Eficacia de dos especies de macrofitas fitorremediadoras (eichornia crassipes –buchón de agua y lemna minor –lenteja de agua) en bioensayos con aguas residuales del Lago Balmoral Urbano, Villavicencio

Abstract

El déficit de fuentes de agua limpias dada la presencia de contaminantes en el agua es una problemática ambiental no solo de nivel local, sino también regional y nacional en Colombia. Para contrarestar este problema, se han implementado diferentes sistemas de tratamiento de aguas incluyendo la fitoremediación. La intención de este estudio fue la de evaluar la capacidad fitoremediadora de dos especies de plantas acuáticas –Eichornia crassipes y Lemna minor – para remover dos contaminantes –nitrógeno amoniacal N-NH3 y hierro total Fe – a partir de aguas residuales del lago Balmoral producto de la actividad agroforestal y ganadera en áreas vecinas. A partir de muestras de agua residual, se realizó el montaje de 2 bioensayos, uno con 100 g de E. crassipes y otro con 20 g de L.minor, y se realizaron mediciones de los dos contaminantes cada 4-5 días por espacio de 1 mes. Adicionalmente, se estableció el grado de absorción de los 2 contaminantes a partir de la raíz de E. crassipes y hojas de L. minor por medio de la maceración de las partes de las plantas al inicio y al final de los bioensayos. Los resultados obtenidos resaltan en Eichornia crassipes su capacidad de absorción y acumulación de contaminantes (56.5% de N-NH3 y 47.1% de Fe total), y su alta reducción y remoción en el agua residual (95% de N-NH3 y 75.9% de Fe Total). Por el contrario, Lemna minor no fue en este estudio una planta eficiente en la reducción y remoción de contaminantes del agua residual (0.45% de N-NH3 y 45% de Fe total), con baja capacidad de bioacumulación (26.7% de N-NH3 y 11.3% de Fe total). Se destaca la alta capacidad fitoremediadora de E. crassipes similar a la reportada en otros estudios. Se realizan algunas recomendaciones para la implementación de un sistema de fitoremediación con macrófitas acuáticas en el lago Balmoral.

The deficit of clean water sources due to the presence of contaminants in the water is an environmental problem not only at the local level, but also at the regional and national level in Colombia. To counteract this problem, different water treatment systems have been implemented, including phytoremediation. The intention of this study was to evaluate the phytoremediation capacity of two species of aquatic plants – Eichornia crassipes and Lemna minor – to remove two contaminants –ammoniacal nitrogen N-NH3 and total iron Fe – from Balmoral Lake wastewater, product of agroforestry and livestock activity in neighboring areas. From residual water samples, 2 bioassays were set up, one with 100 g of E. crassipes and the other with 20 g of L. minor, and measurements of the two contaminants were made every 4-5 days for a period of 1 month. Additionally, the degree of absorption of the 2 contaminants from the root of E. crassipes and leaves of L. minor was established by maceration of the plant parts at the beginning and at the end of the bioassays. The results obtained highlight in Eichornia crassipes its capacity for absorption and accumulation of pollutants (56.5% of N-NH3 and 47.1% of total Fe), and its high reduction and removal in wastewater (95% of N-NH3 and 75.9% Total Fe). On the contrary, Lemna minor was not in this study an efficient plant in the reduction and removal of pollutants from wastewater (0.45% of N-NH3 and 45% of total Fe), with low bioaccumulation capacity (26.7% of N- NH3 and 11.3% of total Fe). The high phytoremediation capacity of E. crassipes is outstanding, which is similar to that reported in other studies. Some recommendations are made for the implementation of a phytoremediation system with aquatic macrophytes in Lake Balmoral.
