Description
Introducción: El impacto en la salud que ocasiona el uso de plaguicidas en los agricultores se debe principalmente a las prácticas inadecuadas en el manejo de los mismos. Objetivo: Identificar los posibles efectos adversos en la salud y el ambiente asociados al uso y manejo de plaguicidas en el cultivo de papa. Metodología: estudio descriptivo transversal en elmunicipio de Totoró, departamento de Cauca (Colombia), con una muestra de 125 trabajadores. A cada individuo seleccionado se le aplicó encuesta y recolectó una muestra de 10 ml de sangre para determinar la actividad de la enzima acetilcolinesterasa tanto en plasma como en eritrocitos por la técnica de Michel. Resultados: El 74,4% (n=93) de los trabajadores empleaban plaguicidas en su trabajo y el 49,6% (n=62) los usaban en el hogar. La mayor frecuencia de uso de plaguicidas tanto en el trabajo como en el hogar está dado por los organofosforados. En relación con la determinación de la actividad de la enzima acetilcolinesterasa, el 8,0% (n=10) de los individuos presentaron inhibición de la acetilcolinesterasa eritrocitaria. Conclusiones: El mayor porcentaje de los plaguicidas empleados en el trabajo pertenecen a la categoría toxicológica III, medianamente tóxicos, seguido por la categoría I (extremadamente tóxicos). El plaguicida más frecuentemente utilizado en el trabajo fue el Manzate de categoría toxicológica III, mientras que en casa fue el Furadan (categoría toxicológica I). La inhibición de la AChE fue mínima aunque se informó del uso de plaguicidas organofosforados, carbamatos y ditiocarbamatos, entre otros.
Introduction: The health impact caused by the use of pesticides on farmers is mainly due to poor practices in managing them. Objective: To identify possible adverse effects on health and the environment associated with the use and management of pesticides in potato crops. Metodology: cross sectional study in the municipality of Totoro, Cauca department (Colombia), with a sample of 125 workers. Each selected individual survey was applied and collected a sample of 10 ml of blood to determine the activity of the enzyme acetylcholinesterase both plasma and erythrocytes by Michel technique. Results: 74.4% (n = 93) of workers employed pesticides in their work and 49.6% (n = 62) used them at home. The highest frequency of pesticide use both at work and at home is given by organophosphates. Regarding the determination of the activity of the enzyme acetylcholinesterase, 8.0% (n = 10) of individuals they presented erythrocyte acetylcholinesterase inhibition. Conclusion: The highest percentage of the pesticides used at work belong to the toxicity category III, moderately toxic, followed by the category I (extremely toxic). The pesticide used most often at work was Manzate of toxicity category III, while at home was the Furadan (toxicological category I). AChE inhibition was minimal but the reported the use of organophosphates, carbamates and dithiocarbamates, among others.
