“…5 Therefore, it is necessary to develop a highly sensitive, selective, rapid and reliable analytical method to determine phoxim for food quality control purposes. At present, some methods have been established for detection of phoxim such as high-performance liquid chromatography (HPLC), 4,[6][7][8][9] liquid chromatography-mass spectrometry, 10 enzymatic kinetic methods, 11 near-infrared spectroscopy 12,13 and spectrophotometry. 11 However, these reported methods require expensive and complicated instruments, time-consuming pretreatment steps and skilled operators.…”

“…After RP-HPLC separation target compounds was detected with tandem mass spectrometry in positive-ion electrospray ionization (ESI) mode RSDs of intra-and inter-day variations varied between 2.1% -6.7% and 2.8% and 6.4%for phoxim and DCTP, respectively. Recoveries ranged from 81.3% to 93.6% for phoxim and from 83.3% to 90.1% for DCTP [96]. Thiosultap sodium, thiocyclam, and nereistoxin were determined in pepper.…”

The newest results in the chromatographic analysis of pesrticides present in foods and food products are collected and the results are critically evaluated. Examples for the employment of preconcentration and prepurification technologies, gas chromatography using ECD, NPD, MS and MS/MS detection methods, liquid chromatographic methodologies such as thin-layer chromatography, high performance liquid chromatographic methods as well as electrically driven systems are presented. The advantages and disasdvantages of the various chromatographic technologies are shortly discussed and the efficacies of the methodologies are compared. Pesticides included in the review are insecticides, herbicides, acaricides, organophosphorous and organochlorine compounds The application of the chromatographic methods for the determination of pesticides in a wide variety foods and food products is discussed in detail.

“…Due to its unique insecticidal mechanism and high selectivity, it is safe and reliable for the environment and non‐target organisms. For example, when tebufenozide is widely applied on apples, cucumbers, grapes, tobacco, potatoes, and tomatoes, it is non‐toxic to mammals, fishes, birds and other natural enemies . It can improve the stress resistance of crops, enhance photosynthesis, improve the quality and increase the yield of plants.…”

“…Many studies have been conducted to determine tebufenozide in different matrices using many extraction methods including vortex, ultrasound, oscillation, and supercritical fluid extraction (SFE), pressurized liquid extraction (PLE), dispersive solid phase extraction (dSPE), hollow fibre liquid phase micro‐extraction (HF‐LPME), ionic liquid assisted liquid micro‐extraction (IL‐VALLME) and accelerated solvent extraction (ASE) . Several detection methods have been implemented for the analysis of tebufenozide including gas chromatography (GC), high‐performance liquid chromatography (HPLC), liquid chromatography with mass spectrometry (LC–MS), gas chromatography with mass spectrometry (GC–MS), liquid chromatography with tandem mass spectrometry (LC–MS/MS), gas chromatography with tandem mass spectrometry (GC–MS/MS), and micellar electrokinetic capillary chromatography .

BACKGROUND: Ensuring the yield, quality, and profitability of okra by preventing and controlling pests with the application of insecticides has increased in the last decade. Some insecticide residues might remain in edible parts of okra (fruits) and lead to several potential human health problems. Therefore, research on the residue behaviour, risk assessment and removal approach of insecticides on okra fruits is important for food safety, together with the proper application and residual elimination of insecticides in okra. RESULTS: A simple liquid chromatography with tandem mass spectrometry (LC-MS/MS) method was established and validatedfor determining the tebufenozide residues in okra fruits. The recoveries of tebufenozide in okra fruits were >72% with relative standard deviations of 0.6 to 6.1%. The dissipation rates of tebufenozide were different in okra fruits cultivated under open land and glasshouse field conditions because of the discriminating humidity and temperature conditions. The dietary intake of the tebufenozide residues from okra fruit consumption for Chinese consumers was fairly low, with approximately no potential health risk. The processing factor values of washing, blanching, washing + blanching and soaking were all less than one, which indicated that these processes could effectively reduce the residual hydrazide in the okra fruit. CONCLUSION: The developed method for analysing tebufenozide in okra fruits was applicable for field studies on this insecticide. The potential health risk of tebufenozide in okra fruits could be negligible to the health of different age groups of Chinese consumers. The soaking process effectively removed tebufenozide residues from okra fruits. The obtained data will help Chinese governments establish a maximum residue limit of tebufenozide in okra and provide data for the risk assessment and removal of tebufenozide in other crops.
