PROFICIENCY TESTING SCHEME
Measurement of inorganic gaseous pollutants (SO2, CO, O3, NO and NO2) in filtered ambient air
(28-31 March 2022, Ispra-Italy)
European Commission harmonisation programme for air quality measurements
Within the harmonisation programme of Air Quality monitoring in Europe the European Reference Laboratory of Air Pollution (ERLAP) organises Proficiency Tests (PT).
During the period 28 - 31 of March 2022, including ERLAP, ten Laboratories of AQUILA (Network of European Air Quality Reference Laboratories) met for a laboratory comparison exercise in Ispra (IT) to evaluate their proficiency in the analysis of inorganic gaseous air pollutants (NO, NO2, SO2, CO and O3) covered by the European Air Quality Directive 2008/50 EC [1] and its last amendments 2015/1480/EC [42].
One laboratory (H) didn’t report values for NO2 and some values of NO, due to technical issues with the analytical instrumentation.
The proficiency evaluation, where each participant’s bias was compared to two criteria (z/z’-score and En-score), provides information on the current situation and capabilities to the European Commission and can be used by participants in their quality control system.
Based only on the z/z’-score evaluation, between all the results reported, 99.3% were satisfactory and only two values were found to be questionable (0.7%) and none were unsatisfactory.
Considering the repeatability and reproducibility evaluation, the results among AQUILA participants at the highest generated concentration levels are satisfactory for measurements of all pollutants.
