“…Short columns with the particle diameter not larger than 2 μm, first proposed by Waters in 2004 as BEH C 18 , with the particle diameter of 1.7 μm (Swartz 2005), are gaining increasing popularity. In this group of sorbents, the abovementioned column BEH C 1 8 (Sivaperumal et al 2015;Chung and Lam 2012;Chen et al 2011;Mastovska et al 2010) and Zorbax C 18 , with the particle diameter of 1.8 μm, from Agilent Technology (Perez-Ortega et al 2012;Stachniuk and Fornal 2013;Sinha et al 2012), are the most popular in the analysis of pesticide residues in food. Reduced particle diameter necessitates the use of increasingly higher pressures.…”

“…Its sample purity requirements are not stringent, and it enables a simultaneous analysis of substances that vary considerably in polarity. The popularity of the method is confirmed by the increasing number of publications dedicated to the applications of LC-MS in the determination of contaminants, including pesticides, in food (Sivaperumal et al 2015;Gómez-Pérez et al 2015;Martinez-Dominguez et al 2015;Golge and Kebak 2015;Fillatre et al 2014;Esturk et al 2014;Oshita and Jardim 2014;González-Curbelo et al 2014;Rajski et al 2013;Arienzo et al 2013;Stachniuk and Fornal 2013;Sinha et al 2012;Gilbert-Lopez et al 2012;Lozano et al 2012;Chung and Lam 2012;BoteroCoy et al 2012;Tian 2011;Pareja et al 2011;Kmellar et al 2011;Aguilera-Luiz et al 2011;Chen et al 2011;Lehotay et al 2010;Zhang et al 2010;Camino-Sanchez et al 2010;Kamel et al 2010;Brutti et al 2010). In pesticide residue analysis, similarly to the analysis of other food contaminants, there is a distinct tendency to develop fast multiresidue methods.…”

Liquid Chromatography-Mass Spectrometry in the Analysis of Pesticide Residues in Food

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.

Pesticide residues in tea is a major issue due to their widely used in tea cultivation. Thus, to protect consumers, an appropriate method for determination of their residues in tea should be done. In this study, a method for the simultaneous determination of 51 pesticides in tea was developed and validated. The tea sample was extracted by acetonitrile and purified SPE clearnet TPT column followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) with multi-reaction monitoring (MRM) mode. The method was validated according to the linearity, limit of detention, precision, the percentage of recovery at three different spike levels. The linear concentration range used was 10-100ng/ mL, the square of Correlation coefficient r 2 was more than >0.995. Recoveries were adequate being in the acceptable range of 72-89% and RSD of <19 % for all the analytes at three level of 0.01,0.05 and 0.11mg/kg, the LOD of all chemicals from 0.001 mg/kg to 0.01 mg/kg .The method was applied for the determination for 400 tea samples collected from Pu'er which contain green tea and black tea. Among the analyzed samples , 36 % samples had Imidacloprid and 25% sample contain Acetamiprid, which were at a level below the European Union maximum residue levels (EU-MRLs). The information would be beneficial for Pu'er tea exporters.

Fast Determination of Pyrethroid Pesticides in Tobacco by GC-MS-SIM Coupled with Modified QuEChERS Sample Preparation Procedure

et al. 2013

An analytical method was developed for the extraction and determination of pyrethroid pesticide residues in tobacco. The modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method was applied for preparing samples. In this study, methyl cyanide (MeCN)-saturated salt aqueous was used as the two-phase extraction solvent for the first time, and a vortex shaker was used for the simultaneous shaking and concentration of the analytes. The effects of experimental parameters on extraction and clean-up efficiency were investigated and optimized. The analytes were determined by gas chromatography-mass spectrometry-selected ion monitoring (GC-MS-SIM). The obtained recoveries of the analytes at three different fortification levels were 76.85 -114.1% and relative standard deviations (RSDs) were lower than 15.7%. The limits of quantification (LOQs) were from 1.28 to 26.6 μg kg -1 . This method was also applied to the analysis of actual commercial tobacco products and the analytical results were satisfactory.
