N2 - Ten carbamate pesticides which exhibit large differences in polarity were determined simultaneously in various environmental samples, using both column liquid chromatography (LC)-thermospray (TSP) mass spectrometry (MS) and LC-ionspray (ISP) MS. For sample clean-up, column chromatography with three stationary phases, neutral aluminium oxide, Florisil and aminopropyl-bonded modified silica, were tested. The aminopropyl stationary phase showed the best results, with acetone-dichloromethane (25:75) as eluent; analyte recoveries were 76-100% for all compounds with a relative standard deviation of 2-8%. In the ISP mass spectra of eight of the ten carbamates, the sodium adduct ion, [M + Na]
