Three representative onion production systems were selected, registering all types of pesticides used during the crop cycle. At the end of crop cycle, samples of onion were taken and analyzed by gas chromatography to determinate levels of OF and OC residues. The results indicated a main use of fungicides, use of highly toxic OC and OF insecticides, overdosage, and high number of applications. Onions of two of the studied systems showed residues of the herbicide OC butachlor ranging from 0.86 to 1,80 mg·kg-1, which were considered unacceptable. Residues of the insecticide OF chlorpiryfos were detected in the three systems with means between of 0.01 and 0.02 mg·kg-1, values that did not reach the maximum residue level established by FAO and EPA. In one of the systems 0.02 mg·kg-1 of residues of the insecticide OF dimethoate were detected, although below the maximum residue level according to FAO. The paper concludes that there was a relation between the inadequate use of pesticides and the presence of residues in the harvested onion]]></p></abstract>

Éstos serían potencialmente dañinos a la salud humana y podrían incidir negativamente en su comercialización (Guerrero, 2003).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">La depresión de Quíbor, ubicada en el estado Lara, Venezuela, fue declarada en 1982 como zona de aprovechamiento agrícola con una superficie de 43.395 ha. Se caracteriza por presentar un promedio anual de precipitación de 550 mm y temperaturas medias alrededor de 24 ºC y es la principal zona productora de cebolla, contribuyendo con el 69% de la superficie sembrada y el 70 % de la producción a nivel nacional (MAT, 2005).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">El monocultivo de la cebolla en la zona ha generado problemas de plagas cuyo control se realiza con insecticidas organoclorados (OC) y organofosforados (OF) (Díaz et al., 1995). Los OC son moléculas que contienen carbono, hidrógeno y cloro; son altamente tóxicos, bioacumulables y muy poco biodegradables. Su principal acción tóxica es ejercida sobre el sistema nervioso, interfiriendo con el balance entre los iones sodio y potasio en las neuronas, impidiendo la transmisión normal de los impulsos nerviosos tanto en insectos como en mamíferos. Se acumulan en tejidos grasos pudiendo causar intoxicación crónica. Los OF son ésteres de fósforo en combinaciones variables con el oxígeno, carbono, azufre y nitrógeno. Su acción es neurotóxica, siendo mucho más tóxicos en los vertebrados, aunque son químicamente inestables y no son persistentes. Inhiben la función de ciertas enzimas del sistema nervioso afectando la sinapsis neurona/neurona o neurona/músculo, ocasionando parálisis (Ware y Whitacre, 2004).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Residuos de insecticidas en hortalizas, incluida la cebolla, han sido ampliamente reportados a nivel mundial (Ritcey et al., 1991; Yun, 1999; Guerrero, 2003). En la depresión de Quíbor se han reportado intoxicaciones por OC, OF y carbamatos, niveles alterados de colinesterasa en sangre, presencia de OC en leche materna y diferentes tipos y grados de malformaciones congénitas en neonatos, (Tagliaferro et al., 1999; Tagliaferro, 2002). El objetivo de este trabajo fue investigar el uso de plaguicidas, con énfasis en los insecticidas OC y OF, y su relación con los niveles de residuos en la cebolla producida en la zona.</font></p>     <p class="5Captulo" style="mso-pagination: none; page-break-after: auto; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2"><b>MATERIALES Y MÉTODOS</b></font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">La investigación se desarrolló en la depresión de Quíbor, en la que se seleccionaron tres sistemas representativos de producción de cebolla identificados como A, B y C, ubicados en el municipio Jiménez, estado Lara, que utilizaron control químico de plagas. Los sistemas tenían en común superficies de 15 a 20 ha, riego por gravedad, utilización de maquinarias y equipos, con más de tres hectáreas cultivadas con cebolla y productores con más de diez años de experiencia en el cultivo.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Para la obtención de la información se estableció un programa de visitas semanales a los sistemas de producción a fin de cubrir las diferentes fases del cultivo en función del manejo de plaguicidas que hacen los productores: fase de semillero (0-30 días);&nbsp; fase de trasplante (30-80 días) y fase de cosecha (80 días-cosecha). Se registraron cada uno de los insecticidas utilizados en cada fase, las dosis y el número de aplicaciones. Al finalizar el ciclo de cultivo se tomaron muestras de cebolla siguiendo la metodología establecida en el Reglamento Técnico de Costa Rica 213 (RTCR, 1998) y en el Real Decreto Español 290 (RDE, 2003). Cada una de &nbsp;las &nbsp;parcelas &nbsp;de &nbsp;producción &nbsp;fue &nbsp;dividida &nbsp;en diez partes iguales, y utilizando el método aleatorio sistemático fueron extraídas muestras siguiendo un parámetro de muestreo de puntos en zig-zag previamente establecido. Las muestras tuvieron 2,0 kg de peso como mínimo, repitiéndose este procedimiento cuatro veces. Posteriormente, en el laboratorio el peso de cada muestra se redujo al azar hasta 1 kg de acuerdo a la metodología de Dramiñski y Zagorzycki (1984) para determinar residuos de OC y OF mediante cromatografía de gases.

