“…The residue of tebufenozide in okra significantly decreased, which provided another barrier to the health and safety of food. The results were consistent with the results of previous researches that the bioavailability factor reduced the initial concentration of pesticides by more than 50% . Compared with the data of these studies, the health risks of processed okra were extremely low.…”

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.

Evolution of fungicide residues in pruned vine-shoots

et al. 2021

Pruned vine-shoots used as wine additives have proven to be a useful tool for improving and differentiating wines. This is because they accumulate substances from the plant itself, which later, as a result of the toasting process, express their greatest oenological potential. However, vine being one of the crops subject to the most phytosanitary treatments, including fungicides in particular, it can be assumed that their residues will accumulate in the vine-shoots and pass into the wine. The aim of this study was to determine the content in pruned vine-shoots of four of the main fungicides applied in the vineyard in Spain: trifloxystrobin, boscalid, kresoxim-methyl and penconazole. In order to do so, a HPLC-MS/MS method was developed, which showed high reliability given its adequate validation parameters. The method was linear for the concentration range studied, LOD was 0.003 mg/kg and LOQ was 0.01 mg/kg, which comply with the control criteria.The evolution of residues in vine-shoots complying with critical agricultural practices and good agricultural practices was monitored at 1, 3 and 6 months of storage after pruning and, in the latter case, after being subjected to a toasting process. The dissipation of all the residues was demonstrated to be affected by storage duration and toasting. It was confirmed that converting vine-shoots into oenological additives for wines will not pose a risk to the consumer if good agricultural practices are applied.
