“…Correlation coefficients were greater than 0.9953 and the lowest spiked level (0.5 mg kg -1 ) taken as the limit of quantification that meets the method validation criteria [20]. Recovery for azoxystrobin analysis in strawberries was 96-111%, and the RSD was below 11% [21]. The selectivity of the method was evaluated by analysing the unspiked samples.…”

In this study, 9 active substances that could be analysed by Gas Chromatography-Mass Spectrometer (GC/MS) were used. Changes in these pesticide residues were determined after strawberries were washed, pasteurized, stored in cold and washed on different days. In addition, strawberry puree was stored at -18±2ºC and pasteurized puree was stored at different temperatures. The highest and lowest processing factors in the pasteurization process were determined in tebufenpyrad (Pf:1.20) and tetraconazole (Pf:0.81), respectively. During cold storage, kresoxim-methyl degradation was found statistically significant (p

“…Compared with our indoor low-temperature and light-proof environment, after applying pesticides in grape fields, the effects of temperature, light, and precipitation may accelerate the degradation process. Volatilisation, wash-off, plant growth, photolysis, pesticide physicochemical properties, chemical decomposition, and metabolism due to oxidation and hydroxylation, are all factors that play important roles in the limitation of pesticide residues in plants [46,47]. In addition, the activity of microorganisms in the soil and the adsorption of organic matter can also help degrade residual pesticides [48].…”

The chemical fungicide fludioxonil is widely used to control post-harvest fungal disease in cherries. This study was implemented to investigate the dissipation behaviours and residues of fludioxonil on cherries. A reliable and efficient analytical method was established. Cherry samples from four product areas were analyzed by QuEChERS and HPLC-MS/MS methods with acceptable linearity (R2 > 0.99), accuracy (recoveries of 81–94%), and precision (relative standard deviation of 2.5–11.9%). The limits of quantification (LOQs) and limits of detection (LODs) of cherries were 0.01 mg/kg and 0.005 mg/kg. The dissipation of fludioxonil on cherries followed first order kinetics with half-lives of 33.7–44.7 days. The terminal residues of fludioxonil were all lower than 5.00 mg/kg, which is the MRL recommended by the European Commission. According to Chinese dietary patterns and terminal residue distributions, the risk quotient (RQs) of fludioxonil was 0.61%, revealing that the evaluated cherries exhibited an acceptably low dietary risk to consumers.
