Abstract: Within the harmonisation programme of Air Quality monitoring in Europe the European Reference Laboratory of Air Pollution (ERLAP) is organizing Inter-Laboratory Comparison Exercises (ILC). From the 26th to the 29th of June 2017, eight 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 and its recent amendments 2015/1480/EC. 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. On the basis of adopted criteria, 78.1% of the results reported by AQUILA laboratories were good both in terms of measured values and reported uncertainties. The rest of the results had good measured values, but the reported uncertainties were either too high (11.5%) or too small (6.5%). Only five values (1.9%) were found questionable and 1.9% unsatisfactory. Comparability of results among AQUILA participants at the highest generated concentration levels is satisfactory only for the measurements of some pollutants. The performance of SO2 and NO2 are above the limits respectively from 15 and 50 nmol/mol.
