Challenges in the Preparation of Water Matrix Reference Materials for PAHs and Pesticides: Examples from the SWIFT-WFD Proficiency Testing Schemes

In accordance with the Article 8 of the Water Framework directive (WFD), EU Member States are required to establish monitoring programmes of the surface and groundwater quality within each river basin district. As such data are the basis for regulatory decisions and measures required to achieve WFD environmental objectives, appropriate analytical quality assurance/quality control (QA/QC) tools have to be implemented by the monitoring laboratories. In this respect, Reference Materials (RMs) play an unquestionable key role. Within the framework of SWIFT-WFD project, several approaches for the preparation of matrix RMs for the analysis of polycyclic aromatic hydrocarbons (PAHs) and pesticides in water have been exploited and used in wide-scale Proficiency Testing (PT) schemes. The different strategies employed in the preparation of water matrix RMs for organic analytes are hereby presented and described. Through the review of PT scheme results, some reflections about the applicability and suitability of the different approaches are presented.
