A powerful tool for the wide-screening of organic contaminants in citizen science initiatives: Development and validation of a SBSE GC-QToF-HRMS method
In the framework of “The Gems of Water” citizens’ engagement activities, a new methodological approach was studied. The report presents the development and optimisation of a method for wide-screening of organic apolar pesticides in surface waters using Stir Bar Sorptive Extraction (SBSE) coupled with Gas Chromatography-Quadruple Time of Flight-High Resolution Mass Spectrometry (GC-QToF-HRMS). The report describes the optimisation of water extraction and instrumental parameters for around 200 pesticides. Calibration curves, limits of detection, and limits of quantification were determined. The method was optimized through reproducibility and recovery tests, as well as isochronous stability testing. Different passive and active extraction modalities were investigated. Based on the obtained results, most suitable parameters among those tested were selected to improve the methodology employed for measuring of pesticides in water samples. The report concludes that the method developed herewith has the potential to be applied in citizen science initiatives for water quality monitoring.
