Equivalence of PM10 instruments at a road traffic site: a study in Stockholm spring 2012

According to the EU-directive directive 2008/50/EC on ambient air quality and cleaner air for Europe, the assessment of the levels of PM10 in areas where PM10 is above the upper assessment level shall be made by fixed measurements with the reference method given in the directive or any method that has been shown to be equivalent with the reference method. The reference method is described in the document EN 12341. The equivalence of a measurement method shall be tested according to procedures given in a guidance document published within EU. All decisions about equivalence of a method are made in each member state by the national competent authority. The Swedish EPA is the competent authority in Sweden and declares equivalence based on recommendations from the National Air Quality Reference Laboratory (NAQRL). All declarations of equivalence of instruments for measuring PM10 in Sweden have been based on studies made in other European counties, mainly in Central Europe. The declarations can be regarded as provisional as they not are based on tests at the specific conditions that can occur in Sweden. Thus all declarations need to be supplemented by further testing in Sweden. NAQRL judged that the results from the Central European tests in the urban background and at rural sites is representative also for Swedish conditions. However, most exceedances of the PM10 EU daily limit values in Sweden occur at busy roads during spring, when the PM10-fraction is dominated by coarse particles originating from abrasion of roads by studded tyres. These conditions are specific for Sweden (and other Nordic countries) and are not included in the Central European tests. Thus a supplementary equivalence study was performed at a busy street in Stockholm during spring 2012. The result from this equivalence study was combined with the results from the previous European tests to assess the equivalence of a measurement method.
