“…In previous reports, pymetrozine residues could be extracted from samples using acetonitrile (Dias et al, ; Jang et al, ; Zhang et al, ). For example, Jang et al found that methyl cyanide (MeCN) is a better exaction solvent for pymetrozine in pepper than ethyl acetate (EtOAc).…”

“…As pymetrozine is widely used across the world, many papers on the analysis of pymetrozine in soils, terrestrial plants and meat products are available. Pymetrozine residues are usually extracted from different matrices using acetonitrile (Camino-Sanchez et al, 2010;Dias et al, 2013;Zhang, Zhang, Xu, Li, & Wang, 2015) and methanol (Hong, Cho-Rong, Jong-Sung, & Kyu-Seung, 2011). The extracts were cleaned up using solid-phase extraction (Zhao et al, 2014) or liquid-liquid partitioning with organic solvent such as dichloromethane (Zhang et al, 2015), ethyl acetate (Hong et al, 2011), or dispersive solid-phase extraction (Cabizza, Satta, Falconi, Onano, & Uccheddu, 2007).…”

The commonly used analytical instruments for pymetrozine are HPLC (De, Commissati, Gritti, Catellani, & Suman, 2015;Hong et al, 2011); LC-MS/MS (Camino-Sanchez et al, 2010;Dias et al, 2013;Fernandes et al, 2014) and GC (Jang et al, 2014). In addition, modified QuEChERS (quick, easy, cheap, effective, rugged and safe) sample preparation procedures have been successfully used to recover pymetrozine from beef (Oliveira, Pereira, Gobbi, Soto-Blanco, & Melo, 2018), coffee (Dias et al, 2013), strawberries (Fernandes et al, 2014), tomato, cucumber and watermelon (Camino-Sanchez et al, 2010).…”

The present study investigates the occurrence of pymetrozine residues in cauliflower samples obtained from six cauliflower‐producing areas of China during fixed time periods in 2017 and estimates the dietary risk of pymetrozine in cauliflower. A liquid chromatography with tandem mass spectrometry method was developed and validated to detect pymetrozine in cauliflower. The samples were extracted using 20 mL of acetonitrile and purified with dispersive solid‐phase extraction using C18 as sorbent. The limit of quantification of pymetrozine was 0.008 mg/kg in cauliflower. The recoveries of the analyte were 82.04–95.18% with RSD <8.45%. The calibration curves for pymetrozine showed good linearities in the concentration range 0.004–2.0 mg/L with determination coefficients (R2) >0.999. Pymetrozine dissipated rapidly in cauliflower with a half‐life of <4 days. The terminal residues of pymetrozine were <0.008–0.0881 mg/kg in cauliflower at 7, 10 and 14 days after spraying from six sites. The routine washing process removed about half amount of the pymetrozine in cauliflower; the reduction ratios were 51.0–52.8%. The dietary risk assessment indicated that pymetrozine did not exhibit obvious dietary health risks in cauliflower when good agricultural practices were implemented.

This study describes the synthesis and application of a magnetic amino-functionalized hollow silica-titania microsphere as a new sorbent for magnetic dispersive microsolid phase extraction of selected pesticides in coffee bean samples. The sorbent was fully characterized by Fourier-transform infrared spectroscopy, field emission scanning electron microscopy, transition electron microscopy, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometry techniques. Significant extraction parameters affecting the proposed method, such as extraction time, sorbent amount, sample solution pH, salt amount, and desorption conditions (desorption solvent and time) were investigated and optimized. All the figures of merits were validated in coffee bean samples under the matrix-matched calibration method. Linear dynamic ranges were 5-250 μg/kg with the determination coefficients (R 2 ) > 0.9980. The limits of detection for the pesticides of chlorpyrifos, malathion, hexaconazole, and atrazine were 1.42, 1.43, 1.35, and 1.33 μg/kg, respectively. Finally, the method was successfully applied for the determination of the pesticides in green and roasted coffee bean samples, and the obtained recoveries were in the range of 74-113% for spiked samples.The prepared sorbent could be used for the magnetic dispersive micro-solid phase extraction of pesticides in the plant-derived food matrix.

Determination and dissipation kinetics of pymetrozine and spirotetramat in green bean were studied using a QuEChERS method coupled to high-performance liquid chromatography-tandem mass spectrometry. Pymetrozine recoveries ranged between 88.4–93.7%, with relative standard deviation (RSD) of 5.5–14.4%. For spirotetramat the recoveries ranged between 91.7–103.4%, and the RSD were in the range of 3.2 to 12.4%. The limits of quantification (LOQs) were 0.01 mg/kg and 0.005 mg/kg for pymetrozine and spirotetramat, respectively.The developed analytical method was used to study the degradation rates of pymetrozine and spirotetramat in green bean grown in open field. Results showed that pymetrozine and spirotetramat followed the first-order kinetics model with half-lives of 3.3 days and 4.2 days, respectively. Furthermore, risk assessment was carried out which showed that, the chronic risk quotient (RQc) values for pymetrozine and spirotetramat were much lower than 100%. The present results indicated that the health risks posed for consumers by the pymetrozine and spirotetramat residues were negligible at the recommended dosages.
