MIL-101(Cr) based d-SPE/UPLC-MS/MS for determination of neonicotinoid insecticides in beverages

Fabrication of Nitrogen Based Magnetic Conjugated Microporous Polymer for Efficient Extraction of Neonicotinoids in Water Samples

“…For a further evaluation of the analytical performance of the proposed method, it was compared with other methods reported in the literature (Table 3). Compared with SPME-UPLC-MS/MS [17], DSPE-UPLC-MS/MS [18,19], and MSPE-HPLC-MS [25,52], the current MSPE-HPLC-DAD method displayed higher LODs, because the MS detection promoted higher sensitivity towards NEOs than DAD detection. However, MS detection is more expensive than DAD detection.…”

“…The direct determination of NEOs is extremely difficult because of their low concentration in complex matrices. Appropriate sample pretreatment methods such as solid-phase extraction (SPE) [14], solidphase microextraction (SPME) [17], dispersed solid-phase extraction (DSPE) [4,18,19], and magnetic solid-phase extraction (MSPE) [20] are necessary prior to chromatographic analysis. Among those methods, MSPE has generated widespread attention in the sample pretreatment field owing to its inherent advantages, including efficient extraction phenomenon, rapid separation, low consumption of organic solvents, and appropriate recycling of sorbents [21,22].…”

A comparison of the determination of multiple pesticide residues in fruits, vegetables, and edible fungi using gas chromatography combined with filtration purification and solid-phase extraction

“…[3][4][5] Common methods for testing pesticide residues include gas chromatography (GC), 6 liquid chromatography (LC), 7 gas chromatography-tandem mass spectrometry (GC-MS/MS), 8,9 liquid chromatography-tandem mass spectrometry (LC-MS/MS). 10,11 Mass spectrometry, known for its high selectivity and sensitivity, is particularly suited for detecting trace substances. However, its high equipment cost poses signicant operational nancial pressures on small and medium-sized laboratories.…”

Assessing the ecotoxicity of commercial formulation based on Imidacloprid on the non-target freshwater planarian Girardia tigrina

“…The origin of neonicotinoids (NNIs) can be traced back to 1990 (Taira et al 2021), and they continue to be the most prevalent class of synthetic insecticides used globally (PAN 2023; Siviter et al 2022) due to their high solubility, as well as their toxicity to target invertebrates (Yuan et al 2022), while posing low risks to mammals (Fan et al 2022). NNIs act on the insect's central nervous system (Jactel et al 2019;Liao et al 2022), functioning as agonists of acetylcholine through their binding to the nicotinic acetylcholine receptors (nAChR), and belong to Group 4 (competitive modulator) according to Insecticide Resistance Action Committee (IRAC 2015). Products of this class are used to combat a range of insect pests (such as Aphis gossypii, Frankliniella schultzei, Thrips palmi, Myzus persicae, Heterotermes tennuis, Thrips tabaci, Phyllocnistis citrella, Toxoptera citricida, Oncometopia facialis, Orthezia praelonga, Selenaspidus articulations, Thrips palmi) in seed treatment, as well as in the spraying of crops, providing systemic protection (Berheim et al 2019; UPL 2017).…”
