“…Thus far, there are many methods to detect TM. The routine food quality and safety analytical methods are gas chromatography (GC), high-performance liquid chromatography (HPLC), mass spectrometry (MS) and capillary electrophoresis (CE) [ 38 , 39 , 40 , 41 ], but they all have the disadvantages of expensive instrument cost and time-consuming operation. Therefore, it is urgent to build an efficient and fast TM-detection method.…”

The detection of food safety and quality is very significant throughout the food supply. Stable dual-emission copper-modified fluorescent carbon dots (Cu-CDs) were successfully synthesized by a simple and environment-friendly hydrothermal, which was used for the real-time detection of pesticide residues in agricultural products. By optimizing the reaction conditions, Cu-CDs showed two emission peaks, with the highest fluorescence intensities at 375 and 450 nm. The structure, chemical composition and optical properties of Cu-CDs were investigated by XRD, TEM and IR. The results showed that thiophanate methyl (TM) could induce fluorescence quenching of Cu-CDs with no other ligands by the electron transfer through π-π stacking. The synchronous response of the dual-emission sensor enhanced the specificity of TM, which showed remarkable anti-interference capability. The fluorescence quenching degree of Cu-CDs had a good linear relationship with the TM concentration; the low detection limit for a pear was 0.75 μM, and for an apple, 0.78 μM. The recoveries in the fruit samples were 79.70–91.15% and 81.20–93.55%, respectively, and the relative standard deviations (RSDs) were less than 4.23% for the pear and less than 3.78% for the apple. Thus, our results indicate the feasibility and reliability of our methods in detecting pesticide residues in agricultural products.

“…The analysis of pesticide residues in food samples typically involves utilizing liquid chromatography (LC) and gas chromatography (GC) coupled with various detectors, such as mass spectrometry (MS), tandem mass spectrometry (MS/MS), and electron capture detector (ECD). In the determination of pesticide residues in dates, LC-MS/MS 3,4,27 , GC-MS 14 , and GC-MS/MS 28 have been employed. However, analyzing dates poses challenges due to the presence of numerous interfering compounds that signi cantly impact the analysis and the overall performance of the analytical method.…”

This study aimed to investigate carbamate pesticide residues in different varieties of date palm fruits in the UAE, utilizing UHPLC-MS/MS. For sample preparation and clean-up, the efficiency and performance of different QuEChERS dispersive solid-phase extraction kits were compared. Precision and recovery were assessed at 10 𝜇g kg-1 for the three kits, revealing that Kit 2 demonstrated the best performance. The selected QuEChERS method was validated to detect 14 carbamate residues in 55 date samples. The method exhibited strong linearity with R2>0.999 and low LOD (0.01- 0.005 𝜇g kg-1) and LOQ (0.003- 0.04 𝜇g kg-1). Excellent accuracy (recovery: 88-106%) and precision (RSD: 1-11%) were observed, with negligible matrix effect (-4.98-13.26%). All samples contained at least one carbamate residue. While the majority of detected residues were below their MRLs, carbosulfan was found in 21 samples, propoxur in 2 samples, and carbofuran in 1 sample above their MRLs. To assess potential health risks for date consumers, the hazard index (HI) was calculated for carbosulfan, phenmedipham, carbaryl, propoxur, carbofuran, and methomyl. All HI values were below the safety limit of 1.0, indicating that the consumption of dates does not pose a non-carcinogenic health risk for adults and children.