(1984) quienes reportaron que los productores de cebolla de la zona de Río Tocuyo en el estado &nbsp;Lara &nbsp;usaban &nbsp;17 &nbsp;marcas &nbsp;comerciales &nbsp;de&nbsp; insecticidas&nbsp; de&nbsp; las &nbsp;cuales &nbsp;nueve &nbsp;eran OF &nbsp;(52,94 %). Márquez (1999) encontró que, en zonas productoras de cebolla de San José, Bongabon y Muñoz en Filipinas, 13 de los 26 insecticidas utilizados eran OF. Asimismo, señaló que estos productos representaron en promedio el 50% del total de plaguicidas. Dudley et al. (2002) reportaron en la región de Río Grande (Texas) el uso mayoritario de insecticidas OF en cebolla (13 marcas comerciales). Epstein y Bassein (2003) indicaron que en Estados Unidos el uso de plaguicidas de alto riesgo (OF y carbamatos) ha declinado en 14 %, pasando de 206 millones de kg de i.a. utilizados en 1992, a 177 millones en 2000. Sin embargo, los grupos mencionados siguen representando el 40% del total de plaguicidas empleados.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Holland y Rahman (1999) señalaron que en Nueva Zelanda, entre 1984 y 1998, se ha producido una importante reducción en el uso de OF; sin embargo, en 1998 la agricultura de ese país utilizó 267.500 kg de i.a. de insecticidas, de los cuales 150.000 kg eran OF (56,1 %). Destacaron que en el área de Waikato-Pukekohe donde se cultivan 5.400 hectáreas de cebolla, se utilizaron en promedio 4 kg de i.a.·ha<sup>-1</sup>·año<sup>-1</sup> de insecticidas de los cuales 1,9 kg eran OF (47,5 %).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Stivers-Young et al. (2003) indicaron que en el estado de New York entre 1978 y 1998 el uso de insecticidas en cebolla declinó, pasando de un promedio de 5,4 a 1,5 kg i.a.·ha en 1998. Sin embargo, &nbsp;para &nbsp;todos &nbsp;los &nbsp;cultivos &nbsp;en &nbsp;conjunto, los OF representaron el 54 % del total de insecticidas usados. Garthwaite et al. (2003) señalaron que en el Reino Unido entre 1999 y 2003 el uso de insecticidas OF en cebolla decreció un 43%, mientras que el uso de piretroides aumentó un 12%. Entre 1991 y 1995 los OF eran el &nbsp;principal &nbsp;grupo &nbsp;químico; &nbsp;sin embargo, &nbsp;su uso actual &nbsp;ha &nbsp;decrecido 87 % comparado &nbsp;con 1999, y 94 % comparado con 1991. La tasa de aplicación &nbsp;promedio &nbsp;de &nbsp;insecticidas &nbsp;fue &nbsp;de &nbsp;0,44 kg·ha<sup>-1</sup> en 1991, mientras que en el 2003 fue de 0,12 kg·ha<sup>-1</sup>.&nbsp;</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">En el presente estudio, los plaguicidas más tóxicos se ubicaron en el renglón de los insecticidas para todos los sistemas. En el sistema A, más de la mitad de los insecticidas eran moderadamente tóxicos (MT) y una tercera parte altamente&nbsp; tóxicos (AT). En&nbsp; el&nbsp; sistema&nbsp; B,&nbsp; dos&nbsp; tercios&nbsp; de&nbsp; los&nbsp; insecticidas&nbsp; eran MT, mientras que los AT y los extremadamente tóxicos (ET) totalizaron un 22% en forma conjunta. En el sistema C, los insecticidas AT y los ET sumaron un 40% en forma conjunta (<a href="#cuad6">Cuadro 6</a>).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><a name="cuad6"></a></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="center"><font face="Verdana" size="2"><b>Cuadro 6.