“…The most frequently detected class of pesticide among the authorized active substances was fungicides. Some of them are already known to remain strongly retained in the soil such as fenbutatin oxide (Gray et al, 1995), boscalid (He et al, 2020) or benalaxyl (Qin et al, 2014). For others, such as buprofezin (Oulkar et al, 2009) or penconazole (Abd-Alrahman and Ahmed, 2012), a rapid degradation rate (especially in loamy soils) has been described, and its detection would point to a very recent use of these products.…”

“…According to other studies, first-order degradation kinetics were observed for BOS with decline over 2.67-9.90 days in cucumber. 24 In another study performed by Chen and Zhang, 22 the t 1/2 of BOS in strawberries was 4.9 and 6.4 days at the recommended and double dosages, respectively. According to Wołejko et al 27 the t 1/2 of BOS applied on lettuce was 3.2 days and PYR 4.1 days.…”

BACKGROUND: Determining the environmental behavior and fate of chemical compounds during technological processing of plants is a task of great significance nowadays. However, the current knowledge is still incomplete for unique herbal matrices belonging to minor crops. The research in this article presents, for the first time, the dissipation kinetics and processing behavior of carboxamide boscalid (BOS) and stobilurin pyraclostrobin (PYR) fungicides during glasshouse dill (Anethum graveolens L.) cultivation. RESULTS:The half-lives (t 1/2 ) of BOS and PYR after application at the recommended and double dosage were in the range: 1.62-2.01 days in plant and 2.08-4.85 days in soil, respectively. The processing behavior in dill was estimated after washing, hot air drying and drying in sunlight without/with pretreatment. Processing factors (PFs) were above 1 after drying (PF = 1.24-1.39 hot air; PF = 1.15-1.28 sunlight) and below this value when the washing step was applied (PF = 0.31-0.42 hot air; PF = 0.21-0.34 sunlight), indicating the highest effectiveness of reduction, up to 73% BOS and 79% PYR. CONCLUSION: BOS/PYR residues at pre-harvest intervals after both doses were below European Union (EU) maximum residue limits (MRLs). The highest effectiveness was noted for drying carried out with the washing step, which has a great influence on the concentration of residues in the final product. The findings can supplement PF databases not set for minor crops and can be used to establish MRLs and determine human exposures more accurately in risk assessment studies.

“…Therefore, monitoring and controlling the fungicide residues seems important to ensure fruits safety and quality since the public nowadays is more concerned about dietary risks (Li et al, 2020). Although plenty of researches have been performed to investigate the behavior of fungicides, the majority were focused on the fungicide distribution in the environment and soil under field conditions (He et al, 2019;Mohapatra and Lekha, 2016;Niu and Hu, 2018;Saber et al, 2016). There is still no enough research evidence available about the migration and distribution of fungicides in the fruit during storage.…”

Fungicides are often used to extend the storage time of postharvest satsuma mandarin fruit. In recent years, fungicide residue has become an issue of food safety. This study aimed to investigate the distribution and migration of three typical fungicides (imazalil, prochloraz, thiophanate-methyl) in postharvest satsuma mandarins using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Three fungicides could quickly penetrate satsuma mandarins and their gradient concentrations of residues in the fruit were: carpopodium > mesocarp > epicarp > pulp. However, the residues of three fungicides in the edible pulp were obviously lower than the maximum residue limit (MRL = 5.0 mg kg−1 in China). Residues of the three fungicides decreased in epicarp and carpopodium but increased in mesocarp and pulp during storage. Fungicides could quickly penetrate the fruit, settling primarily in the carpopodium but little in the pulp. Both epicarp and carpopodium were the breakthrough pathways for the fungicides entering the fruit, while epicarp was the main route for the penetration of fungicides. These findings shed new information on the behavior of fungicides and the safety issue of satsuma mandarins.
