Gases invernadero en aguas con bajo oxígeno en el reservorio eutrófico de Prado (Colombia)

Maribeb Castro - González, Victoria Torres-Valdés

Resumen


En esta investigación se cuantificó la concentración de gases invernadero (metano y óxido nitroso) y de otros parámetros fisicoquímicos en la columna de agua del reservorio eutrófico de Prado para determinar con experimentos in situ el origen del óxido nitroso y la distribución vertical de ambos gases. Los resultados indicaron que la nitrificación contribuyó más activamente que la desnitrificación a la producción de óxido nitroso en la columna de agua, con tasas estimadas en 122,5 ± 79,9 nM/d, y que comparado con otras hidroeléctricas y lagos en el mundo, las concentraciones de óxido nitroso (de hasta 38,6 ± 0,9 nM) y de metano (de hasta 242 ± 85,5 μM) cuantificadas en el embalse fueron altas. Este es el primer estudio desarrollado en la represa de Prado que muestra la sobresaturación de ambos gases en la columna de agua, lo que sugiere que esta hidroeléctrica podría estar emitiendo cantidades significativas de gases invernadero a la atmósfera. © Acad.
