Trace level determinations of carbamate pesticides in surface water by gas chromatography–mass spectrometry after derivatization with 9-xanthydrol

Automatic generation of photochemically induced excitation-emission-kinetic four-way data for the highly selective determination of azinphos-methyl in fruit juices

“…131 La presencia de compuestos potencialmente perjudiciales para la salud humana y animal, como lo son los plaguicidas, es una problemática actual que requiere de medidas de control y regulación. 132 Entre la variedad de métodos analíticos que se emplean para el análisis de residuos de plaguicidas, en particular de los grupos de los benzimidazólicos (carbendazin, tiabendazol y fuberidazol) y los carbamatos (carbofurán, carbaril y 1-naftol), se pueden mencionar la espectroscopia de fluorescencia, 133,134,135 la cromatografía líquida acoplada a detector de arreglo de diodos, 136 de fluorescencia 137,138 y de espectrometría de masas, 139 la cromatografía de gases acoplada a detección de espectrometría de masas, 140,141 la cromatografía electrocinética micelar 142 y métodos electroquímicos. 143 En este trabajo se plantea la cuantificación de residuos de carbendazin, tiabendazol, fuberidazol, carbofurán, carbaril y 1-naftol en muestras de manzana, pera y ciruela, mediante generación y modelado de datos de tercer orden.…”

Graphene‐based pipette tip solid‐phase extraction with ultra‐high performance liquid chromatography and tandem mass spectrometry for the analysis of carbamate pesticide residues in fruit juice

“…Thus, pesticides and their metabolites and degradation products are likely to exist in fruit juice products especially when mechanical procedures are used for extraction during postprocessing . Carbamate pesticides including insecticides, herbicides, and fungicides are a large group of synthetic pesticides replacing organochlorine and organophosphorus pesticides due to their broad biological activity, less sustainability, and relatively low mammalian toxicity . Whereas, they can affect the nervous system of organisms as well as human being by inhibiting the activity of acetylcholine esterase and causing harm to human health .…”

Photoinduced chemiluminescence determination of carbamate pesticides

“…Therefore, prior derivatization is desirable when GC analysis is performed. 7 In LC, different detection techniques have been used, such as ultraviolet 8,9 or fluorescence, 10,11 but mass spectrometry is the preferred technique [12][13][14] because it provides high sensitivity and selectivity with LODs of a few pg mL -1 . However, this technique is not available for all laboratories due to the high cost and complexity of the instrumentation.…”
