“…Furthermore, the simultaneous determination and evaluation assisted in a deeper understanding of the three residue and safety behaviors on the crop of grape. The importance of this work was illustrated by the following aspects: As there was no simultaneous determination of these three, this work provided an effective determination method. As there was no dissipation study in grape for cyazofamid, this work provided valuable half‐life and risk evaluation data. In this work, the half‐life and risk evaluation also verified previous research in grape and guaranteed the safe usage of pyraclostrobin. Terminal residues in this work were all below 0.5 mg kg −1 . Considering their MRLs in different regions in the range 1–2 mg kg −1 , it is possible to lower the updated MRLs in the future. Although the risk evaluation took China as an example, the conclusion could be extended to other regions with the main replacement of average weight of other region or country.…”

“…Besides, attention has been paid to the change of pyraclostrobin in food processing such as rasin and paste preparation. In addition, dissipation studies have been conducted in apple, pepper, peanut, banana, grape, giving half‐lives of 1.6 to 1.7 days in maize, 3.39–4.06 days in glasshouse strawberry, 10.3–11.2 days in peanut, 17.8–25.9 days in grape …”

“…Up to now, dietary risk of pyraclostrobin via rice and grape and cyazofamid via tomato have been reported. There were no evaluation report about risk of those three in grapes, especially cyazofamid and CCIM, which represented an uncertainty of its risk to human health.…”

“…3 Different methods have been developed for the determination of pyraclostrobin, for example, gas chromatography which requires cumbersome sample preparation and large amounts of organic solvents. 4,5 Capillary electrophoresis 6 and subsequent liquid chromatography (LC) UV 7,8 and mass spectrometry (MS) [9][10][11][12][13][14] have been utilized for the determination of pyraclostrobin in different matrices, such as apple, 10 citrus, 11 pepper, 12 peanut, 13 rice, 14 grape. 9 Besides, attention has been paid to the change of pyraclostrobin in food processing such as rasin 15 and paste 16 preparation.…”

BACKGROUND Grape is an important fruit consumed either fresh or processed, therefore, fungicide misuse of grape has become an issue of global food safety and human health. Pyraclostrobin, and cyazofamid have been applied to grape frequently. RESULTS Here a simple QuEChERS (quick, easy, cheap, effective, rugged, and safe) liquid chromatography mass spectrometry technique has been developed and validated for the determination of pyraclostrobin, cyazofamid and its metabolite CCIM in open field grape samples. The recoveries of these three in the range of 0.01 to 5 mg kg−1 (n = 5) ranged from 73.1% to 97.9%. The relative standard deviations (RSDs) were below 12% for all cases. The limits of quantitation of each analyte was 0.005 mg kg−1, which was lower than maximum residue limits of not only pyraclostrobin but also cyazofamid. Not only dissipation kinetics but also residue determination was obtained in grape for those three pesticides. Furthermore, their half‐lives in grapes were 10.7–30.1 days, recommending the pre‐harvest intervals for these three of 14 days. The calculated hazard quotient and acute hazard index lower than 100% illustrated the safety of intake of grape for the Chinese population for not only long‐term but also short‐term dietary risk assessment. CONSLUSIONS The less than 30 day half‐life illustrated that pyraclostrobin and cyazofamid could degrade relatively easily in the environment. The long‐term and short‐term dietary risk assessment also illustrated the intake safety of these three. Thus, a 14 day pre‐harvest interval was safe and recommended. The results of this study contributed to environmental protection, food safety and human health. © 2019 Society of Chemical Industry

“…Pyraclostrobin and azoxystrobin are widely used, and their residues and dissipative behavior on cucumber, tomato, grape, and soil have been reported previously (Chen, He, et al, ; Chen, Qian, Zheng, & Zhang, ; Jiménez‐López, Llorent‐Martínez, Ortega‐Barrales, & Ruiz‐Medina, ). The concentration of azoxystrobin in agricultural products and environment (water and soil) was mainly determined using HPLC‐UV (Ali, Ashour, Tohamy, & Ragheb, ), GC‐ECD (Bagi et al, ), GC–MS (Melo et al, ), and LC–MS/MS (Lazartigues et al, ).…”

Using LC–MS/MS, a rapid and sensitive method for the simultaneous determination of pyraclostrobin and azoxystrobin residues in banana matrices (leaf and whole banana) and soil was established. The samples were extracted using acetonitrile and purified through C18 dispersive solid‐phase extraction. The average recovery of the analytes in various matrices was in the range of 77.3%–103.9% with an RSD range of 0.9%–9.5%. The initial deposition amounts of pyraclostrobin and azoxystrobin at 2 h in the banana leaves of the mineral oil group were 1.43 and 1.31 times in Guangxi, and 2.10 and 1.81 times in Hainan for the water group, whereas those in the soil of the water group were 3.45 and 3.03 times in Guangxi, and 2.14 and 3.48 times in Hainan for the mineral oil group. The half‐lives in the leaves and soil of the mineral oil group were not remarkably different from those of the water group. The terminal residue of the analytes on the whole banana was <0.02 mg/kg at 14 days after application from the two sites. The results of this work may indicate and promote the safety of using pyraclostrobin and azoxystrobin in banana production, especially with mineral oil spray adjuvants.

BACKGROUNDCyromazine and acetamiprid are widely applied as pesticides in agriculture, causing increasing concerns about their residues in crops. In this study, cyromazine, acetamiprid and their mixture were applied to cowpea to investigate their degradation dynamics and perform a dietary risk assessment.RESULTSThe dissipation behavior of cyromazine and acetamiprid in the single‐ and mixed‐pesticide groups followed first‐order kinetics, with a linear correlation coefficient of 0.910 to 0.987. The half‐lives of cyromazine and acetamiprid were 1.56–11.18 days in the four different matrices. The half‐life of cyromazine in the mixed‐pesticide group was similar to or even shorter than that in the single‐pesticide group. The highest levels of cyromazine and acetamiprid in cowpea occurred with a preharvest interval of 7 days and after two or three applications. These levels are below the maximum residue limits recommended by the Chinese Ministry of Agriculture for cyromazine and acetamiprid in cowpea. The risk quotient of cyromazine and acetamiprid ranged from 0.0018 to 0.0418, and the national estimated short‐term intake values of the cyromazine and acetamiprid were far below the acute reference dose as recommended by the European Food Safety Authority.CONCLUSIONThese results suggest that the use of cyromazine and acetamiprid and a cyromazine–acetamiprid mixture in cowpea is safe under the Good Agricultural Practices for Chinese fields, and the use of a cyromazine–acetamiprid mixture affords even better results than the application of cyromazine alone. Moreover, the residue dynamics information will support the label claims for the application of cyromazine, acetamiprid and a cyromazine–acetamiprid mixture to cowpea fruit. © 2020 Society of Chemical Industry
