“…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.

“…Acetato de etila tem demonstrado ser um solvente com características universais, uma vez que possui capacidade para extrair pesticidas de diferentes classes em diversos tipos de amostras, porém os percentuais de recuperação de pesticidas com caráter básico (pKa > 4) são baixos devido a problemas de degradação, sendo necessária a adição de hidróxido de sódio para um aumento destes percentuais. 42 Acetona e acetonitrila são miscíveis com água e promovem a extração em uma fase única quando em contato com a matriz. Quando uma extração é realizada com acetona há necessidade de adição de solventes apolares para que ocorra a separação entre as fases orgânica e aquosa, o mesmo não é necessário quando se utiliza acetonitrila, uma vez que a adição de sais ao extrato faz com que ocorra tal separação.…”

. This review attempts to provide an updated overview of the Quick, Easy, Cheap, Effective, Ruged and Safe (QuEChERS) multiresidue extraction method, that involves initial extraction in acetonitrile, an extraction/partition step after the addition of salt, and a cleanup step utilizing dispersive solid phase extraction. QuEChERS method is nowadays the most applied extraction method for the determination of pesticide residues in food samples, providing acceptable recoveries for acidic, neutral and basic pesticides. Several applications for various food matrices (fruits, vegetables, cereals and others) in combination with chromatographic mass spectrometry analysis were presented.Keywords: QuEChERS method; food analysis; pesticides. INTRODUÇÃONo mundo, as perdas anuais devido à ação de pragas na agricultura chegam a 1 bilhão de toneladas, correspondendo a uma redução de 20 a 30% na produção. Os pesticidas, desde seu desenvolvimento, desempenharam um importante papel no crescimento da agricultura moderna. A utilização destes compostos químicos, que por um lado gera benefícios, por outro, é responsável pela contaminação do solo, água e alimentos.1 Assim, a determinação de resíduos de pesticidas em alimentos e em amostras ambientais é importante devido ao risco que estes compostos oferecem à saúde humana, além da sua persistência no meio ambiente e tendência de bioacumulação. Nas últimas décadas, laboratórios públicos e privados vêm desenvolvendo métodos para a determinação de resíduos de pesticidas, principalmente em alimentos. Contudo, a maioria dos métodos oficiais de análise está longe do considerado ideal, ou seja, métodos de ampla aplicação, rápidos, sensíveis e com resultados confiáveis. 2 A determinação de resíduos de pesticidas desempenha um papel importante para a estimativa da exposição humana e do meio ambiente a estes compostos, permitindo avaliar a conformidade da produção agrícola com as Boas Práticas Agrícolas, possibilitando decisões regulatórias comerciais visando garantir a segurança alimentar. Atualmente, ações governamentais e também do setor privado, estabelecem uma maior importância para a análise de resíduos de pesticidas, sendo que há uma pressão crescente para o aperfeiçoamento do desempenho analítico, exigindo aumento da eficiência e diminuição do custo e do tempo das análises. Produtos agrícolas como frutas, vegetais e cereais são as matrizes mais analisadas em laboratórios de rotina, apresentando frequentemente resíduos de pesticidas de diversas classes. Assim, é de fundamental importância o desenvolvimento de métodos multirresíduo de pesticidas para a determinação nestes tipos de alimentos. A diferença das propriedades químicas entre estes compostos e a diversidade de matrizes são algumas das adversidades a serem contornadas no desenvolvimento destes métodos, os quais frequentemente apresentam etapas laboriosas que demandam tempo, grande custo de material e geram grandes quantidades de resíduos tóxicos. 5 as modificações do procedimento original descritas na literatura e as aplicações dest...

Dissipation and leaching studies of cyazofamid in two texturally different soils of Tarai region of India at two fortification levels (100 and 200 g a.i. ha -1 ) were carried out for monitoring residual toxicity and groundwater contamination. Soil was extracted with acetone : methanol (5:1 v/v) followed by cleanup with florisil SPE. Separation was achieved by RP-HPLC on a Discovery Ò C-18 column using mobile phase acetonitrile: water (60:40 v/v) and detection at 279 nm. Degradation pattern indicated correspondence to monophasic first-order kinetics in soils with half-life values ranging from 4.3 to 4.95 days. The degradation rate was slight different in both types of soils. Persistence was higher in sandy loam compared to silty clay loam soil. Linearity, R 2 of calibration curve, instrument limit of detection/quantitation (LOD/LOQ) was evaluated. Good linearity (R 2 = 0.99) of the calibration curves for quantification was obtained over the dynamic range of 0.1-10.0 lg mL -1 , and percent relative standard deviation was 1.72 %. Leaching experiment showed that cyazofamid could not leached beyond 15 cm of soil depth. Maximum concentration was at 5-10 and 10-15 cm soil depth. Average recoveries from soils fortified at 0.5-5.0 lg g -1 ranged from 78 to 86 %. Instrument LOD values were 0.01 lg mL -1 , and method LOQ values were 0.05 lg g -1 . A fast, easy and efficient method with acceptable performance was achieved. Results showed that cyazofamid has a short life in soils and low potential to leach down under heavy rainfall conditions. Results confirm that cyazofamid would not build up in the environment and have less possibility of groundwater contamination.
