Development and Validation of Spectrophotometric Method for Determination of Oxyfluorfen Herbicide Residues

A review of analytical methods for the determination of herbicide residues from the group of nitrodiphenyl ethers in the environment and agricultural products, developed and validated a method for oxyfluorfen determination in soybean grain and oil method GC/ECD, which meets regulatory requirements and solves the problem of toxicant control in the above matrices. The developed method uses modern methods of sample preparation, identification and quantification of oxyfluorfen (selective extraction, capillary gas-liquid chromatography (GC/ECD GC/MS). The method is validated according to EU requirements) (SANTE/12682/2019 quality control and analytical validation procedures for pesticide residues analysis in food and feed). Key words: gas-liquid chromatography, mass spectrometry, herbicides, nitrodiphenyl ethers, control, residual amounts.

Imidacloprid is an insecticide for the control of green peach aphids on selected fruits and vegetables. Spinach (Spinacia oleracea) is used as a functional food for its wholesome nutritional, antioxidants and anti-cancer composition. In the present study, HPLC technique is applied to detect Imidacloprid residues in fresh Spinach, when treated with legal and illegal doses by some farmers. Samples of fresh bio-vegetables were bought and divided into three groups (blank, group treated with legal dose and group treated with illegal dose of Imidacloprid). Freeze-dried samples were extracted with ethyl acetate, filtered and evaporated till dryness. Interestingly, comparison of antioxidant activity of organic spinach sample (not exposed to pesticide) with treated samples (propylgallate positive control having 100% antioxidant activity) showed reduction of antioxidant activity for the treated samples (spinach sample with illegal dose) but slightly higher in spinach sample with legal dose. These results indicate a lower nutritional quality of the treated Spinach with illegal doses.

Development and Validation of Spectrophotometric Method for Determination of Oxyfluorfen Herbicide Residues

Abstract: European Community Directive fixes allowable levels of pesticides in drinking water to 0.1 ng/mL for individual pesticide and some of their degradation products, and 0.50 ng/mL for the sum of all pesticides [7]. Therefore, it is of essential importance to set up reliable
