol has been taken as starting point for this European Standard. This European Standard differs from the EMEP protocol in the sense that measurement of anions and cations are done in PM2,5, and that a number of criti
42、cal parameters (e.g. choice of filter material) are fixed. Additional attention is given to harmonizing these critical parameters with elemental carbon/organic carbon (EC/OC) measurements and with PM2,5measurements as well, as sampling is usually done simultaneously. BS EN 16913:2017EN 16913:2017 (E
43、) 6 1 Scope This European Standard specifies a method for the determination of the mass concentration of water soluble NO3-(nitrate), SO42-(sulphate), Cl-(chloride), NH4+(ammonium), Na+(sodium), K+(potassium), Mg2+(magnesium), Ca2+(calcium) in PM2,5as deposited on filters. This European Standard des
44、cribes the analytical procedures for determining anions and cations as part of the PM2,5particulate phase, sample extraction and analysis of anions and cations by ion chromatography. Sampling onto filters will be done in accordance with EN 12341 for PM2,5. NOTE 1 Alternatively, cations, excluding am
45、monium, can be analysed by inductively coupled plasma optical emission spectrometry (ICP-OES). Ammonium can also be analysed by photometry or conductometry. This European Standard can be used for the measurements of anions and cations as required by Directive 2008/50/EC. The method does not take int
46、o account the possible losses during sampling due to evaporation. NOTE 2 NO3-, Cl-, NH4+are part of the volatile fraction of PM2,5, and the concentrations determined using this standard can be used as minimum values for the concentrations of these ions in PM2,5. NO3-, NH4+, Cl-are usually up to 30 %
47、 underestimated due to evaporational losses from the filter during sampling. This European Standard may be used at rural and urban background sites and road sites that are in accordance with the siting criteria of Directive 2008/50/EC. This European Standard is applicable to the measurement of anion
48、/cations in PM2,5samples corresponding to PM2,5mass concentrations between approximately 1 g/m3(i.e. the limit of detection of the standard measurement method (EN 12341) expressed as its uncertainty) up to 120 g/m3. The validated range of the anion and cation concentrations based on the field valida
49、tion measurements is presented in Table 1.
