Abstract: | La eutrofícación de un cuerpo de agua es proceso de crecimiento masivo de algas y
macrófitas acuáticas que reducen la concentración de oxigeno disuelto en el agua. Este
fenómeno que puede tener origen natural, es incrementado notablemente por el aporte de
nutrientes de origen antropogénico.
Para determinar el estado trófico de la laguna de Límoncocha, se realizaron
mediciones del contenido de fósforo total en el agua de 6 puntos en la laguna y en dos
puntos adicionales que corresponden a los dos principales afluentes (río Pishira y río
Playayacu) que tiene la laguna.
Los resultados arrojan valores promedio de fósforo total de 75 mg/m3 para la
laguna, de 144 mg/m3 para el río Playayacu y 56 mg/m3 para el río Pishira.
Estos valores se comparan con los datos del sistema de clasificación del estado
trófico para fósforo total (índice de Salas, Martinó 1990).
De acuerdo a esto la Laguna de Límoncocha se encuentra en un estado mesotrófico. The eutrophication of a body of water is a process of massive growth of algae and aquatic macrophytes that reduce the concentration of dissolved oxygen in water. East phenomenon that may have a natural origin, is significantly increased by the contribution of nutrients of anthropogenic origin. To determine the trophic status of the lagoon of Límoncocha, measurements of the total phosphorus content in the water of 6 points in the lagoon and in two additional points corresponding to the two main tributaries (river Pishira and river Playayacu) that has the lagoon. The results show average values of total phosphorus of 75 mg / m3 for the lagoon, of 144 mg / m3 for the Playayacu River and 56 mg / m3 for the Pishira River. These values are compared with the data of the state classification system trophic for total phosphorus (Salas index, Martinó 1990). According to this, the Laguna de Límoncocha is in a mesotrophic state.
