The aim of investigation was to elaborate an analytical method for determination of bentazone in soil, plant and water samples. The analytical procedure consists of three elementary processes: extraction and reextraction of analyzed substance from matrix, cleaning of extract using SPE (Solid Phase Extraction) column with Florisil active solid and final determination using gas chromatography with ECD and MS detection. The detection limit (LOD) of bentazone was 0.0002 mg/kg (for soil and plant samples) and 0.00005 mg/kg for water samples. The range of fortified recoveries of the method was 92–98%.
