“…The detection methods of propisochlor were mainly based on chromatography, such as gas chromatography (Mekonen et al, 2016), high performance liquid chromatography (HPLC) coupled with mass spectrometry (Baris et al, 2016), ultra-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) was also developed for the determination of propisochlor (Wang, Zhang, Nesterenko, Eremin, & Shen, 2007). Although instrumental analytic methods could be used for the determination of propisochlor with appropriate limit of detection (LOD) and sensitivity, these instrumental methods are complex in sample preparation and expensive, which restricted their wide application.…”

The herbicide propisochlor can be introduced into the water cycle via agricultural activities, thus possibly leading to harmful ecological effects. It is significant for the development of a rapid method for propisochlor analysis in water. In this work, a rapid homogeneous immunoassay based on fluorescence polarization immunoassay (FPIA) was firstly developed for the determination of propisochlor in pond water. The developed FPIA assay can be completed within only 14 min; the 50% inhibition concentration (IC 50 ) was 125.1 ng/mL and the limit of detection was 8.4 ng/mL. The recoveries of propisochlor in pond water ranged from 80.0% to 86.6%. A high performance liquid chromatography confirmation showed a good correlation with the developed FPIA (R 2 = 0.9748). The developed FPIA exhibited satisfactory rapidity, high sensitivity and excellent specificity, meeting the standards of the screening assay of propisochlor in pond water on site. The molecular modeling showed that the alkoxyalkyl of chloroacetamide herbicides exerted important effects on the herbicide-antibody binding.

“…Biofísicamente la comunidad se encuentra expuesta a niveles de riesgo altos; tanto por factores de dispersión, falta de concientización de los agricultores en la aplicación de buenas prácticas agrícolas (GAP) y manejo inadecuado de pesticidas, además del contexto de aplicación y las condiciones geológicas, hidrológicas y meteorológicas locales 28 ; como por procesos inseguros que se realizan en las labores agrícolas evaluadas con nivel de riesgo I y II según la matriz GTC 45 16 .…”

“…Sin embargo, aparentemente la situación puede empeorar debido a que los agricultores tienen la tendencia a aplicar plaguicidas similares a medida que producen cultivos análogos 28 , lo cual fue corroborado por medio de observación directa en la zona de estudio.…”

Riesgos en la salud de agricultores por uso y manejo de plaguicidas, microcuencaLa PilaHealth risks of farmers for using and handling pesticides in the watershed "La Pila"Cristian Alexander Jiménez-Quintero 1 , Andrés Pantoja-Estrada 2 , Hugo Ferney Leonel 3* ResumenIntroducción: El corregimiento de Cabrera del municipio de Pasto, fundamenta su economía en el sector agropecuario, actividad que demanda el uso y manejo de variados productos químicos cuyo empleo conlleva riesgos para la salud. Objetivo: Identificar los principales riesgos a los cuales están expuestos los campesinos agricultores de la microcuenca La Pila , municipio de Pasto, por el uso y manejo inadecuado de plaguicidas en sus labores de producción. Materiales y métodos: Se comparó los resultados obtenidos en la simulación de la dispersión de plaguicidas a través del Software HYSPLIT libre y la evaluación de los riesgos por contacto inmediato identificados a través de criterios establecidos en la GTC45 de ICONTEC. Resultados: Se pudo determinar que el factor de riesgo al cual se encuentran sometidos los agricultores de la zona es de tipo químico; que la dispersión de dichos contaminantes alcanza una longitud máxima de dispersión de 250 m y que a pesar que los trabajadores conocen de la importancia de la implementación de Elementos de Protección Personal no los utilizan como barreras para atenuar e impedir la materialización de los peligros. Conclusiones: Los riesgos identificados son más latentes en los agricultores de la zona media y baja de la microcuenca.Palabras clave: Factores de riesgo; mapa de riesgo; plaguicidas; impactos en la salud.

AbstractIntroduction: The village of Cabrera, in the municipality of Pasto, bases its economy on agriculture, which requires the use and handling of various chemicals that can cause health risks. Objective: To identify the main risks to which farmers are exposed for the use and improper handling of pesticides in their production work in the watershed called "La Pila" in the municipality of Pasto. Materials and Methods: The results obtained in the simulation of the dispersion of pesticides through HYSPLIT free Software and the risk assessment for immediate contact identified through established criteria in GTC45 ICONTEC were compared. Results: It was determined that the risk factor to which farmers in the area are subjected to is of chemical type; besides, the dispersion of these pollutants reaches a maximum length of dispersion of 250 m-However, despite the fact that workers are aware of the importance of the Universidad y Salud

“…After application, the movement of pesticides in the soil can occur through leaching, runoff and volatilization processes (Vieira et al, 1999), that can promote contamination of soil and surface water and groundwater. In addition, the contamination of water located near agricultural areas by pesticide residues can occur during the application of these substances, being of great concern (Mekonen et al, 2016).…”

Kinetic studies of sulfentrazone herbicide dechlorination by Fe/Ni nanoparticles were performed in the presence of different electrolytes such as: Cl-, SO 4 2-, NO 3-, Cu 2+ , Na + and Zn 2+. In the presence of Cland SO 4 2the reaction occurred efficiently, reaching approximately 100% of dechlorination after 30 minutes of reaction. In the presence of NO 3 and Cu 2+ ions the sulfentrazone dechlorination was significantly inhibited, because these ions tend to compete with the substrate for the electrons donated by Fe 0. In the presence of Na+ ions, the dechlorination efficiency remained approximately 100%, however, this electrolyte provided an increase on the reaction rate, due to the increase of the ionic strength in the system. The Zn 2+ ions has no influence on the dechlorination efficiency, but the reaction rate was reduced due to the formation of a protective layer formed by the sorption of Zn 2+ ions on the surface of the nanoparticles.
