Efecto del glifosato sobre la población en el área de influencia del Riohacha, sector de Larandia Caquetá

Abstract

This work was carried out in two phases, which were carried out in the field and in the laboratory; these focused on the determination of the effect of glyphosate on the population in the area of ​​influence of the river ax, sector of Larandia Caquetá. Phase I (field work) was attended by 100 people living in the area of ​​influence of the Larandia military base where the airplanes are ready for fumigation, to whom a survey based on four relevant aspects was applied: general information, occupational history, exposure to pesticides, hygiene measures and personal protection elements, to determine the frequency, use of pesticides and the impact generated by their use on the environment. At the same time, phase II (laboratory) was developed where the HPLC liquid chromatography technique was validated and subsequently analyzed 10 water samples taken at strategic points in the area of ​​interest. It was shown that 25% of the inhabitants of the area use glyphosate in their daily work and 75% of people use glyphosate together with other pesticides of the organophosphorus and carbamate families, which have, like glyphosate, a degradation. on the floor. In addition, 40% of the participants stated that they wash their work clothes on the riverbank, generating chemical reactions that in turn could affect the life cycle of the plants present in the ecosystem, by the direct discharge of waste from herbicides and detergents that are poured into the water source. In the laboratory it was determined that glyphosate responded to the different analytical detectors, but, below the limits of quantification, which indicates its degradation over time, in addition, in this analysis AMPA metabolite residuality was obtained.