</b> Grupo químico y toxicidad de los insecticidas utilizados en cada sistema de producción en el cultivo de cebolla en la depresión de Quíbor, estado Lara, Venezuela</font></p>     <div align="center">   <table border="0" cellspacing="1" width="560%" style="width:100.0%;  border-collapse:collapse;mso-padding-alt:0cm 1.4pt 0cm 1.4pt">     <tr style="height:16.15pt">       <td width="8%" style="width:8.18%;border-top:solid windowtext .5pt;   border-left:none;border-bottom:solid windowtext .5pt;border-right:none;   padding:0cm 1.4pt 0cm 1.4pt;height:16.15pt">             <p class="MsoNormal" align="justify" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-right: -1.15pt; margin-bottom: 0"><font face="Verdana" size="2">Sistema</font></p>       </td>       <td width="18%" nowrap style="width:18.92%;border-top:solid windowtext .5pt;   border-left:none;border-bottom:solid windowtext .5pt;border-right:none;   padding:0cm 1.4pt 0cm 1.4pt;height:16.15pt">             <p class="MsoNormal" align="center" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-right: -1.15pt; margin-bottom: 0"><font face="Verdana" size="2">Nombre         comercial</font></p>       </td>       <td width="18%" nowrap style="width:18.54%;border-top:solid windowtext .5pt;   border-left:none;border-bottom:solid windowtext .5pt;border-right:none;   padding:0cm 1.4pt 0cm 1.4pt;height:16.15pt">             <p class="MsoNormal" align="justify" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-right: -1.15pt; margin-bottom: 0"><font face="Verdana" size="2">Ingrediente         activo</font></p>       </td>       <td width="22%" nowrap style="width:22.32%;border-top:solid windowtext .5pt;   border-left:none;border-bottom:solid windowtext .5pt;border-right:none;   padding:0cm 1.4pt 0cm 1.4pt;height:16.15pt">             ]]></body>

Andrés et al. (1999)&nbsp; en&nbsp; la&nbsp; zona&nbsp; de&nbsp; Nueva&nbsp; Vizcaya, Filipinas, determinaron que el 90% de los agricultores utilizaba plaguicidas químicos y el 94% desconocía los peligros que supone para la salud la manipulación y exposición a éstos compuestos químicos. La mayoría de los insecticidas utilizados eran OF y carbamatos, empleándose en forma indiscriminada un&nbsp; total de 22 productos. En contraste, Dudley et al. (2002) tratando de identificar factores claves que contribuyen en la elección de un insecticida, realizaron encuestas a productores de cebolla en Texas, logrando establecer que el 60% escoge aquellos insecticidas menos peligrosos para los enemigos naturales de la plaga, reduciéndose por esta misma causa la frecuencia de aplicación. Señalaron también que el 46% se deja orientar por las casas comerciales en su elección, mientras que el 40% consideró la experiencia de otros productores. Sin embargo, esta actitud requiere de un conocimiento de los aspectos ambientales relacionados al uso de insecticidas.&nbsp;</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Kovach et al. (1992) calcularon un algoritmo para cuantificar por anticipado a través de un coeficiente de impacto ambiental (EIQ), el efecto del uso de un determinado insecticida sobre el trabajador expuesto, el consumidor y el ambiente. En productores de cebolla de Texas, la reducción del uso de sólo dos OF y el incremento de uso de piretroides logró una reducción del valor del EIQ de 83 a 31 entre 1990 y 1998, pudiéndose observar claramente la amenaza ambiental que representan los insecticidas OF.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">En &nbsp;las &nbsp;tres etapas &nbsp;en&nbsp; que &nbsp;se &nbsp;dividió &nbsp;el &nbsp;ciclo del cultivo (semillero,&nbsp; trasplante y cosecha), todos los sistemas se usaron insecticidas químicos para el control de plagas. Se observó que la mayoría &nbsp;fueron &nbsp;utilizados &nbsp;en &nbsp;dosis &nbsp;superiores &nbsp;a las recomendadas por el fabricante. La inobservancia de las recomendaciones del fabricante, entre otros factores, actuó como agravante del manejo inadecuado de estos productos químicos.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">En los sistemas A y C, los insecticidas usados en la etapa de semillero se aplicaron siguiendo las&nbsp;&nbsp; indicaciones del &nbsp;fabricante,&nbsp; mientras que en el sistema B, el 66,7 % de los productos aplicados se utilizaron con dosis por encima de las recomendadas.

