DIN EN 16339:2013-11 EN 16339:2013 (E) 4 Introduction Experience gained across the European Union (EU) in imp
23、lementing EU ambient air quality legislation 1 has shown that, generally, for nitrogen dioxide (NO2), meeting the annual average limit value of 40 g/m3is more problematic than meeting the 1-h limit value of 200 g/m 2. EU Directive 2008/50/EC 1 stipulates that European Union Member States shall apply
24、 the reference measurement methods and criteria specified in the Directive. For NO2monitoring in ambient air, the reference method being that described in EN 14211:2012 3. However, a Member State may use any other method that provides results equivalent to that of the reference method, to be demonst
25、rated in accordance with the Guide for the demonstration of equivalence of ambient air monitoring methods 4. The GDE devotes specific paragraphs to methods based on diffusive sampling. For the measurement of longer-term average concentrations of nitrogen dioxide for comparison with the annual averag
26、e limit value diffusive sampling is an attractive alternative to fixed monitoring using the reference methodology described in EN 14211 because of small size of diffusive samplers; no requirement for electric power; potential for covering areas with a high spatial density; cost effectiveness. Conseq
27、uently, diffusive samplers can partially substitute and supplement fixed monitoring as an instrument for the assessment of air quality, provided that they fulfil the specific Data Quality Objectives given in 1. At the time of publication of this standard, no full demonstration of equivalence accordi
28、ng to 4 has been performed. However, some studies have compared NO2annual average concentrations measured by chemiluminescence and by diffusive samplers 5, 6, 7 and 8. These have shown the potential of diffusive sampling to meet the data quality objective of 15 % expanded uncertainty for fixed measu
29、rements 1. The methodology described in this standard can be applied to obtain air quality information with a relatively high spatial density that can be used to complement the appropriate siting of fixed monitoring stations, or in the validation of dispersion models. Further, the methodology descri
30、bed can be used for simultaneously measuring sulphur dioxide (SO2) when using ion chromatography as the method of analysis. The analytical method is described in 9, 10 and 11. This standard has been prepared based on the findings of reviews of implemented diffusive samplers in the European Union 12.
31、 The methodology described in this standard may also be used to determine NO2in indoor air. Appropriate strategies for NO2measurement in indoor air are described in EN ISO 16000-15. DIN EN 16339:2013-11 EN 16339:2013 (E) 5 1 Scope This European Standard specifies a method for the sampling and analys
32、is of NO2in ambient air using diffusive sampling followed by extraction and analysis by colorimetry or ion chromatography (IC). It can be used for the NO2measurement in a concentration range of approximately 3 g/m to 130 g/m3. A sample is typically collected for a period of 1 to 4 weeks 13, with exp
33、osure periods depending on the design of the samplers and the concentration levels of NO2. Several sorbents can be used for trapping NO2in ambient air using a diffusive sampler. This standard specifies the application of triethanolamine as the reagent. Nitrous acid and peroxyacetyl nitrate are the m
34、ajor chemical interferences of sorption by triethanolamine. However, in ambient air monitoring over long sampling times, both contaminants are generally present at low concentrations relative to NO2. Moreover, these species can also interfere with the measurement of NO2when applying the EU reference
35、 method for NO2monitoring based on chemiluminescence (see 2). This standard describes the application of a tube-type sampler with either a cylindrical or a slightly conical tube. Its typical uptake rate is about 1 cm3/min. Only for this sampler type sufficient evidence of validation has been found i
36、n a literature survey 12. The relative expanded uncertainty of NO2measurements performed using these tube-type diffusive samplers can potentially be lower than 25 % for individual measurements. When aggregating results to form annual average values, the relative expanded uncertainty can be further r
37、educed to levels below 15 % due to the reduction of random effects on uncertainty 6. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for the application of this document.
