“…As a result, 250, 247, 262, and 237 pesticide targets gave ideal recoveries at each of the spiked levels in red onion, pakchoi, king oyster mushroom, and black tea, respectively (Tables S6–S9). As shown in Table S10, the developed method was compared with other methods based on QuEChERS, dispersive liquid–liquid microextraction (DLLME), and solid-phase micro-extraction (SPME), suggesting a satisfactory performance of the automated workflow. − …”

Robots replacing humans as the executioners is crucial work for intelligent multi-pesticide residue analysis to maximize reproducibility and throughput while minimizing the expertise required to perform the entire process. Traditional analysis methods are predicated on manual execution, so we configured our robot experimenter, automated the analytical workflow, and achieved the goal of robotics execution. Our robot experimenter with an X−Y−Z axis robotic arm was interfaced with seven modules and ultra-performance liquid chromatography−tandem mass spectrometry (UPLC−MS/MS) for automated standard solution preparation, sample pre-treatment, and UPLC−MS/MS detection. An algorithm was established to make the prepared matrixmatched standard solutions meet the monitoring requirements. The strategy was demonstrated and validated for the detection of 325 pesticides in 4 typical food matrices, suggesting that the developed method is applicable for the analysis of pesticide residues in vegetables and tea as part of regulatory monitoring programs and other purposes.

“…Several previous studies have shown that all of the three versions (original, AOAC, and EN) of the QuEChERS method were effective for extraction and purification of thiacloprid in various matrices (Abdallah & Malhat, 2019; Chen et al, 2014; Song et al, 2019; Suganthi & Bhuvaneswari, 2018). Among them, best recovery was achieved through the QuEChERS EN method.…”

“…Accurate analysis of field‐supervised sample is necessary for IT MRL that might be an outcome of a robust method. Thiacloprid has been detected in various matrices using different analytical methodologies (Abdallah & Malhat, 2019; Banerjee & Banerjee, 2012; Banno & Yabuki, 2020; Chen, Tao, McLean, & Lu, 2014; Kovacova et al, 2013; Lazić, Šunjka, Begović, & Vuković, 2015; Sahoo, Mandal, Kaur, Battu, & Singh, 2013; Song, Yoo, & Nam, 2019; Suganthi & Bhuvaneswari, 2018; Wang, Guan, & Zhang, 2011; Yun‐long, Jia‐lun, Matthias, & Wilfried, 2007). Among them LC is the most commonly used instrument in combination with traditional or mass spectrometry detector.…”

To promote exports, import tolerance (IT) of thiacloprid in strawberry was proposed using the Organization for Economic Cooperation and Development (OECD) maximum residue limit (MRL) calculator after conducting three different field trials. The pre‐harvest interval of residual pattern and degradation dynamics of thiacloprid in strawberry were determined using ultra‐performance liquid chromatography–tandem mass spectrometry. Samples were extracted with acetonitrile and a mixture of salts and dilution was performed for purification. A six‐point matrix‐matched calibration curve was constructed which provided excellent linearity with coefficient of determination (R2) of 0.9998 or more. Detection and quantification limits were 0.003 and 0.01 mg/kg, respectively. The method was validated in quintuplicate at three different concentrations, which resulted in acceptable recovery ranging from 80.86% to 101.71% with relative standard deviation of 6.50 or less among the three field sites. The developed method was applied to the field‐treated sample harvested at different intervals. In the pre‐harvest interval trial, the amount of thiacloprid residues ranged from 0.24 to 0.70 mg/kg in field site 1 (Nonsan), 0.16 to 0.50 mg/kg in field site 2 (Sunchang), and 0.36 to 0.50 mg/kg in field site 3 (Sacheon). By contrast, in the degradation trial, the observed residues were 0.03–0.81 mg/kg in field site 1 and 0.02–0.48 mg/kg in field site 2. Consequently, the IT of thiacloprid in strawberry using the OECD MRL calculator was proposed as 2 mg/kg, which is exactly the same as the MRL established by the Republic of Korea. In conclusion, the residue study proposes 2.0 mg/kg as the MRL of thiacloprid in strawberries.

Insecticides are important to increase crop yields, but their overuse has damaged the environment and endangered human health. In this study, residues of spiromesifen and spirodiclofen were determined in tomato fruit using a simple and efficient analytical procedure based on acetonitrile extraction, extract dilution, and UPLC-MS/MS. The linearity range was 1–100 µg/kg and 0.5–100 µg/kg, and the correlation coefficient (R2) and residuals were ≥0.9991 and ≤16.4%, respectively. The limit of determination (LOD) was 0.26 and 0.08 µg/kg, while the limit of quantification (LOQ) was verified at 5 µg/kg. The relative standard deviation of spiked replicates at 5 µg/kg analyzed in one day (RSDr, n = 6) was ≤8.35%, and within three different days (RSDR, n = 18) it was ≤15.85%, with recoveries exceeding 91.34%. The method recovery test showed a satisfactory value of 89.23–97.22% with an RSD of less than 12.88%. The matrix effect was determined after a 4-fold dilution of the raw extract and was −9.8% and −7.2%, respectively. The validated method was used to study the dissipation behavior of the tested analytes in tomato fruit under field conditions. First-order kinetics best described the dissipation rates. The calculated half-lives were 1.49–1.83 and 1.91–2.38 days for spiromesifen and spirodiclofen, respectively, after application of the authorized and doubled authorized doses, indicating that spiromesifen dissipated more rapidly than spirodiclofen. The final residue concentrations of spiromesifen and spirodiclofen were 0.307–0.751 mg/kg and 0.101–0.398 mg/kg, respectively, after two or three applications, and were below the European Union (EU) maximum residue limits. The chronic risk assessment indicates that both insecticides are safe for adult consumers.
