“…The QuEChERS ''Quick, Easy Cheap, Effective Rugged and Safe''method is employed frequently as a sample preparation methodology for multi-residue pesticide analysis and has been modified and validated for the detection of a broad range of pesticides in food، including highly polar pesticides, and highly acidic and basic ones (Anastassiades et al 2003;Lehotay et al, 2010;Park et al, 2011;Payá et al, 2007). This method involves extraction with acetonitrile and partitioning after the addition of a salt mixture.…”

Thiophanate-methyl is an effective fungicide on several food crops. In the present study, dissipation of residue levels of thiophanate-methyl in apple and strawberry fruits under open field conditions were studied using high performance liquid chromatography with diode array detection (HPLC-DAD).The extraction and clean-up were conducted by QuEChERS method. The limit of quantitation and detection were 0.01 and 0.003 mg/kg, respectively. The results suggest that the thiophanatemethyl dissipation curves followed the first order kinetics and its half-life values were (1.01) and (1.26) days for apple and strawberry, respectively. The residues in apple and strawberry were below the codex maximum residue limit (MRL) (0.5 and 0.1 mg/kg) after 8 and 4 days of the application, respectively.

“…QuEChERS combined with fast GC becomes a good choice to speed up multiresidue analysis. Although this procedure has been implemented for a wide range of commodities, especially fruits and vegetables in many routine laboratories with satisfactory results (Cieślik et al 2011;Dai et al 2011;Jiang et al 2009;Kolberg et al 2011;Park et al 2011;Cherta et al 2012a), only few publications have been reported for the analysis of juice samples, especially using GC or fast GC. The original QuEChERS version has been applied for the determination of 118 pesticides in vegetable juice by GC-MS and liquid chromatography-tandem mass spectrometry (Nguyen et al 2009).…”

Comparison of Simple and Rapid Extraction Procedures for the Determination of Pesticide Residues in Fruit Juices by Fast Gas Chromatography–Mass Spectrometry

Three sample treatment methods, based on QuEChERS, solid-phase extraction (SPE) and solid-phase microextraction (SPME), were compared and evaluated in order to obtain the best conditions to determine pesticide residues in fruit juice by fast gas chromatography-mass spectrometry (single quadrupole GC-MS). Analysis were performed under selected ion monitoring, acquiring the three most abundant and/or specific ions for each analyte and using their relative intensity ratios as a confirmatory parameter. The 3 methodologies (QuEChERS, SPE and SPME) were validated taking 15 selected pesticides as model compounds, using commercial apple juice. QuEChERS procedure was based on the AOAC Official Method 2007.01, using acetonitrile (containing 1 % acetic acid) as extraction solvent and primary-secondary amine during the dispersive solid-phase extraction. Oasis hydrophilic-lipophilic balance cartridges were used for SPE, and polyacrylate fibers were used for direct immersion SPME procedure. Three isotopically labeled standards were added to the samples before extraction and used as surrogate standards. Validation parameters as recoveries, limits of detection, and limits of quantification (LOQ), as well as matrix effects and sample throughput, were obtained and compared for the three extraction procedures. QuEChERS was considered faster and led to the best quantitative results.In this way, validation was extended to up to 56 pesticides by applying QuEChERS in multi-fruit juice samples, obtaining LOQs ranging from 2 to 20 µg/L for most 2 compounds. Accuracy and precision were evaluated by means of recovery experiments at two concentration levels (10 and 100 µg/L), obtaining recoveries between 70 and 120 % in most cases and relative standard deviations below 15 %.Finally, the QuEChERS method was applied to the analysis of commercial juices, including mango-apple, pineapple, grapefruit and orange.

“…Public attention has focused on estimating the level of exposure at the point of consumption after processing (Ling et al, 2011). Cooking might alter and degrade the chemical structure of the analytes and might change the matrix in food as well (Park et al, 2011). Therefore, to evaluate the hazardous effects of pesticides on human health, raw and cooked foodstuffs appear to be a more reasonable sample choice (Park et al, 2011).…”
