“…Solid-phase extraction, supercritical-fluid extraction, liquid-liquid extraction and QuEChERS are generally adopted in paddy sample preparation, and QuEChERS is the most frequently used method [26]. Analytical methods for pyrazosulfuron-ethyl and bensulfuron-methyl have been mainly focused on high performance liquid chromatography (HPLC) [27], capillary electrophoresis (CE) [28], gas chromatography-tandem mass spectrometry (GC-MS) [29], immunoassay [30], and liquid chromatography-tandem mass spectrometry (LC-MS) [31]. Acetochlor and butachlor analysis have been primarily performed on GC [32], HPLC [21], and GC-MS [33].…”

The dissipation dynamics and residue of pyrazosulfuron-ethyl, bensulfuron-methyl, acetochlor, and butachlor in paddy fields at Good Agricultural Practices (GAP) condition were carefully investigated in this study. The four herbicides’ residues were determined based on a quick, easy, cheap, rugged, safe (QuEChERS) method coupled with HPLC-MS/MS and GC-MS. The limit of detection (LOD) for pyrazosulfuron-ethyl, bensulfuron-methyl, acetochlor, and butachlor in all matrices ranged from 0.04–1.0 ng. The limit of quantification (LOQ) of the four herbicides ranged from 0.01–0.1 mg/kg. Moreover, the average recoveries of the four herbicides ranged from 78.9–108% with relative standard deviations (RSDs) less than 15% at three different fortified levels for different matrices. The dissipation results indicated that the average half-lives (t1/2) of the four herbicides in soil were in the range of 3.5–17.8 days, and more than 95% of the four herbicides dissipated within 5 days in water. Furthermore, the final residues of the four herbicides were all below the LOQ at harvest time. Such results highlight the dissipation dynamics and residue of the four herbicides in a rice cropping system and contribute to risk assessment as well as scientific guidance on the proper and safe application of herbicides in paddy fields.

“…Several techniques of sample preparation, enrichment, and purification, up to isolation of sulfonylureas have been described. Many of them are based on solid-phase extraction (SPE) (Carabias-Martinez et al 2004;Seccia et al 2011), dispersive solid-phase extraction (DSPE) combined with dispersive liquid-liquid microextraction (DLLME) (Wu et al 2009), molecularly imprinted SPE (She et al 2010), or matrix soil-phase dispersion (MSPD) (Liang et al 2014;Łozowicka et al 2009). Most published methods involve liquid-soil extraction (LLE) Noche et al 2011) or salting-out liquid-liquid extraction (SALLE) (Nanita and Padivitage 2013).…”

A one-step quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based approach to extraction and cleanup in multiresidue pesticide analysis is presented for the first time. The experiment was designed to detect 23 sulfonylurea herbicides in a complex cereal matrix. The challenge was to choose the optimal conditions of one-step extraction and cleanup. Chitin, diatomaceous earth, and octadecyl were investigated as cleanup sorbents. Chitin, citrate buffer, and 1 % formic acid in acetonitrile yielded the best results. The effectiveness of sulfonylureas extraction was evaluated at three different spiking levels (0.005, 0.05, and 0.5 mg kg −1 ) in wheat, rye, and oat using liquid chromatography-tandem mass spectrometry. The one-step QuEChERS provided recoveries in the 70-120 % range for 23 sulfonylureas in all cereal matrices. Matrix effects were evaluated and were not significant for all herbicides, showing suppression or enhancement (between −19 and 13 %). Precision, calculated as relative standard deviation (RSD), was below 20 %. A linear dependence was observed in the range of 0.005-2.0 mg kg −1 , and the correlation coefficient was R 2 > 0.999. Expanded measurement uncertainty was estimated to be between 9 and 24 %, on average. The validated method was employed in analysis of 89 real grain samples.

“…Several methods have been developed in the search of new techniques in the pretreatment in food samples such as QuEChERS [1][2][3][4], supercritical fluid extraction (SFE) [5], pressurized fluid extraction (PFE) [6], microwave-assisted extraction (MAE) [7,8], matrix solid-phase dispersion (MSPD) [9][10][11], solidphase extraction (SPE) [12][13][14][15][16][17][18], and solid-phase microextraction (SPME) [19,20]. All these separation techniques have been applied to preparation of different food samples (e.g., fruits, juices, vegetables, milk, grain, and meat).…”

Magnetic solid phase extraction has been used as pretreatment technique for the analysis of several compounds because of its advantages when it is compared with classic methods. This methodology is based on the use of magnetic solids as adsorbents for preconcentration of different analytes from complex matrices. Magnetic solid phase extraction minimizes the use of additional steps such as precipitation, centrifugation, and filtration which decreases the manipulation of the sample. In this review, we describe the main procedures used for synthesis, characterization, and application of this pretreatment technique which were applied in food analysis.
