“…The half-lives were in the range from 1.3 to 1.6 days. The results were similar to the half-lives of thiamethoxam in tomato (2.34 days) [ 24 ], goji berry [ 10 ] (1.01–1.08 days), cowpea [ 11 ] (0.8–1.6 days), and citrus [ 16 ] (1.9 days), reported by previous studies. For the Shandong site, the dissipation rate of thiamethoxam was more rapid than at the other three sites.…”

“…To date, many studies have been carried out on the dissipation behavior and dietary risk assessment of thiamethoxam and clothianidin on different matrices, including gogi berry [ 10 ], cowpea [ 11 , 12 ], strawberry [ 13 ], apple [ 14 , 15 ], citrus [ 16 ], mango [ 17 ], wheat [ 18 ], lettuce [ 18 ], and tomato [ 18 ]. For example, Rahman et al found that half-lives on Swiss chard were in reverse order of initial deposition [ 3 ].…”

“…For example, Rahman et al found that half-lives on Swiss chard were in reverse order of initial deposition [ 3 ]. Li et al reported that initial concentrations of thiamethoxam in goji berry ranged from 0.297 to 0.720 mg kg −1 with half-lives from 1.01 to 1.08 days, demonstrating rapid degradation of thiamethoxam [ 10 ]. Fan et al investigated the dissipation behavior and dietary risk assessment of thiamethoxam on apple.…”

Thiamethoxam and its metabolite clothianidin residues pose a potential threat to human health. This study aims to investigate the residue behavior and acute dietary risk assessment of thiamethoxam and clothianidin on spinach. Thiamethoxam and clothianidin were extracted using a quick, easy, cheap, effective, rugged, safe (QuEChERS) method and analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). At spike levels from 0.01 to 5 mg kg−1, the average recoveries of both analytes were in the range of 94.5–105.5%, with relative standard deviations (RSDs) of 3.8–10.9%. The dissipation behavior of thiamethoxam followed first-order kinetics, with half-lives of ≤1.6 days. Clothianidin appeared readily as a plant metabolite with highest level exhibited during 3 to 5 days after application. Temperature and light may be two main factors for degradation of thiamethoxam. Besides, acute risk assessment of thiamethoxam and clothianidin was evaluated with risk quotients (RQs) <100%, which suggested a low health risk for all consumer groups of Chinese residents.

“…1,2 But it cannot be ignored that potential threat to the environmental risks and human health associated with thiamethoxam is still being assessed. 3 To date, a variety of methods, such as fluorimetry, 4,5 high performance liquid chromatography (HPLC), 6,7 capillary liquid chromatography (CLC) 8,9 and mass spectrometry (MS) [10][11][12] have been established to analyses thiamethoxam residue in different samples. Owing to its high sensitivity, rapid response, low-cost and on-site applications, electrochemical sensing methods have been also used to analyses thiamethoxam.…”

On the surface of a glassy carbon electrode, electrochemically reduced graphene oxide-cationic pillar[6]arene (ErGO-CP6) composite film was constructed using a pulsed potential method. UV–vis spectra, SEM, Raman spectra and electrochemical experiments were applied to characterize the composite film. It was then used as a new electrochemical sensing platform for determination of thiamethoxam. Due to the synergistic effect of ErGO and CP6, this composite film shows a higher sensitivity and better selectivity toward thiamethoxam than that of ErGO film. The linear range from 1.0 × 10−7 to 1.3 × 10−5 mol l−1 was obtained by differential pulse voltammetry. Meanwhile, the method was applied to cucumber and tomato samples in a recovery test. The recovery was between 92.0% and 98.7%, and the results are satisfactory. This study presents a promising electrochemical sensing platform for rapid and sensitive analysis of thiamethoxam.
