“…Compared with these literatures, the LOQ of this study was within the acceptable range for pesticide residues. In addition, the concentrations of organochlorine and organophosphate pesticide residues in fresh fruits and vegetables available were monitored, and a total of 38 pesticide residues were identi ed, and mean concentration (fresh weight) of organochlorine residues ranging from 0.02 to 0.37 mg/kg and organophosphate residues ranging from 0.01 to 0.33 mg/kg (Omeje et al 2022). Organophosphorus and organochlorine pesticide residues in fresh vegetables and fruits under smallholder horticultural production systems were determined (Kapeleka et al 2020), and pirimiphos-methyl, endosulfan (beta), profenofos, chlorpyrifos, and dieldrin were detected with the concentration ranging of 0.0003-1.4093 mg/kg, 0.0008-2.3416 mg/kg, 0.0176-2.1377 mg/kg, 0.0004-1.2549 mg/kg, and 0.0011-0.5271 mg/kg, respectively.…”

This study applied comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-TOF-MS) for the analysis of 100 pesticides (77 organophosphorus and 23 organochlorines) in six typical plant matrices with high protein, starch, acid, or oil content. Different sorbents were evaluated in the clean-up step of the QuEChERS method, and the optimized sorbent combinations were obtained for each individual matrix. Good linearity of the calibration curves of matrix-matched was obtained (R2 ≥ 0.9853). The mean recoveries and relative standard deviations at fortification levels of 10 and 50 μg/kg ranged from 72.6 to 117.5% and 0.1 to 19.9%, respectively. Phenolic antioxidants, glycosides, phosphorus esters, linoleic acid, unsaturated fatty acids, and other interferences in individual plant matrix were identified. The results demonstrated that GC×GC-TOF-MS is helpful in separation of the co-eluted pesticides and the identification of interferences in complex plant matrices.

Based on the results of pesticide determinations in these studies, it is believed that the present study has the potential to determine organophosphorus and organochlorine pesticides in plant-derived samples.…”

“…Omeje et al. (2022) found several organophosphorus and organochlorine pesticide residues in fresh fruits in a Nigerian market, some of them are even legally prohibited, such as linuron, propiconazole, and chlorpyrifos (Kazimierczak et al., 2022). In addition to fresh fruits, pesticides were also detected in some processed fruit products.…”

The binding of pesticide residues and fruit components may have a profound impact on pesticide dissipation and the functional characteristics of the corresponding components. Therefore, the interaction between boscalid and tannic acid (TA, a representative phenolic in fruit) was systematically investigated using spectroscopic, thermodynamic, and computational chemistry methods. A separable system was designed to obtain the boscalid-TA complex. Fourier transform infrared and 1 H-NMR spectroscopies indicated the formation of hydrogen bonds in the complex. Isothermal titration calorimetry showed that the complex bound spontaneously through hydrophobic interactions (ΔG < 0, ΔH > 0, ΔS > 0), with a binding constant of 6.0 × 10 5 M −1 at 298 K. The molecular docking results further confirmed the formation of hydrogen bonds and hydrophobic interactions in the complex at the molecular level, with a binding energy of −8.43 kcal mol −1 . In addition, the binding of boscalid to TA significantly decreased the antioxidant activity of TA. The binding of boscalid residue to TA was characterized at the molecular level, which significantly reduced the in vitro antioxidant properties of TA.
