eng	Environmental monitoring of fungicide dichlofluanid using boron-doped diamond electrochemical sensor.	In this study, we analyzed dichlofluanid (DFA). There are not any previous studies on electrochemical determination of DFA. From cyclic voltammograms we observed that this pesticide provides two oxidation peaks at the potential values of +1.28 V and +1.76 V. Current response on BDDE showed good stability in wide pH range. Britton-Robinson buffer of pH 6 was chosen as a suitable supporting electrolyte for DFA determination. From the calibration curves obtained under the optimized conditions of differential pulse voltammetry we achieved very good sensitivity (LOD 0.33 µM) with wide linear dynamic range (LDR = 1-50 µM). This method was applied in analysis of spiked samples of river water with very good recovery (98.5-101.7%).	Boron doped diamond electrode; Dichlofluanid; Voltammetry; Electroanalysis.
