description |
During the second half of twentieth century, Repelón was known as the main agricultural source in the Atlántico department. A town, which like most of the country at that time, had cultivation as the motor of its development, standing out the cotton, tomato and fruit crops in general, as well as having an irrigation district that supplied the fields of water throughout the year. Several factors slowly undermined the agricultural production on region, increasing the use of fertilizers to maintain the production level and pesticides to keep out plagues in order to ensure food security. These, caused the deposition of toxic compounds such as organochlorides in Repelon soils, which at that time they were used freely on cotton crops and poorly regulated. The presence of these noxious compounds on soils might become a serious risk for the productive purpose of soil, from economic, sanitary and environmental perspective. Considering the above, concentrations of toxic compounds such as organochlorine pesticides, (Heptachlor Benzene, Aldrin, Endosulfan, Dieldrin, Endrin) were analyzed by Gas Chromatography. Otherwise, concentrations of heavy metals (Mercury, Lead, Nickel, Zinc, Copper, Chrome and Cadmium), were analyzed by Inductively Coupled Plasma Emission Mass Spectroscopy (ICP-MS). Samples were taken from agricultural soils belonging to the irrigation district of Repelon, at the south region of Atlantico department, in Colombia. Through this study area, it was used a random sampling in zigzag which started with the location of ten sampling points with historical intensive agricultural production. For every heavy metal that was analyzed, excluding Cadmium, they were found analytically detectable concentrations (greater than the detection limit of 0.01 mg/kg). However, pesticides concentrations found were not quantitative values, because they were below the detection rate of analytical technique (2 . The pollution degree of heavy metals was established through the Geoaccumulation Index (Igeo) and Enrichment Factors (EF). In the case of Copper, moderate enrichment was found in all points, whereas Chromium showed a minimal enrichment in points 5, 7 and 8, and moderate enrichment in the other analyzed points, while other metals presented minimal enrichment at all points. On the other hand, the Geoaccumulation Index showed that the soil was moderately polluted with Copper at all points as well as with Chromium excepting points 3 and 4. For Zinc, just point 9 is moderately polluted and rest of the samples are little polluted. In the case of Nickel, only point 3 is not polluted, while the others are little polluted. Surprisingly, the soils are not polluted either with Mercury, Lead or Cadmium. Finally, presented results prove that heavy metals requiring more attention in Repelón irrigation district are Chromium and Copper due to their irregular concentrations in some zones, deducing a common source of pollution which requires further studies to establish its causes. Additionally, although the concentration from the other metals was low, it must be correlated with environmental factors and physicochemical characteristics of the soil to define its potential toxicity as well as the impacts on human health. |

Contando además con un distrito de riego que abastecía los campos de agua durante todo el año. Distintos factores socavaron lentamente la actividad agrícola de la región, incrementándose el uso intensivo de fertilizantes para mantener la productividad de los cultivos y el uso de plaguicidas para mantener al margen a las plagas y así también garantizar la seguridad alimentaria, lo que ocasionó una deposición de distintos compuestos tóxicos en los suelos, como los plaguicidas organoclorados, que para ese periodo estaban muy poco regulados y eran usados libremente en cultivos de algodón. La presencia de dichos compuestos tóxicos en el suelo puede convertirse en un riesgo potencial, desde la perspectiva económica, sanitaria y ambiental, y alterar la vocación productiva del suelo Teniendo en cuenta lo anterior, se analizaron las concentraciones de compuestos tóxicos, tales como los plaguicidas organoclorados (Heptacloro benceno, Aldrín, Endosulfán, Dieldrín, Endrín), por Cromatografía de Gases y los metales pesados (Mercurio, Plomo, Níquel, Zinc, Cobre, Cromo y Cadmio), por Espectrometría de Masas con Plasma Acoplado Inductivamente (ICP-MS), en suelos agrícolas del distrito de riego de Repelón, sur del Atlántico, Colombia. Se realizó una recolección de muestras compuestas en diez (10) zonas con historial agrícola. Para todos los metales pesados analizados, se encontraron concentraciones detectables analíticamente (mayores al límite de detección de 0.01 mg/kg) a excepción del Cadmio. Mientras que para los plaguicidas organoclorados, las concentraciones encontradas no fueron cuantitativas para ninguno, ya que se encontraban bajo el límite de detección de la técnica analítica (2 ). El grado de contaminación de los metales pesados fue establecido mediante el índice de geoacumulación (Igeo) y el factor de enriquecimiento (EF). Encontrándose enriquecimiento moderado para Cobre en todos los puntos, el Cromo presento un enriquecimiento mínimo en los puntos 5, 7 y 8 y moderado en los demás puntos de estudio. Mientras que los demás metales presentaron enriquecimiento mínimo en todos los puntos. Por otro lado, el índice de geoacumulación mostró que el suelo estaba medianamente contaminado con Cobre en todos los puntos; por su parte el Cromo en todos los puntos excepto en los puntos 3 y 4, presentó una mediana contaminación. Para Zn solo el punto 9 está medianamente contaminado y los demás puntos poco contaminados. Mientras que para el Ni todos los puntos están poco contaminados a excepción del punto 3, que no está contaminado. Para Mercurio, Plomo y Cadmio no se presentó contaminación en ninguno de los puntos evaluados. Los metales que requieren mayor atención en el distrito de Riego de Repelón, según este estudio son el Cromo y el Cobre, debido a sus concentraciones irregulares en algunas zonas, lo que permite suponer una fuente de contaminación común y requiere un mayor estudio para establecer dicho origen. Además, aunque la concentración de los demás metales, fue baja, deben correlacionarse con los factores ambientales y características fisicoquímicas del suelo para definir su toxicidad potencial y su impacto sobre la salud humana.Cervantes Fuentes, Duvan Salomón-a2edda6d-cf29-46e0-b143-fe75fe54bf13-600spaAtribución – No comercial – Compartir igualinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Plaguicidas organocloradosmetales pesadosÍndices de contaminaciónRepelónEvaluación de compuestos tóxicos: plaguicidas órganoclorados y metales pesados en suelos agrícolas del distrito de riego de Repelón - AtlánticoTrabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fTextinfo:eu-repo/semantics/bachelorThesishttp://purl.org/redcol/resource_type/TPinfo:eu-repo/semantics/acceptedVersionIngeniería AmbientalPublicationORIGINAL1140881790 1045734323.pdf1140881790 1045734323.pdfapplication/pdf2722409https://repositorio.cuc.edu.co/bitstreams/6137414a-d5dc-4f7a-b8dc-e6ed4d5da834/downloadf802590145e9740543ce4783143c5c22MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748https://repositorio.cuc.edu.co/bitstreams/a30e6713-1fe9-454c-a779-a50b7d76bb8c/download8a4605be74aa9ea9d79846c1fba20a33MD53THUMBNAIL1140881790 1045734323.pdf.jpg1140881790 1045734323.pdf.jpgimage/jpeg25412https://repositorio.cuc.edu.co/bitstreams/85438986-8a60-4f12-a049-51ea9915aad5/download8c48eb63d97267a8aeeb3f35cfe4fc8dMD55TEXT1140881790 1045734323.pdf.txt1140881790 1045734323.pdf.txttext/plain180375https://repositorio.cuc.edu.co/bitstreams/53656bd5-5de2-4513-a865-c4d07134a335/download8e4618f11971a57e70ac3adb0e437a0dMD5611323/236oai:repositorio.cuc.edu.co:11323/2362024-09-17 11:00:58.996open.accesshttps://repositorio.cuc.edu.coRepositorio de la Universidad de la Costa CUCrepdigital@cuc.edu.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 |
