“…Considering the fact that fruit juices are becoming more and more popular, it is necessary to develop sensitive and selective methods for the analysis of triazole fungicide residues usually present in trace amounts. Many chromatographic analytical methods for the trace determination of triazole fungicide residues in water and fruit juice samples included gas chromatography (GC) (Bordagaray et al 2011;Farajzadeh et al 2010Farajzadeh et al , 2011Farajzadeh et al , 2012Farajzadeh and Khoshmaram 2013;Freitas et al 2014;Li et al 2014;Sarafraz-Yazdi et al 2012), GC with mass spectrometry (GC-MS) (Farajzadeh et al 2012;Freitas et al 2014;Sarafraz-Yazdi et al 2012), GC with tandem mass spectrometry (GC-MS/MS) (Li et al 2011, highperformance liquid chromatography (HPLC) (Bordagaray et al 2013(Bordagaray et al , 2014Gao et al 2012;Luo et al 2013;Wang et al 2011;Ye et al 2012), HPLC with tandem mass spectrometry (HPLC-MS/MS) (Juan-Garcia et al 2004;Li et al 2013;Wang et al 2014;Zhang and Xu 2014), and capillary electrophoresis (CE) (Chicharro et al 2003;Rodriguez et al 2001;Wu et al 2001). On the other hand, quick and effective sample preparation coupled with a reliable analytical method is imperative.…”

A rapid, efficient, and environmentally friendly method using vortex-assisted ionic liquid dispersive liquidliquid microextraction (VA-IL-DLLME) prior to highperformance liquid chromatography coupled with photodiode array detection (HPLC-PDA) has been developed for the determination of six triazole fungicides (triazolone, triadimenol, epoxiconazole, flusilazole, tebuconazole, and diniconazole) in various fruit juices. 1-Hexyl-3-methylimidazolium hexafluorophosphate ([C 6 MIM][PF 6 ]) and acetonitrile were used as extraction and dispersive solvents, respectively. A single factor experiment was selected to obtain the significant variables from the several related parameters that could affect the extraction efficiencies, such as the volume of IL and acetonitrile, extraction time, centrifugation time, and salt addition. Under the optimum conditions, an excellent linearity with correlation coefficients higher than 0.997 was obtained. Enrichment factors and average recoveries in three concentration levels ranged from 51 to 72, and 71.0 to 104.5 %, respectively, and the relative standard deviations (RSDs) from 1.4 to 11.8 %. The limits of detection (LODs) (S/N=3) for the six triazole fungicides were between 0.4 and 6.7 μg L −1 . The proposed method was successfully applied for the determination of trace amounts of triazole fungicides in various fruit juices including peach, apple, and orange juices.

“…In this case the dispersion is made by introducing air repeatedly sucking the sample-extractant mixture with a syringe until the solution becomes turbid. Very good RSD values were obtained in the works that used this technique (1-7%) as well as good recovery values (81-113%) [58][59][60][61].…”

“…Estos métodos involucran el uso de técnicas dispersivas y no dispersivas de extracción en las que comúnmente se emplean solventes, fluidos supercríticos u otras sustancias. Además, también suelen utilizarse técnicas de extracción y microextracción en fase sólida, extracción asistida por microondas o ultrasonidos (Barriada-Pereira et al, 2007;Farajzadeh & Khoshmaram, 2013;Sharif, Man, Hamid, & Keat, 2006;Wang et al, 2013).…”

En este trabajo se determinó la residualidad de plaguicidas organofosforados (OF) y organoclorados (OC) en los frutos de dos solanáceas comúnmente consumidas en la dieta diaria de la población del departamento del Quindío (Colombia): tomates (Lycopersicon esculentum Mill) cosechados en cultivos regionales y uchuvas (Physalis peruviana, L.) obtenidos en mercados de cadena. Con el fin de evaluar la calidad con la que se comercializan estos frutos, se midieron parámetros fisicoquímicos tales como el pH y la concentración de sólidos solubles (°Bx). El análisis de los plaguicidas en piel y pulpa de ambos frutos se realizó mediante cromatografía de gases con detección por microcaptura de electrones (GC-μ-ECD), empleando técnicas de extracción en fase sólida como pretratamiento de muestra. Como resultado del análisis cromatográfico se encontró la presencia de un total de 10 plaguicidas OF y OC tanto en la piel como en la pulpa de ambos frutos, algunos de ellos en concentraciones mayores a 0,13 ppm en tomate y 0,39 ppm en uchuva. Los resultados obtenidos en este estudio sugieren una alta residualidad de este tipo de fitosanitarios y ponen de manifiesto el uso desmesurado de estas sustancias en el cultivo de frutos de consumo masivo como el tomate y la uchuva. Esto revela el uso de malas prácticas agrícolas y la falta de un control más riguroso sobre el empleo de estos agroquímicos.
