description The strong demand for agricultural production has led to an indiscriminate use of agrochemicals causing the decline in the quality of surface waters. In the agricultural community of Bailadores, Municipality of Rivas Davila, Mérida State, Venezuela, the rivers of Las Tapias, Las Playitas and Mocoties were monitored for the presence of pesticide residues during 2008 and 2010. Water samples were subjected to solid phase extraction and analyzed for the presence of pesticide residues by HPLC with diode array detector (SPE-HPLC-DAD) using a validated multiresidual method. The pesticide residues that were detected at higher frequencies and greater concentrations were the following: clorpirifos (302.9±0.9 μg/L), diazinon (459±4.0 μg/L), dimetoato (55±3.0 μg/L), mancozeb (108±1.0 μg/L) and metamidofos (107±8.0 μg/L), which are all found in the list of highly dangerous pesticides by the International Pesticides Control Network. In all cases, the levels exceeded the limits set by the European Union and the Environmental Protection Agency of the United States. The total concentration of organophosphates also exceeded the limits established by the Venezuelan law. The results of this study demonstrate a high level of pesticide contamination of the principal surface water courses in the Municipality of Rivas Dávila. It is recommended to implement a pesticide monitoring program and the need to change the current mode of production to a sustainable agricultural practice, which will allow to reduce the use of agrochemicals and their negative consequences to the environment and the human health.

La fuerte demanda de producción agrícola conlleva al uso indiscriminado de agroquímicos causando el desmejoramiento de la calidad de las aguas superficiales en la comunidad agrícola de Bailadores, Municipio Rivas Dávila, Estado Mérida, Venezuela. Residuos de trece plaguicidas, seleccionados de una lista de los 35 principios activos más utilizados en la región, fueron monitoreados durante 2008 y 2010 en los ríos Las Tapias, Las Playitas y Mocoties, que es el principal recurso hidrológico en la región. Las muestras de agua fueron sometidas a una extracción en fase sólida y se analizaron los residuos de plaguicidas mediante HPLC con detector de arreglo de diodos (SPE-HPLC-DAD). Los plaguicidas detectados con mayor frecuencia y en concentraciones más altas fueron clorpirifos, diazinon, dimetoato, metamidofos y mancozeb, todos se encuentran en la lista de plaguicidas altamente peligrosos por la Red Internacional de Control de Plaguicidas. En todos los casos, los niveles detectados superan los límites establecidos por la Unión Europea y la Agencia de Protección Ambiental de los Estados Unidos, y el total de las concentraciones de los organofosforados supera los límites establecidos por la legislación Venezolana. Los resultados de este estudio demuestran un alto nivel de contaminación  por plaguicidas de los principales cursos de aguas superficiales del Municipio Rivas Dávila. Se recomienda continuar con un programa de monitoreo de plaguicidas y la necesidad de cambiar el modo de producción actual hacia una práctica agrícola sostenible, que permita reducir la utilización de agroquímicos y sus consecuencias negativas para el medio ambiente y la salud humana.Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2012-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/25666Revista Internacional de Contaminación Ambiental; Vol. 28 Núm. 4 (2012); 289-301Revista Internacional de Contaminación Ambiental; Vol. 28 No. 4 (2012); 289-3010188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/25666/31202Derechos de autor 2017 Revista Internacional de Contaminación Ambientalinfo:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/256662024-08-16T19:00:29Z
