“…It has a number of inherent properties that are advantageous for this application, including high selectivity and sensitivity, minimization of sample cleanup steps, and easy and reliable identification and quantification of pesticide residues at even very low levels (Picó et al, 2006). A number of multiresidue methods using LC-MS/MS for residue determination have been reported (Jansson et al, 2004;Ortelli et al, 2004;Cavaliere et al, 2005;Sancho et al, 2005;Hernández et al, 2006;Chen and Chen, 2007;Mertz et al, 2007;Sannino, 2007).…”

Liquid chromatography in conjunction with tandem mass spectrometry was used to directly quantify of 47 pesticide residues from cooked wheat flour and polished rice, which are the most widely consumed cereals in the Republic of Korea. The sample clean-up was carried out according to the method established by the Korea Food and Drug Administration. The mobile phase for liquid chromatograpy separation consisted of water and 5 mM methanolic ammonium formate. Tandem mass spectroscopy experiments were performed in electrospray ionization positive mode and the multiple reaction monitoring mode. The matrix effects estimated for the 47 pesticides had a mean value of 99% and ranged from 45 to 147%. High recoveries (70-140%) and relative standard deviations (£20%) were achieved for most of the pesticides tested. The method used in this study allowed for rapid quantification and identification of low levels of pesticides in cooked wheat flour and polished rice samples. Of the screened pesticide residues, only tricyclazole and fenobucarb were found in polished rice samples. However, no samples contained residues above the MRL established by the Korea Food and Drug Administration.

“…Liquid chromatography (LC) coupled with tandem mass spectrometry (MS/MS) is one of the most powerful techniques for pesticide residue analysis in fruits and vegetables. This technique provides excellent sensitivity/selectivity and discriminates analyte and matrix signal more efficiently than GC-MS (Alder et al 2006) or LC-MS (Hernandez et al 2006). In recent years, a number of reliable LC-MS/MS methods have been developed for pesticide residue analysis for the postharvest fungicide residues (thiabendazole, carbendazim, thiophanate-methyl, imazalil and prochloraz) in citrus juices (Dreassi et al 2010), for guazatine in commercial citrus fruits (Scordino et al 2008), for thiosultap sodium, thiocyclam, and nereistoxin in pepper (Ferrer et al 2010), for multi-class pesticides residues in fresh grape samples (Venkateswarlu et al 2007) and in olives (Ferrer et al 2005).…”

In this study, pesticide residues in parsley, lettuce and spinach (120 samples) were analyzed by the application of liquid chromatography-tandem mass spectrometry (LC-MS/MS). All samples of spinach, parsley or lettuce contained residues of three or more active substances. In parsley, carbendazim (100.0%), dichlorvos (100.0%), fenarimol (40.0%), pendimethalin (95.0%), in lettuce, diazinon (30.0%), dichlorvos (100.0%), pendimethalin (92.5%) phenthoate (12.5%), and in spinach, carbendazim (45.0%), cymoxanil (85.0%), dichlorvos (100.0%) and fenarimol (85.0%) were the significant active compounds. The maximum residue limits were exceeded in 28, 20 and 40 samples of parsley, lettuce and spinach, respectively. The results showed that there was a high occurrence of pesticide residues in parsley, lettuce and spinach samples from Hatay province, in which most of them were prohibited from use in Turkey for these vegetables. The contamination levels of these residues may be considered a serious public health problem according to the maximum residue limits (MRLs) of Turkey and the European Union (EU).

“…For this purpose, some of the most popular extraction procedures are based on solvent extraction by shaking or mechanical stirring [12,14], in a Soxhlet apparatus, or with ultrasound sources [13,22]. Traditional solvent extraction methods may be sometimes inefficient and may require long extraction times and large quantities of organic solvents.…”

In the present work we address the development of a simple and effective method for the determination of triazine herbicide residues in horticultural products by CE in nonaqueous media (NACE). Potato samples were selected as a representative matrix of such foods with a nonfatty content. Isolation of the analytes from the sample matrix was accomplished by extraction with organic solvents, assisted by ultrasound; a clean-up step of the organic extracts was carried out with SPE, using an Oasis MCXm sorbent to retain the analytes directly from the organic medium. The detection limits achieved in spiked potatoes (1.7 -4.0 lg/kg) were lower than the default value of maximum residue level (MRL) established by current EU legislation for pesticide residues in foodstuffs. The results obtained were compared with HPLC in order to evaluate the performance of the NACE procedure.
