Abstract Due to increasing use of polar pesticides, they are found together with their degradation products in ground- and surface waters serving for drinking water treatment. The triazine derivatives acetamido-atrazine, ametryne, atrazine, cyanazine, deethylatrazine, deethyldeisopropyl-hydroxyatrazine, deethyl-hydroxyatrazine, deisopropyl-atrazin, deisopropyl-hydroxyatrazine, desmetryn, hydroxyatrazine, prometryne, propazine, simazine, terbumeton, terbutryne and terbutylazine, and the pesticides 2,4-D, dichlorprop, isoproturon, diuron, metolachlor, glyphosate, metsulfuronmethyl and dalapon, all of them belonging to this type of pesticides, have been studied. For determination of triazine derivatives UV detection by means of diode array detector (DAD) as well as mass spectrometric (MS) detection coupled by thermospray interface (TSP) have been used successfully after liquid chromatoraphic (LC) separation. Interfaces like thermospray (TSP), electrospray (ESP) and atmospheric pressure chemical ionisation (APCI) were examined with regard to their suitability for substance-specific detection of polar pesticides by flow injection analysis (FIA) with MS- and tandem mass spectroscopic detection (MS/MS) without preceding LC separation. Optimised detection conditions for these pesticides using FIA are presented, and solutions for occurring problems are offered.
