Validation of a method for the analysis of 77 priority persistent organic pollutants in river water by stir bar sorptive extraction in compliance with the European Water Framework Directive

► Multi-residue method to identify and quantify semi-volatile organic compounds in river waters. ► Banned compounds by the European Water Framework Directive (PCBs, OCPs, PAHs, PBDE, pesticides). ► Only one extraction step for 77 compounds, previous to SBSE-GC-MS/MS analysis. ► LOQs and LODs lower than previous presented method for priority pollutants analysis. ► Validation of the method (quality parameters, accuracy, proficiency testing assays).
