PROFICIENCY TESTING SCHEME
Measurement of inorganic gaseous pollutants (SO2, CO, O3, NO and NO2) in filtered ambient air
(21-24 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). From the 21st to the 24th of March 2022, including ERLAP, seven 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]. Two laboratories (A and L) didn’t report values for NO and NO2. Laboratory F didn’t’ report uncertainty values for all zero level of concentrations of each pollutant. The proficiency evaluation, where each participant’s bias was compared to two criteria, 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, two values were found to be questionable (1.1%) and three were unsatisfactory (1.7%) and the rest of the values (97.2%) were satisfactory.
Considering the repeatability and reproducibility evaluation, the results among AQUILA participants at the highest generated concentration levels is satisfactory for measurements of all pollutants beside the SO2 that is affected by the presence of some unsatisfactory values.
