“…In this study, the LOD of 0.5 µg kg -1 was reached for the three soils and the LOQ of 2 µg kg -1 for the sandy soil and 3 µg kg -1 for the clayey and medium-textured soils. The LOD and LOQ values found are lower than those of other published studies such as those by Mahdavi et al, 11 respectively, as the LOQ. There is still no legislation in Brazil which determines the maximum residue limit of fluopyram in soil, but the results obtained revealed that the LOD and LOQ values were lower than the maximum residue limits established for pesticides by the European Union for several foods of plant origin, such as bananas, apples and watermelon with residue limits of 800, 600 and 400 µg kg -1 , respectively.…”

“…To the best of our knowledge, only the QuEChERS (quick, easy, cheap, effective, rugged and safe) method and solid-liquid extraction have been optimized and validated for this compound in soil. [6][7][8][9][10][11][12] Although these methodologies have proven to be very efficient and sensitive, the development of new extraction methods which can be simpler, easier to perform, sensitive, efficient and cheaper is recommended. In this sense, previous works [13][14][15][16] have shown that solid-liquid extraction with low temperature purification (SLE-LTP) has gathered these characteristics when applied to other environmental contaminants.…”

Fluopyram is a fungicide which can also be used as a nematicide in agricultural areas. The Brazilian Ministry of Agriculture authorized the commercialization and use of this molecule in Brazilian agriculture in 2019, but studies involving the development of an extraction and quantification method of this compound in environmental matrices such as soil are still scarce. Therefore, the present study aimed to optimize and validate the miniaturized version of the solid-liquid extraction with low temperature purification (SLE-LTP) method for determining this compound in sandy, clayey and medium-textured soil samples. All analyzes in this study were performed by gas chromatography coupled to mass spectrometry (GC-MS). The results revealed that the analyte recovery percentages in the three soil types ranged from 86 to 114% with a relative standard deviation of less than 15%. In addition to employing smaller amounts of reagents and sample, the miniaturized SLE-LTP method was selective, precise, exact, and linear in the range from 3 to 210 μg kg-1, and reached a limit of quantification lower than 3.00 μg kg-1 for the three soil types. The extraction method was applied to 30 real samples collected in coffee growing regions, but no residue of this compound was detected in these samples.

“…Hence, FPD and the residue of its toxicological metabolites in pepper should be stringently monitored for food safety. Currently, studies on FPD in China have been limited to the establishment of analytical methods in traditional Chinese herbal medicines, fruits, vegetables, and nuts (Fang et al, 2020; Li et al, 2016, 2018; Mahdavi et al, 2021). However, there is no information on FPD residues in pepper during cultivation or processing under field conditions.…”

An effective method based on LC-MS/MS was established to determine the concentrations of flupyradifurone, difluoroacetic acid, and 6-chloronicotinic acid in pepper. On the basis of this method, the dissipation, processing factor, and dietary risk of flupyradifurone in pepper were investigated. The results show that the half-life of flupyradifurone in peppers was 2.6-3.8 days. The terminal residual concentration of flupyradifurone in the supervised trials was not higher than the maximum residue limit (MRL) for pepper in the Codex Alimentarius Commission (CAC) (0.9 mg kg À1 ) with the highest residual values of 0.53 mg kg À1 . The national estimated daily intake of flupyradifurone was 0.00094 mg kg À1 , based on the dietary structure of Chinese consumers and the terminal residues under field conditions. The risk quotient for flupyradifurone was 0.012, which was significantly < 1. The processing factor of flupyradifurone in dried pepper was 10.9-14.2, which indicated that drying increased the residual amounts of flupyradifurone in dried pepper, but the residual concentration was still lower than its MRL of 9 mg kg À1 established by CAC.
