“…A molecularly imprinted fiber (synthesized using atrazine as template) has been applied for the SPME preconcentration and subsequent analysis of triazines by GC-MS in water and food samples (Djozan & Ebrahimi, 2008). Stir bar sorptive extraction (SBSE) was developed to overcome the limited extraction capacity of SPME fibers and has been used for the determination of different classes of pesticides by GC-MS and LC-MS (Ochiai et al, 2005(Ochiai et al, , 2006Bonet-Domingo et al, 2007;Giordano et al, 2009;Sanchez-Ortega et al, 2009) (Tables 1 and 2). Hollow-fiber liquid-phase microextraction (HF-LPME) is another version of SPME of interest to LC-MS analysis; it differs from the latter in that the solid fiber is replaced by a porous (hollow) polypropylene fiber coated with an organic liquid stationary phase (RomeroGonzález et al, 2006;Plaza Bolãnos et al, 2008).…”

Analysis of pesticides and their metabolites in food and water matrices continues to be an active research area closely related to food safety and environmental issues. This review discusses the most widely applied mass spectrometric (MS) approaches to pesticide residues analysis over the last few years. The main techniques for sample preparation remain solvent extraction and solid-phase extraction. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) approach is being increasingly used for the development of multi-class pesticide residues methods in various sample matrices. MS detectors-triple quadrupole (QqQ), ion-trap (IT), quadrupole linear ion trap (QqLIT), time-of-flight (TOF), and quadrupole time-of-flight (QqTOF)-have been established as powerful analytical tools sharing a primary role in the detection/quantification and/or identification/confirmation of pesticides and their metabolites. Recent developments in analytical instrumentation have enabled coupling of ultra-performance liquid chromatography (UPLC) and fast gas chromatography (GC) with MS detectors, and faster analysis for a greater number of pesticides. The newly developed "ambient-ionization" MS techniques (e.g., desorption electrospray ionization, DESI, and direct analysis in real time, DART) hyphenated with high-resolution MS platforms without liquid chromatography separation, and sometimes with minimum pre-treatment, have shown potential for pesticide residue screening. The recently introduced Orbitrap mass spectrometers can provide high resolving power and mass accuracy, to tackle complex analytical problems involved in pesticide residue analysis.

“…Generally speaking, the determination of routine pesticide multi-residues in tea, water or other food samples is usually carried out by GC in combination with electron capture detection [2,3], flame photometric detection [4], MS [5 -7] and MS/MS [8,9]. These methods are suitable for analysis of thermally stable, low-polar and volatile pesticides.…”

A simple and sensitive method was developed and validated for the simultaneous determination of 103 pesticide residues in tea by LC-MS/MS. For the analysis of the pesticide with polarity, thermal lability or low volatility, this LC-MS/MS method has an advantage over GC. In this work, residual pesticides were extracted from the tea sample with ACN and then purified using Carb-NH 2 SPE cartridges. Using the multiple reaction monitoring mode, the pesticides were quantified and identified by the most abundant and characteristic fragment ions. The recoveries obtained for each pesticide ranged between 65 and 114% at three spiked concentration levels. The intra-day precisions were lower than 19.6%. Good linear relationships were observed with the correlation coefficients r 2 A0.996 for all analytes. The established method was successfully applied to the determination of pesticide residues in real tea samples.

“…Solid-phase microextraction (SPME) has also been studied for pesticide analysis in honey [2,12] but showed sample input limitations and relatively high limit of detection [11]. Supercritical fluid extraction (SEE) and stir-bar sorptive extraction (SBSE) still remain quite marginal in this area until now [5,13]. In this study, an on-column liquid-liquid extraction (OCLLE) method has been tested as it seemed to combine advantages of LLE, SPE and SPME.…”

We report on the development and validation under ISO 17025 criteria of a multi-residue confirmatory method to identify and quantify 17 widely chemically different pesticides (insecticides: Carbofuran, Methiocarb, Pirimicarb, Dimethoate, Fipronil, Imidacloprid; herbicides: Amidosulfuron, Rimsulfuron, Atrazine, Simazine, Chloroturon, Linuron, Isoxaflutole, Metosulam; fungicides: Diethofencarb) and 2 metabolites (Methiocarb sulfoxide and 2-Hydroxytertbutylazine) in honey. This method is based on an on-column liquid-liquid extraction (OCLLE) using diatomaceous earth as inert solid support and liquid chromatography (LC) coupled to mass spectrometry (MS) operating in tandem mode (MS/MS). Method specificity is ensured by checking retention time and theoretical ratio between two transitions from a single precursor ion. Linearity is demonstrated all along the range of concentration that was investigated, from 0.1 to 20 ngg -1 raw honey, with correlation coefficients ranging from 0.921 to 0.999, depending on chemicals. Recovery rates obtained on home-made quality control samples are between 71 and 90%, well above the range defined by the EC/657/2002 document, but in the range we had fixed to ensure proper quantification, as levels found in real samples could not be corrected for recovery rates. Reproducibility is found to be between 8 and 27%. Calculated CCα and CCβ (0.0002-0.943 ngg -1 for CCα, and 0.0002-1.232 ngg -1 for CCβ) show the good sensitivity attained by this multi-residue analytical method. The robustness of the method has been tested in analyzing more than 100 raw honey samples collected from different areas in Belgium, as well as some wax and bee samples, with a slightly adapted procedure.
