Multi-residue method for the determination of 16 recently used pesticides from various chemical groups in aqueous samples by using DI-SPME coupled with GC-MS

► In this study DI-SPME-GC-MS methodology was developed. ► The 100 μm of PDMS and 85 μm of PA fibers were applied and compared. ► Sixteen recently used pesticides from various chemical groups were determined. ► Method was validated and applied to the analysis of water samples. ► Methodology is a valuable tool for monitoring selected pesticides in water samples.
