Hollow fibre-based liquid-phase microextraction technique combined with gas chromatography-mass spectrometry for the determination of pyrethroid insecticides in water samples

► Simultaneous analysis of nine pyrethoids by HF-LPME-GC/MS in water samples. ► Analysis of spiked real water samples showed acceptable results. ► Environmentally friendly technique. ► Methodology allows the simultaneous analysis of several samples. ► HF-LPME-GC/MS method is a valuable tool for monitoring pyrethroids in water samples.
