Headspace solid-phase microextraction for the determination of volatile sulfur compounds in odorous hyper-eutrophic freshwater lakes using gas chromatography with flame photometric detection

► Optimized HS-SPME by GC-FPD for routine determination of fives VSCs in lake waters. ► VOSCs and the inorganic species H2S were simultaneously determined. ► Parameters that may affect to the determination were systematically optimized. ► The detection of VSCs was linear over three orders of magnitude for target compounds. ► The method was applied to analysis of odorous water samples from the Lake Taihu.
