This document is a synthesis of the results submitted by the participants during the interlaboratory comparison (ILC) for the analysis of polycyclic aromatic hydrocarbons (PAH) in ambient air organized in 2018 by the LCSQA. This report does not contain any comment or discussion on the submitted data (values higher or lower than a factor of 10 from the participant average results were excluded). It can be subject to modification especially in the calculations of the reference values and z-scores. The data is thus temporary. The final results and discussions will be available in the final version of the report and sent to all participants.
Il s'agit d'un rapport intermédiaire (résultats préliminaires).