Las principales causas de los niveles de residuos de plaguicidas encontrados en hortalizas son exceso de dosis, aplicación de los productos con mayor frecuencia de la recomendada y la inobservancia del tiempo recomendado entre la última aplicación y la cosecha (OPS, 2001; Guerrero, 2003).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Los análisis aplicados a las muestras de cebolla detectaron la presencia del insecticida OF clorpirifos (éster, ácido fosforotioico 0,0 dietilo 0 3,5,6 tricloro 2 piridinil) en el 100% de las muestras del sistema A y B,&nbsp; y en el 25% de las muestras del sistema C. Los residuos detectados del insecticida clorpirifos estuvieron por debajo de los límites máximos permitidos por la FAO y la EPA (0,05 y 0,5 mg·kg<sup>-1</sup>, respectivamente). No hubo diferencias significativas (P&gt;0,05) entre las cantidades del insecticida detectado en los tres sistemas estudiados.

En el sistema B se aplicaron un 2,0 L en la etapa de trasplante-cosecha y 2,0 L en la etapa de 80 días-cosecha. En el sistema C se aplicó 1,5 L en la etapa de 80 días-cosecha. En términos porcentuales, el clorpirifos representó el 16,4 % del total de insecticidas aplicados en el sistema B, el 7,9 % en el sistema A y &nbsp;el &nbsp;1,57 % &nbsp;en &nbsp;el &nbsp;sistema &nbsp;C. &nbsp;A &nbsp;pesar &nbsp;de &nbsp;la relativa poca cantidad empleada de este insecticida en los diferentes sistemas, fue capaz de generar cantidades de residuos aun en su nivel más bajo de uso y que corresponde al del sistema C. Residuos de clorpirifos en diferentes hortalizas, incluyendo cebolla, han sido previamente reportados por Ritcey et al. &nbsp;(1991), &nbsp;Yun (1999) y Guerrero (2003).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">En términos de volúmenes de uso para 1998, el clorpirifos era el insecticida número uno en el mundo. En Estados Unidos ha sido uno de los principales causantes de intoxicaciones agudas por insecticidas. En ese país, el metabolito primario del clorpirifos, el 3,5,6 tricloro 2 piridinol ha sido el segundo producto químico detectado con mayor frecuencia en los alimentos (RAPAL, 2002). Márquez (1999) reportó&nbsp; al insecticida clorpirifos junto con el piretroide cipermetrina como los dos insecticidas más usados en las zonas productoras de cebolla de Filipinas. Asimismo, Garthwaite et al. (2003) señalaron al clorpirifos como&nbsp; uno de los cinco insecticidas más usados en cebolla en el Reino Unido.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Respecto al dimetoato, éste es un insecticida OF sistémico y de contacto, moderadamente tóxico, con LD50 oral de 150 mg·kg<sup>-1</sup>. Residuos de este producto en hortalizas incluyendo cebolla han sido reportados por Abou-Arab (1999), Frank et al. (1990) y Sinha et al. (1992).</font></p>     <p class="8Columnas" style="line-height: 100%; mso-pagination: none; word-spacing: 0; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Para el butaclor (grupo de las cloroaceta-nilidas) no existen valores de LMR establecidos por la FAO o la Unión Europea. La EPA no los incluye&nbsp; por estar su uso prohibido en Estados Unidos. Esto implicaría que, en general, los residuos de butaclor encontrados en las muestras son&nbsp; inaceptables. Baran et al. (2004) estudiaron el comportamiento de los dos metabolitos del acetoclor (ácido etansulfónico y ácido oxalínico) en el suelo, encontrándose residuos del primero&nbsp; en profundidades hasta de 70 cm, y del segundo hasta de 20-30 cm. Residuos de ambos metabolitos fueron detectados en la superficie del suelo hasta 344 días después de su aplicación, indicando que existe cierto grado de conocimiento sobre la adsorción, lixiviación y degradación de estos productos en el suelo, pero muy poca información está disponible con respecto a las cloroacetanilidas en general. En los Estados Unidos, Reino Unido y Filipinas, las cloroacetanilidas están dentro de los herbicidas más utilizados en cebolla. Residuos del producto en cebolla han sido reportados por Tamiselvan y Sundararajan (1999).</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">En el presente ensayo el butaclor no fue reportado como utilizado por ninguno de los&nbsp; sistemas estudiados y en ninguna de las etapas en que se dividió el ciclo de cultivo el productor señaló su uso. Asimismo, el personal responsable de las aplicaciones con quien se estableció rutinas de chequeo tampoco mencionó su utilización. Esto induce a pensar, dada la persistencia característica de los organoclorados, que el campo pudo estar contaminado con anterioridad por aplicaciones realizadas en cultivos anteriores, convirtiéndose el suelo en el último reservorio de residuos que tendrían que ser degradados o mineralizados por los microorganismos.</font></p>     <p class="8Columnas" style="mso-pagination: none; word-spacing: 0; line-height: 100%; margin-bottom: 0" align="justify"><font face="Verdana" size="2">Oh et al.
