“…Individual certified standards of ARs and PhACs (purity 95.19% to 99.9%) were acquired from Dr. Ehrenstorfer (Augsburg, Germany), Sigma-Aldrich (Augsburg, Germany) and European Pharmacopoeia Reference Standards (Strasbourg, France). Atrazine-d5, Carbendazim-d3, Coumachlor, Cyromazine-d4, Linuron-d3 and Pirimicarb-d6 (Dr. Ehrenstorfer and Sigma-Aldrich, 99.3-99.9% purity) were used as procedural internal standards (P-IS) and were maintained as described in the reference method [41]. These internal standards were added to the samples at the beginning of the procedure to account for various sources of errors throughout all stages in the method [58].…”

“…The physicochemical properties of this composite are as follows: pH 4.88, electrical conductivity 209 µS cm −1 , oxidizable organic carbon 2.19% (approximately 3.9% organic matter), 6% moisture and particle size distribution: 29.5% clay, 28.3% fine silt, 11.3% thick slit, 11.5% coarse sand, and 19.4% fine sand. All these parameters were determined in the facilities of the Department of Department of Animal Biology, Edaphology and Geology of the University of La Laguna (Tenerife, Spain) [41].…”

“…The method used for the extraction of the target analytes was previously developed and validated in our laboratory for the extraction of pesticides in clay loam soil [41,60]. In summary, the samples were prepared by weighing 10 ± 0.05 g of dried and sieved soil into a 50 mL centrifuge.…”

“…ples and organic solvents, which has led to its use in different matrices and analytes [38]. Modified versions of QuEChERS have been successfully applied in soils for the extraction of organic contaminants, including pesticides [39][40][41], persistent organic pollutants [42,43], as well as in the extraction of ARs and PhACs from other samples such as food [44,45], blood [46,47], sediments and sludge [48], and the liver [49,50].…”

“…The objective of this research was to evaluate and validate a QuEChERS-based and LC-MS/MS method for the quantification of ARs and PhACs in soils, as well as their verification in samples of agricultural origin and from wildlife carcasses. The work is proposed as a scope extension of the previously optimized method for the quantification of pesticide residues in soils [41]. The proposed method can be applied in agricultural, environmental and forensic monitoring.…”

A modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) extraction was validated for the extraction of seven coumarin anticoagulant rodenticides (ARs) and 36 pharmaceutical active compounds (PhACs) residues in soil samples using liquid chromatography tandem mass spectrometry (LC-MS/MS). The aim of this work was to develop a method for the monitoring of these compounds in agricultural lands as well as in forensic applications for the determination of ARs poisoning. As far as is known, this is the first time that a QuEChERS-based method is used for the extraction of ARs in soil, as well as on such a quantity of PhACs. A matrix effect study was carried out on samples of soil devoted to agriculture in the midland area of the Canary Islands (clay loam type). It was in house validated (accuracy, precision, and linearity) at seven spiked levels between 0.5 and 50 ng g−1. The limits of quantification (LOQ) ranged between 0.5 and 50.0 ng g−1 and the limits of detection (LOD) ranged from 0.024 to 6.25 ng g−1. The method was then successfully used for both the determination of the target analytes in the soils from the agricultural plots that had been irrigated with regenerated water, and in the soil collected from underneath wild bird carcasses (which had been the subject of forensic investigation).

In multiresidue analysis, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) is one of the most popular techniques routinely used by researchers during pesticide analysis of food and vegetable samples. Originally, the QuEChERS method was developed for analysis of pesticide residues from fruits and vegetables, but rapidly gained popularity in the extraction of analytes from different matrices. This analytical approach shows several advantages over traditional extraction techniques: it requires lower sample and solvent amounts while shortening the time of sample preparation. However, it presents some limitations for complex matrices such as those containing high amounts of chlorophyll. To overcome the problem of strong matrix effect and influence of interferences, different approaches are applied. Most are concerning modifications of the cleanup step, that is, sorbent type and its amount. Optimization of other parameters, such as sample size, hydration level, extraction solvent, and buffering, also has an impact on overall performance. Combining proper sample preparation with modern highly sensitive and selective detection techniques enables receiving desired limits of quantification. This article presents an overview of strategies employed by researchers for analysis of green, high chlorophyll content commodities and results obtained in their studies.
