A new method used for the extraction of 10 organophosphorous insecticides from water samples coupling single-drop microextraction with gas chromatography–mass spectrometry is presented here. Parameters, such as organic solvent, exposure time, agitation, organic drop volume and salt concentration were controlled and optimised. Overall, extraction was achieved by suspending a 1.5 μl toluene drop to the tip of a microsyringe immersed in a 5 ml donor aqueous solution containing 2.5% NaCl (w/v) and stirred at 800 rpm. The developed protocol was found to yield a linear calibration curve in the concentration range from 0.5 to 100 μg l−1 for all target analytes. Under selected ion monitoring mode, the limits of detection were found to be in the range between 0.010 and 0.073 μg l−1.
