“…152 Quantification is performed using common analytical techniques GC-MS, HPLC, UHPLC-MS, or UHPLC-MS/MS and appropriate validation. 143,[153][154][155][156][157][158][159][160][161][162][163] Similar to other preparation methods, the original QuEChERS procedure was modified to improve the overall performance of the technique. The associated modifications involved the hydration of the samples and modification of the extraction and purification steps to improve the extraction efficiency and ability to eliminate interferences.…”

“…Based on this, miniaturization is one of the modifications that the QuEChERS procedure has experienced in the last years [15]. For instance, several authors have proposed its miniaturization for the determination of a wide variety of analytes in a broad range of matrices, such as for the simultaneous analysis of perchlorate and bromate in fruits and vegetables [57], the determination of antibiotics in human urine and serum [58], the determination of zearalenone in cereals [59], the multicomponent extraction of phenolic compounds in baby foods [60], the analysis of psychotropic drugs in blood and serum [61], the simultaneous determination of pesticides in human serum [62] and in odonata nymphs [63], and the extraction of bisphenol A from human urine samples [64]. Regarding PAs, two works have successfully proposed the miniaturization of the QuEChERS strategy in different aromatic herb samples, including oregano, thyme, rosemary, basil and herbs de Provence [27,28].…”

Application of the QuEChERS Strategy as a Useful Sample Preparation Tool for the Multiresidue Determination of Pyrrolizidine Alkaloids in Food and Feed Samples: A Critical Overview

The identification of concerning high levels of pyrrolizidine alkaloids (PAs) in a wide variety of food products has raised the occurrence of these natural toxins as one of the main current issues of the food safety field. Consequently, a regulation with maximum concentration levels of these alkaloids has recently been published to monitor their occurrence in several foodstuffs. According to legislation, the analytical methodologies developed for their determination must include multiresidue extractions with high selectivity and sensitivity, as a set of 21 + 14 PAs should be simultaneously monitored. However, the multiresidue extraction of these alkaloids is a difficult task due to the high complexity of food and feed samples. Accordingly, although solid-phase extraction is still the technique most widely used for sample preparation, the QuEChERS method can be a suitable alternative for the simultaneous determination of multiple analytes, providing green extraction and clean-up of samples in a quick and cost-effective way. Hence, this review proposes an overview about the QuEChERS concept and its evolution through different modifications that have broadened its applicability over time, focusing mainly on its application regarding the determination of PAs in food and feed, including the revision of published works within the last 11 years.

“…The original QuEChERS method requires 10 g of sample 14 , which is not always available for smaller sample sizes. Therefore, miniaturization of QuEChERS is an alternative technique for analyzing small samples 25 – 27 . In addition, the miniaturized method uses fewer reagents and solvents, is relatively cheaper, and reduces environmental impact compared to traditional methods 28 .…”

Habitat loss and fragmentation are among the greatest threats to biodiversity and ecosystem stability, with physiological implications on wild fauna. Bats (Microchiroptera) are small mammals with a wide variety of eating habits, and the well-being of these animals is disturbed by exposure to pesticides. This study aimed to develop a miniaturized QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extraction method for the detection of multi-residue pesticides in bat muscle tissue using gas chromatography coupled with mass spectrometry (GC–MS). A total of 48 pesticides were tested in 250 mg of bat muscle tissue. The developed analytical method was applied to 148 bats collected from two different areas in Minas Gerais State, Southeast Region of Brazil. The method presented good sensitivity and allowed the determination of residues of 48 pesticides in bat muscle using GC–MS. The miniaturized extraction method makes the analysis feasible even when the sample volume is limited. However, no pesticide residues were detected in bats from the two areas investigated.
