Resumen
Se realizó una caracterización ecotoxicológica de los residuos petrolizados generados en cuatro estaciones de servicios de la Ciudad de Manta. Se tuvo en cuenta que los contaminantes generados se consideran peligrosos y altamente capaces de generar efectos deletéreos en los diferentes compartimentos del ecosistema; se hizo necesario conocer la magnitud y alcance del potencial tóxico que poseen cada uno de estos residuos en los diferentes niveles bióticos y compartimentos ambientales sobre los que inciden. Para lograr este propósito se recolectaron muestras dos veces a la semana, durante un período de tres meses; a partir de lo cual se procedió a diseñar una ruta crítica ecotoxicológica que posibilitó la evaluación de dichos contaminantes con el uso de biomodelos experimentales representativos de los ambientes afectados. Se determinó el efecto que causan los residuales generados, en las Estaciones de Servicios de Manta, sobre la microflora y los animales de los suelos impactados, y en la misma medida se determinaron las afectaciones que estos contaminantes generan sobre el poder germinativo de las plantas representativas de los ecosistemas impactados. Para el procesamiento, análisis y discusión de los resultados se utilizó un diseño no experimental y longitudinal auxiliado por programas estadísticos profesionales adecuados a los diseños experimentales. La conclusión del estudio deja en claro el daño que causan sobre el ecosistema los residuos petrolizados generados en las Estaciones de Servicios; a partir de lo cual se recomienda crear planes de manejos en cada una de las estaciones de servicios, encaminados a minimizar el impacto que sobre el medioambiente ocasionan los contaminantes generados en las mismas.
Ecotoxicological characterization was performed petrolizados waste generated in four service stations Manta City. We took into account that pollutants generated are considered hazardous and capable of generating highly deleterious effects in the different compartments of the ecosystem is made necessary to know the magnitude and scope of the toxic potential they possess each of these residues in different biotic levels and environmental spheres impinging on. To achieve this purpose, samples were collected twice a week for a period of three months after which we proceeded to design a critical path that enabled ecotoxicological evaluation of these pollutants using experimental biomodels representative environments affected. The effect caused by waste generated in the service stations Manta on microflora and animals impacted soils, and to the same extent the damages were determined that these contaminants generated on the germination of plants representing of impacted ecosystems. For the processing, analysis and discussion of the results, a non- experimental design and statistical programs longitudinal aided by appropriate professionals experimental designs. The conclusion of the study makes clear the damage they cause to the ecosystem petrolizados waste generated in the service stations, from which you should create managements plans in each of the service stations, designed to minimize the impact cause on the environment as contaminants generated in them.
