“…Among these methods, SPE and d-SPE are widely used purification methods. However, most of the reported methods regarding multiclass pesticide residues in fish have focused on modification of the QuEChERS method in recent years. − In this study, the combination of SPE and d-SPE in the purification step gave satisfactory precisions and recoveries and showed a lower LOQ in comparison to previous methods, which can be used to effectively monitor pesticide residues in fish at trace levels.…”

“…A traditional QuEChERS method based on d-SPE cleanup, as mentioned earlier for low-fat foods, was evaluated for its suitability for the purification of fish matrix. ,, The most commonly used sorbents for fish purification are PSA and C18, according to an analysis of the previous literature. , The role of PSA is to remove fatty acids, sugars, and other matrix coextractives, while the role of C18 is to remove the remaining lipids …”

“…2 Fish samples are relatively complex matrices with a high protein and lipid content. 9,10 During extraction, the proteins can be removed by precipitation and centrifugation. However, a large amount of fatty acids, triglycerides, and cholesterol are extracted along with the target compounds, 11 and these coextracts have many adverse effects on the chromatographic column and apparatus and produce a strong matrix effect affecting the test results.…”

A robust isotope-labeled internal standard method was established for the detection of 22 pesticides and metabolite residues in four kinds of fish; two were from freshwater fish, and two were from marine fish. Pesticides with wide application possibilities in rice in China, strong leaching to water, or high bioconcentration factors (BCF) in fish were selected. The samples were extracted with 1% acetic acid−99% acetonitrile. The extracts were first purified by solid-phase extraction (PEP-plus), cleaned with dispersive-solid-phase extraction (PSA and C18), and finally analyzed by liquid chromatography−tandem mass spectrometry (LC-MS/MS). The results showed that good linearities for the target compounds were observed in the range of 0.1−100 ng/mL, and the correlation coefficient (R 2 ) of each compound was greater than 0.99. The recoveries of the method were within 70−120% with RSDs <20% at three different spiked concentration levels (0.5, 5, and 100 ng/g). The quantitative limit of the method was 0.5− 5 ng/g. The method is shown to be sensitive and accurate and can meet the demands for the quantitative analysis of pesticides in fish.

“…Both strategies are commonly applied for either LC-MS [25,128] or GC-MS methods [129,130]. It should be noted that although only one or a few IL-ISs are selected for the IL-IS approach, the quantitative performance of multiresidue methods increases when multiple IL-ISs covering different families of pesticides are used [131,132]. Other strategies to reduce the matrix effect include the possibility of applying standard addition or procedural calibration; however, matrix-matched calibration is still the preferred approach according to SANTE/2020/12830 [14].…”

The extensive use of pesticides represents a risk to human health. Consequently, legal frameworks have been established to ensure food safety, including control programs for pesticide residues. In this context, the performance of analytical methods acquires special relevance. Such methods are expected to be able to determine the largest number of compounds at trace concentration levels in complex food matrices, which represents a great analytical challenge. Technical advances in mass spectrometry (MS) have led to the development of more efficient analytical methods for the determination of pesticides. This review provides an overview of current analytical strategies applied in pesticide analysis, with a special focus on MS methods. Current targeted MS methods allow the simultaneous determination of hundreds of pesticides, whereas non-targeted MS methods are now applicable to the identification of pesticide metabolites and transformation products. New trends in pesticide analysis are also presented, including approaches for the simultaneous determination of pesticide residues and other food contaminants (i.e., mega-methods), or the recent application of techniques such as ion mobility–mass spectrometry (IM–MS) for this purpose.
