Analyses were performed by reverse phase (RP) HPLC with direct fluorescence detection with mobile phase methanol:water, 40:60 (v/v) with 0.6% (v/v) ammonia. The extraction of analytes from water samples was performed with the use of micellar systems. Specifically, oligoethylene glycol monoalkyl ether (Genapol X-080) and polyoxyethylene 10 lauryl ether (POLE) were used as extractants. The recoveries of fungicides obtained in spiked water samples ranged from 68% to 94% for Genapol and from 68% to 96% for POLE. The limit of detection (LOD) was lower than 6 μg L−1 for carbendazim, 7 μg L−1 benomyl, 0.15 μg L−1 for thiabendazole and 0.01 μg L−1 for fuberidazole in both surfactants.||URI:||http://hdl.handle.net/10553/47167||ISSN:||0009-5893||DOI:||10.1365/s10337-004-0364-z||Source:||Chromatographia [ISSN 0009-5893], v. 60, p. 151-156|
