“…Common dSPE sorbents include C18 or C8 for removal of lipids; florisil for removal of polar and low-fat co-extracts; graphitized carbon black (GCB) for removal of pigments and some fatty acids; primary secondary amine (PSA) for efficient removal of saccharides and organic acid as it is a weak anion exchanger; and Z-Sep (ZrO 2 bonded to silica) or Z-Sep+ (ZrO 2 and C18 both bonded to silica) for removal of lipids [15]. PSA has been reported to remove butanoic acid, decanoic acid, heptanoic acid, hexanoic acid, linoleic acid, and phytosterol (stigmasterol), while not effectively removing alkaloids (caffeine and theobromine) and γ-tocopherol [30]. The use of GCB with PSA, C18, and anhydrous MgSO 4 was found to improve recoveries for OPs and carbamates in egg matrix as compared to when GCB was not used [31].…”

“…For food commodities, the recoveries of analytes analyzed by LC-MS/MS (OPs, azoles, sulfonylureas) increased with dSPE following the salt-out acetonitrile extraction, while for analytes (OCs, OPs, pyrethroids) analyzed by GC-MS/MS, recoveries often decrease into an acceptable range of 70-120% [30]. PSA can bind some analytes strongly such as cinosulfuron that observed 20% decrease in recoveries [30].…”

“…PSA can bind some analytes strongly such as cinosulfuron that observed 20% decrease in recoveries [30]. Some OPs may exhibit better recoveries with GC-MS/MS rather than LC-MS/MS methods as observed for acephate and methidathion [30]. GCamenable pesticides tend to include the more lipophilic pesticides, particularly OCs and pyrethroids that have a higher tendency to be extracted with the fatty acid matrix components.…”

This chapter focuses on sample preparation procedures for pesticide analysis of food commodities, biological and environmental matrices. This will include pesticides with a broad range of polarity including those that are more amenable to gas chromatographymass spectrometry (organochlorines, organophosphorus pesticides, and pyrethroids) and those commonly analyzed by liquid chromatography-mass spectrometry (carbamates, azole, and strobilurin fungicides, and phenylureas as well as organophosphorus pesticides). QuEChERS (quick, easy, cheap, effective, rugged, and safe) methods or QuEChERS methods with modifications to allow wetting of the dry sample matrix, buffering, changing extraction solvent from acetonitrile to ethyl acetate are examined. Subsequent cleanup using dispersive solid phase extraction or cartridge format solid phase extraction has also been completed to reduce matrix effects. Other solid matrices are frequently extracted with pressurized liquid extraction, microwave assisted extraction, or ultrasonic extraction combined with or followed by dispersive solid phase extraction or solid phase extraction. Particularly for chromatography-mass spectrometry, careful consideration of matrix effects needs to be made when considering the design of the sample preparation procedures. Selection of extraction solvent needs to consider both polarity of target analytes (and their solubility in selected solvents) as well as co-extracted matrix components.

“…In the analysis of pesticide residues in food, the quadrupole-linear ion trap tandem mass spectrometer has been used mainly to analyze pesticide residues in vegetables and fruit (Sinha et al 2012;Afify et al 2010;Lee et al 2009a, b;Pihlstrom et al 2007;Banerjee et al 2007), (Lee et al 2009a, b), cocoa beans (Zainudin et al 2015), lavandin oil (Fillatre et al 2014) fruit beverages (Tran et al 2012;Ferrer et al 2011), and fish muscle (Lazartigues et al 2011). …”

The analysis of pesticide residues in food is nowadays an increasingly important task. Quality control has to be very strict in order to safeguard the consumers' health. One of the most important goals of food quality assurance is testing food for residues and contaminants. Among chemical hazards, the contamination of food with pesticides has been characterized as a significant source of many serious diseases. Consumption of food containing pesticide residues may cause cancer, malformations, and damage to the endocrine, nervous, and immune system. In order to assure human food safety, The European Community has established maximum residue limits (MRL) of pesticides permitted in products of animal or vegetable origin that are intended for human consumption. In the EU, Regulation (EC) No. 396/2005 of the European Parliament and Council on pesticide residues established the levels of pesticide residues allowed in food and feed. To ensure the compliance of marketed food commodities with the law on food safety, sensitive and reliable analytical methods for the determination of pesticide residues are required. Multiresidue liquid chromatography-mass spectrometry methods (LC-MS) are widely recognized as an ideal, highly specific, and extremely sensitive technique for testing food products. This review discusses LC-MS approaches applied most widely to pesticide residue analysis over the last few years. The main ionization methods and MS detectors used as analytical tools in quantification and/or identification/confirmation of pesticide residues in food are presented.

A sensitive electrochemical method for square-wave voltammetric detection of organophosphate (OP) compounds was developed based on zirconia (ZrO 2 ) nanoparticles modified electrode. The electrode was fabricated using electrochemical deposition and characterized by scanning electron microscopy (SEM), which confirmed the successful formation of nanoparticles. Due to the strong affinity of ZrO 2 with the phosphoric group, OPs can strongly bind to the surface of ZrO 2 nanoparticles (ZrO 2 NPs). Under optimized operational conditions, SWV was employed for Omethoate (a model of OP compounds) detection with 5 min absorption, which showed a wide detection range from 98.5 pmol•L −1 to 985 nmol•L −1 , with a detection limit as low as 52.5 pmol•L −1 . This electrochemical sensor has good selectivity, stability and reproducibility, and great potential in the detection of OP compounds in agriculture area.
