“…Thermal treatments presented in the literature are characterized by different efficiencies, from the elimination of entire residues to no influence on the residue levels, while our results indicated that cyflumetofen residues were decreased during the blanching process, which was presumably because the high temperatures increased the volatilization or degradation of cyflumetofen (Han et al, 2016). This finding is in accordance with several previous studies that demonstrated that thermal processing reduced most pesticide residues within the range of 19% to 87% in broccoli, from 43% to 93% in strawberries, and up to 98% in blackcurrants (Jankowska et al, 2019).…”

“…This result is similar to other studies, where the quantity of residue removed by peeling was in the range of 60 to 100% in agricultural commodities (Cengiz, Certel, Karakaş, & Göçmen, 2007). Jankowska et al (2019) found that the removal of the tomato peel lowered fungicide concentrations by 68% to 87%, and the pesticide residues in squeezed blackcurrants were decreased by over half when compared with the content in the raw material. Further, the results showed that peeling is more effective than washing for removal of cyflumetofen residues because the washing stage could only remove the pesticide content that is in close contact with the skin, while peeling eliminates any pesticide that has permeated the apple epidermis (Rawn et al, 2008).…”

“…Fruits and vegetables vary in morphology, mass, size, chemical composition, among other qualities, which may play an essential role in the distribution and position of pesticides in the plant. Phospholipid bilayers contain hydrophilic groups that show affinity for polar pesticides but hydrophobicity towards non-polar pesticides (Jankowska, Łozowicka, & Kaczyński, 2019). Third, the technological conditions of food processes also influence PF values.…”

The effect of food processing on the level and fate of chiral pesticide residues in apple products has rarely been investigated. In this study, we used ultra-performance convergence chromatography coupled with triple quadrupole mass spectrometry to determine the content of the novel chiral acaricide cyflumetofen. The matrixmatched calibration lines were constructed for apple slices, juice, wine and vinegar, and the determination coefficients (r 2) exceeded 0.9954. Acceptable average recoveries were within 81.1% to 119.9%, and the relative standard deviations (RSDs) ranged from 0.8% to 11.0%. Processing effectiveness is represented by the processing factor (PF). The results indicated that the PFs of different procedures (washing, peeling, enzymolysis, fermentation, among others.) were generally less than 1. The reduction of cyflumetofen enantiomers during fermentation was in accordance with first-order kinetics, and stereoselective behavior was observed. This study provides reliable references for the risk assessment of cyflumetofen in the processing of apple products.

Вивчення питання щодо формування висоти, приросту пагонів та об'єму куща рослин смородини залежно від елементів агротехнології. Методи. Польовий, фізичний, аналітичний, статистичний. Результати. З'ясовано, що висота рослин, приріст пагонів і об'єм куща смородини істотно змінюються залежно від елементів агротехнології та погодних умов. Найвищими рослини смородини були за утримання міжрядь під чистим паром і мульчування прикущових смуг соломою, яка зростала з 1,15 м у варіанті без добрив до 1,36 м у варіанті фон + Ріверм 3 % або на 18 %. Залуження міжрядь насаджень смородини істотно знижувало висоту рослин. Проте описана тенденція впливу мульчування та удобрення на цей показник була подібною. Найбільший вплив на висоту рослин під час застосування добрив встановлено за утримування прикущових смуг мульчуванням плівкою. Так, висота зростала з 0,75 м у варіанті без добрив до 1,10-за внесення N60P90K90 і до 1,21 м-у варіанті фон + Ріверм 3 %. Оптимальний приріст пагонів смородини забезпечує мульчування прикущових смуг соломою на фоні повного мінерального добрива з позакореневим підживленням добривом Ріверм 3 % за утримання міжрядь під чистим паром. Висновки. Висота рослин, приріст пагонів і об'єм куща смородини істотно змінюються залежно від елементів агротехнології та погодних умов. Утримання ґрунту в міжряддях найбільше впливає на приріст пагонів рослин смородини чорної. За утримання ґрунту під чистим паром приріст пагонів становить 7,5-24,0 м, висота-1,08-1,29 м, об'єм куща-0,85-1,22 м 3 залежно від застосування добрив. За умови залуження параметри куща смородини становлять відповідно 6,0-15,2 м, 0,76-1,22 м, 0,65-0,99 м 3. Застосування добрив дозволяє збільшити приріст пагонів на 16,5 м за утримання ґрунту в міжрядді під чистим паром і на 9,2 м-за умови залуження. В агротехнології смородини чорної оптимально міжряддя утримувати під чистим паром із застосуванням N60P90K90 + Ріверм 3 %. Ключові слова: смородина; висота; приріст пагонів; об'єм куща.

“…In this study, three protein removal reagents as purification reagents and four volume ratios of serum-topurification reagent were tested for optimizing the extraction method and improving the detection of residues of multi-classes pesticides. Also 34 pesticides were selected from nine representative groups of chemicals, namely carbamate, imidazolinone, neonicotinoid, organophosphate, triazine, triazole, urea, strobilurin, and aryloxyalkanoic (Supporting Information Table S1), which were frequently present in food [3,[32][33][34][35][36][37], and compared the recoveries and detection limits of these pesticides in human serum. This efficient residue analysis method could be used to improve limits of detection for multi-classes pesticides in human serum.…”

Detecting pesticide residues in human serum is a challenging process. In this study we developed and validated a method for the extraction and recovery of residues of multiple classes of pesticides from serum using one reagent. Salt‐assisted acetonitrile extraction and high‐performance liquid chromatography with quadrupole time of flight tandem mass spectrometry were used to quantitate 34 pesticides classified in nine groups of chemicals in human serum samples, which are frequently detected in food. The recoveries for 33 of analyzed pesticides ranged from 86 to 112% with relative standard deviations below 15%. The limits of quantitation and linearity of 31 of the pesticides were 1 µg/L and >0.990, respectively. The lower limit of quantitation has been reported in the literature particularly for multi‐classes pesticide mixtures in human serum. The salt–acetonitrile reagent was allowed to achieve good recoveries and detection limits, which could be attributed to salt altering the solvent polarity, preferentially collecting the organic phase in the solution, and promoting the extraction. The developed method was applied for two organophosphate pesticide metabolites, diethylphosphate and 3,5,6‐trichloro‐2‐pyridinol, in serum from rats that were fed a nonlethal quantity of chlorpyrifos. The concentrations of these two were 252.18 ± 15.47 and 0.63 ± 0.23 µg/L, respectively.
