“…Thus, analytical institutes require fast and efficient multiresidue methods in order to maximize the coverage of their monitoring activities. For this reason, researchers have reported many multiresidue analytical methods (Cook, J., et al, 1999, Fillion, J., et al, 2000, Hirahara, Y., et al, 2006, Luke, M. A., et al, 1975, Ueno, E., et al, 2004. These methods were optimized to monitor multiple residues efficiently and are used routinely in quarantine stations and laboratories.…”

“…24,27,28) Grapefruit was produced by natural crossing pomelo and orange, so it is necessary to note that similar interfering peaks appear over the entire product ions produced from the protonated molecule of imazalil on the chromatograms of the test solution of pomelo by LC conditions. In addition to the MS/MS system, EI-SIM/Scan mode GC-MS, 9) negative chemical ionization (NCI)-SIM/Scan mode GC-MS, 17) dual-column GC-ECD/ECD, 3,11) dual-column GC-FPD/NPD, [4][5][6] ESI-SIM/Scan mode LC-MS with diode-array detection (DAD), 13,14) and HPLC with post-column FLD for residual N-methyl carbamate pesticides, 24,29) were also adopted. Thus, the systematic method using plural separation and detection systems has been constructed.…”

In Japan, the Positive List System for the regulation of agricultural chemical residues in foods has been in force since May 29, 2006. Moreover, food poisoning caused by methamidophos-laced frozen gyōza dumplings came to light on Jan. 30, 2008. The news has set off alarms about the safety of not only perishables but also unexpected pesticides in processed foods. Therefore, a reliable systematic method was developed for determining pesticide residues in various foods. Firstly, ca. 200 target pesticides were selected by statistically analyzing the monitoring data in Aichi Prefecture. Secondly, a systematic method using plural separation and detection systems combining GC-MS/MS and LC-MS/MS as first priority was constructed. As the sample preparation method corresponding to the systematic method, a simple and easy acetonitrile extraction method, an auto-cleanup system combining GPC and mini-column SPE were developed. Thirdly, a new official multi-residue method that is able to determine a wide range of pesticides in various foods including fatty processed foods was developed. And finally, a comprehensive chromatographic detection system by dual-column GC-MS(/MS) and an interactive database without the use of pesticide standards was commercialized.

“…Esta técnica cuenta con detectores como el detector de captura de electrones y el detector de nitrógeno y fósforo, entre otros (Hunter, Riederer, & Ryan, 2010;Ueno, Oshima, Saito, & Matsumoto, 2003;Ueno et al, 2004). Hasta la fecha se han desarrollado numerosos métodos de análisis para la determinación de plaguicidas OF y OC en distintas solanáceas mediante la cromatografía de gases y diferentes detectores.…”

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.
