“…Few information is present in the literature on the absorption and accumulation of these contaminants by plants. Gong et al (2020) ascribed the rapid absorption and translocation of metalaxyl-M in plants to both its hydrophilicity and the small molecular size that allowed an easy passage through cell membrane and Casparian strip. Perennial ryegrass and radish, exposed for 16 days to 4.6 and 46 μg mL −1 BPA concentrations, accumulated in dry plant mass, respectively, 0.8 and 2.7% of initial BPA at the lower dose and 0.2 and 0.4 % at the higher dose, indicating an efficient metabolization of this compound (Loffredo et al 2010).…”

“…Kubicki et al (2019), studying the dynamic of metalaxyl in tomato, reported that the compound was readily taken up by the roots with the normal water absorption and translocated uniformly to the aerial organs through the xylematic vessels. Very recently, Gong et al (2020) found that metalaxyl-M translocated rapidly in chrysanthemum plants where it accumulated mainly in the leaves and ascribed that to the relatively low log K ow .…”

Hemp (Cannabis sativa L.) seedlings were used to remove from water the fungicide metalaxyl-M and the endocrine disruptor (EDC) bisphenol A (BPA) at concentrations ranging from 2 to 100 μg mL−1. In 7 days of exposure, despite the phytotoxicity of each compound that reduced elongation and biomass, the seedlings were able to remove between 67 and 94% of metalaxyl-M and between 86 and 95% of BPA. The amounts of metalaxyl-M and BPA extracted from plant dry biomass were in the range of 106–3861 μg g−1 and 16–101 μg g−1, respectively, and resulted positively correlated to both the dose of compound added (P ≤ 0.01) and the amount removed by the plants (P ≤ 0.01). Plant uptake and transformation were the main mechanisms involved in the removal of the compounds. In another set of experiments, hemp was used to remove a mixture of two pesticides, metalaxyl-M and metribuzin, and three EDCs, BPA, 17β-estradiol (E2), and 4-tert-octylphenol (OP), at concentrations of 10, 10, 10, 10, and 1 μg g−1, respectively, from soil column not added and added with 2.5% (w/w) of a green compost (CM) or a wood biochar (BC). In 25 days, plants did not alter considerably the distribution of the compounds along the soil profile and were capable of removing, on average, 12, 11, 10, 9, and 14% of metalaxyl-M, metribuzin, BPA, E2, and OP, respectively. During growth, hemp transformed the compounds and accumulated part of them (except OP) mainly in the shoots. CM and, especially, BC significantly protected the plants from the toxicity of the compounds and enhanced the retention of the latter in soil, contrasting leaching. Thus, the single or synergistic use of hemp and amendments deserves attention being a very low-cost and eco-sustainable strategy to remediate water and soil.

“…Several sample pre-concentration procedures have been proposed for pesticide residue determination in fruits and vegetables, including: solid phase extraction (SPE), solid phase micro-extraction (SPME), micro-solid phase extraction (µ-SPE), and microwave assisted extraction (MAE) [24]. While these methods are highly efficient, they generally require considerable investment in instrumentation and In previous studies, the retention time of fludioxonil in a single sample was in the range of 5-12.75 min [13,15,18,23], while the retention time of fludioxonil in this method was only 1 min. It can be seen that when a large number of samples need to be processed, this method can improve work efficiency by shortening the average detection time of a single sample.…”

“…Therefore, the toxicity of fludioxonil at relevant concentrations and dietary intake risk have attracted people's attention to its safety. There are several studies on the residues of fludioxonil in grapes [13], tomatoes [14], and chrysanthemum [15] in field; and citrus [16], nectarines, apricots, and peaches [17] when it was the preservative. However, there are rare reports about the residues and dissipation behaviour of fludioxonil on the matrix of the cherry as an indoor preservative.…”

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.

“…The studies are restricted to a limited number of active ingredients and selected commodities such as fruits and vegetables, for the most part, [22][23][24][25][26][27][28] rarely herbs or environmental matrices. [29][30][31][32] A few scientific articles refer to BOS and PYR in terms of their residue behavior, mainly in grapes, [33][34][35][36] cucumber, 37 lettuce 27 and wheat. 38 Another problem of minor crops is that the MRLs are not set for a specific pesticide in the processed product, and unique matrices are very often given as a general product to which MRLs apply.…”

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.
