Procedures for the determination of polar pesticides in surface and ground water after their preconcentration by dispersive liquid-liquid microextraction and solid-phase extraction on Oasis® HLB (3 cc/60 mg) extraction cartridges are proposed. Conditions for the separation and determination of pesticides from the following classes by micellar electrokinetic chromatography were chosen: arylhydroxycarboxylic acids; sym-triazines; triazinones; urea derivatives; neonicotinoids; carbamates; triazoles; imidazoles; benzimidazoles; and organophosphorus compounds. The determination limits of pesticides in water were 0.5-20 μg/L with consideration for preconcentration. The relative standard deviation of the results of analysis was no higher than 10%. © Pleiades Publishing; Ltd; 2013;
