“…The use of pesticides saves manpower, reduces labor intensity, alleviates diseases, controls pests and weeds, and facilitates mechanized operations. To ensure high crop production, farmers commonly apply pesticides (He, Wang, et al 2015). Therefore, large amounts of multiple pesticides in farmlands have contaminated ecosystems (Pang, Wang, and Hu 2016).…”

A simple and efficient procedure was developed to determine eight herbicides in corn flour by gas chromatography -mass spectrometry in selected ion monitoring mode. Samples were prepared with a modified quick, easy, rapid, effective, rugged, and safe procedure. The type and volume of extraction solvent, type and amount of adsorbent, and time of sonication were optimized. The protocol method was rigorously verified. The mean recoveries were from 85 to 108% at various fortification levels with relative standard deviations below 15% and limits of quantification from 4 to 48 ng/g. The method was employed to determine herbicides in corn flour.

“…Effective sample pretreatment procedure for extraction and purification is essential prior to analysis as pesticides occur in complicated matrices. At present, several pretreatment techniques such as supercritical fluid extraction (SFE) [5], accelerated solvent extraction (ASE) [6] and, matrix solid phase dispersion (MSPD) [7] and QuEChERS [14] are frequently and traditionally used for extraction of pesticides from fruits and vegetables. SFE is an extraction technology that utilizing the strong solubility of Supercritical Fluid (SCF), which has the dual characteristics as it is in a critical state between gas and liquid.…”

Abstract A simple, inexpensive and sensitive method was developed for the simultaneous determination of three pesticide residues (carbendazim, thiophanate-methyl, and imidacloprid) in fruit and vegetable samples using high performance liquid chromatography (HPLC) based on a combined pretreatment of ultrasound-assisted deep eutectic solvent extraction (UA-DES-E) and liquid-liquid extraction (LLE). In this study, various types of deep eutectic solvents (DESs) were synthesized and the extraction efficiency was compared as extraction solvents. Results showed that glycerol-proline = 9:4 (GP-5) obtained the highest extraction efficiency among different types of DESs. Experiment conditions, including DES volume, extraction time and pH, were systematically optimized using single-factor experiment. Under the optimum conditions, the limits of detection (LODs) and quantification (LOQs) were in the ranges of 0.05–0.2 μg·mL−1 and 0.1–0.5 μg·mL−1, respectively. The relative recoveries of the three pesticides in the fruit and vegetable samples ranged from 85.7 to 113.0% at two spiked levels. Meanwhile, the method achieved excellent linearity with determination coefficients (r) greater than 0.999. Furthermore, the method was successfully applied to the analysis of the pesticides in real fruit and vegetable samples (apple, tomato, and grape).

“…Many works concerning multiresidue analysis of over 200 or even over 400 pesticides in various matrices have been reported. [3][4][5][6][7][8] The QuEChERS (quick, easy, cheap, effective, rugged, and safe) method has been widely accepted by the scientific community as a pretreatment technique for fruits and vegetables since it was introduced in 2003 by Anastassiades et al 9 For pesticide detection, nowadays MS/MS, especially triple quadrupole (QqQ), has replaced traditional chromatographic detection systems (e.g., UV, fluorescence, ECD, FPD). Although routine monitoring of pesticide residue in fruits and vegetables has received great attention worldwide, the chirality characteristic has not been considered.…”

In this research, 10 chiral pesticides in fruits and vegetables were simultaneously determined using chiral liquid chromatography triple quadrupole-linear ion trap hybrid mass spectrometry (LC-QqLIT). The QuEChERS method was applied for sample preparation, and an enhanced product ion (EPI) scan was used to acquire tandem mass spectrometry (MS/MS) spectra for the library search. Parameters including limit of detection (LOD), limit of quantification (LOQ), linearity, relative standard deviation (RSD), and matrix effects were evaluated in five representative matrices (strawberry, leek, cowpea, tomato, and eggplant). Good linearity with coefficient of determination (r(2) ) ≥0.997 was obtained for all 20 enantiomers in these five matrices over the range from 1.0 to 250 µg L(-1) . All the recoveries at 5 and 50 µg kg(-1) (n = 5) ranged between 70% and 120% with RSD below 20%, indicating satisfactory precision. The LOQ for the enantiomers ranged between 0.05 and 1 µg kg(-1) . Based on the proposed method, 135 commonly consumed fruits and vegetables taken from markets in Guizhou province, China, were analyzed. Enantioselective degradation for the selected chiral pesticides was observed in most of the positive samples.
