“…Azoxystrobin was eluted from the SPS cartridge using 5 ml of dichloromethane and ethyl acetate (70:30 v/v). The elute was evaporated to near dryness and quantified with 1 ml of acetonitrile, and aliquot (10 ll) was injected into the HPLC (Sundravadana et al 2008).…”

Azoxystrobin is a broad-spectrum, systemic and soil-applied fungicide used for crop protection on more than 80 different crops. Azoxystrobin use has induced water pollution and ecotoxicological effects upon aquatic organisms, as well as heath issues. Such issues may be solved by phytoremediation. Here, we tested Plantago major L., Helianthus annus L. and Glycine max L. to clean soils under laboratory conditions. Results show that the accumulation efficiency of azoxystrobin and azoxystrobin acid in roots was higher than those of leaves. G. max roots were an efficient accumulator of azoxystrobin (25.32 mg/ kg), followed by P. major roots (20.62 mg/kg) and H. annus roots (18.29 mg/kg), within 10 days, respectively. In the leaves, azoxystrobin significantly translocated into the P. major leaves and reached the maximum after 10 days of exposure (15.03 mg/kg), followed by H. annus leaves (9.8 mg/kg), while it reached the maximum after 3 days of exposure (3.12 mg/kg) in G. max leaves. Azoxystrobin acid significantly accumulated in P. major roots more than the G. max and H. annus roots. In the leaves, azoxystrobin acid significantly accumulated in G. max more than P. major and H. annus. The presence of P. major with Tween 80 had effects on azoxystrobin desorption from soil, plant uptake metabolism and translocation more than P. major alone.

“…Usually, it is necessary to apply some separation 2 procedure before the analysis, most often it is liquid/liquid or liquid/solid 3 phase extraction. High performance liquid chromatography (HPLC) was 4 used for AS determination in combination with diode array [6] or UV 5 spectrophotometric detector [7,8]. Gas chromatography (GC) is frequently 6 utilized in connection with electron capture detector [9,10].…”

Electrochemical reduction of systemic fungicide azoxystrobin, used to protect a wide variety of crops, was investigated using cyclic voltammetry with a mercury meniscus modified silver solid amalgam electrode (m-AgSAE). Mechanism of the electrochemical reduction was proposed and supported with high performance liquid chromatography/mass spectrometry analysis of azoxystrobin solutions electrolyzed on mercury pool electrode. An analytical method for the determination of azoxystrobin by differential pulse voltammetry with m-AgSAE was developed. The wide linear dynamic range (2.0×10 −6 -5.0×10 −5 mol dm −3 ) and low limit of detection (7×10 −7 mol dm −3 ) were obtained. Accuracy and repeatability of the proposed method was evaluated by the analysis of model solutions with recovery from 96.0 to 104.0 % and relative standard deviation of 5 repeated determinations < 3.5 %. Finally, new voltammetric method using m-MCCM_Template_Vers 4

“…The analysis was always proceeding by separation procedure when the analyte was isolated from the matrix most often by solid phase/liquid or liquid/liquid extraction. To determine AS in various samples, specific methods using gas chromatography with an electron capture detector , high performance liquid chromatography with UV spectrophotometric or diode array detector , and micellar electrokinetic chromatography with UV spectrophotometric detector were described in literature. Chromatography is often combined also with mass spectrometry for the purposes of AS determination .…”

Electrochemical oxidation of azoxystrobin, a systemic fungicide commonly used in agriculture to protect a wide variety of crops, was investigated using cyclic voltammetry with a boron‐doped diamond electrode (BDDE) in aqueous buffer solutions. Two pH independent irreversible anodic current peaks controlled mostly by diffusion were observed in wide pH range (2 to 12) at potentials +1600 mV and +2150 mV vs. saturated silver‐silver chloride electrode. Mechanism of the electrochemical oxidation was proposed and supported with high performance liquid chromatography/mass spectrometry analysis of azoxystrobin solutions electrolyzed on carbon fiber brush electrode. The main product of the first two‐electron oxidation step was identified as methyl 2‐(2‐{[6‐(2‐cyanophenoxy)pyrimidin‐4‐yl]oxy}phenyl)‐2‐hydroxy‐3‐oxopropanoate. An analytical method for the determination of azoxystrobin in water samples and pesticide preparation by differential pulse voltammetry with BDDE was developed. The method provides a wide linear dynamic range (3.0×10−7 to 2.0×10−4 mol L−1) with limit of detection 8×10−8 mol L−1. Accuracy of the method was evaluated by the addition and recovery method with recoveries ranging from 96.0 to 105.8 %. Interference study proved sufficient selectivity of the developed voltammetric method for the azoxystrobin determination in presence of azole fungicides as well as pesticides used to prevent the same crops.
