“…Although the presence of chromium was minimal, it can still affect the efficiency of nutrient elimination. Heavy metals like chromium can inhibit root oxygenation and seriously impact the elimination of nitrogen and phosphorus 35 – 37 . To ensure effective treatment, it is important to separate domestic wastewater from industrial wastewater 38 , 39 .…”

Colombia’s continuous contamination of water resources and the low alternatives to produce biofuels have affected the fulfillment of the objectives of sustainable development, deteriorating the environment and affecting the economic productivity of this country. Due to this reality, projects on environmental and economic sustainability, phytoremediation, and the production of biofuels such as ethanol and hydrogen were combined. The objective of this article was to design and develop a sustainable system for wastewater treatment and the generation of biofuels based on the biomass of the aquatic plant Eichhornia crassipes. A system that simulates an artificial wetland with live E. crassipes plants was designed and developed, removing organic matter contaminants; subsequently, and continuing the sustainability project, bioreactors were designed, adapted, and started up to produce bioethanol and biohydrogen with the hydrolyzed biomass used in the phytoremediation process, generating around 12 g/L of bioethanol and around 81 ml H2/g. The proposed research strategy suggests combining two sustainable methods, bioremediation and biofuel production, to preserve the natural beauty of water systems and their surroundings.

“…During bioaccumulation, macrophytes store the polluting elements in their roots or transmit them to the shoots [14]. The tissue of the submerged parts allows the expansion of the surface area for the development of microbial community biofilm and promotes the release of oxygen, increasing degradation, in addition to nutrient absorption [39].…”

“…Water pollution by organic and inorganic contaminants represents a current challenge, and the attempt to remove these elements is the object of study of different studies [4]. Several pollutants have recently been analyzed in the literature for their remediation by biological agents, such as pharmaceuticals and cosmetics [5]; polycyclic aromatic hydrocarbons [6]; artificial chemicals [7]; microplastics [8]; agrochemicals and pesticides [9]; primary nutrients [10]; HM [8,[11][12][13][14][15].…”

Bioremediation of Aquatic Environments Contaminated with Heavy Metals: A Review of Mechanisms, Solutions and Perspectives

The degradation of water resources is related to anthropic actions such as rapid urbanization and industrial and agricultural activities with inefficient land use and occupation management. Water pollution caused by organic and inorganic contaminants represents a current challenge for researchers and humanity. One of the techniques used to remove pollutants from aquatic environments is bioremediation, through the metabolism of living organisms, and especially phytoremediation, with plants as a decontamination agent. Aiming to demonstrate the current mechanisms, solutions, and perspectives regarding bioremediation, and especially phytoremediation in aquatic environments, a literature review was conducted, highlighting the following subjects: heavy metals as contaminants, phytoremediation, evaluation of resistance mechanisms, removal of heavy metals by microorganisms and biofilters of the artificial floating islands type. From the literature research carried out, it can be concluded that alternatives such as macrophyte plants have proved to be an effective and efficient alternative with a high potential for removal of contaminants in aquatic environments, including concomitantly with microorganisms. There was no mechanism well-defined for specific absorption of heavy metals by plants; however, some results can indicate that if there was sporadic contamination with some contaminants, the plants can be indicators with some adsorption and absorption, even with low concentration in the watercourse by the moment of the evaluation. It is necessary to study bioremediation methods, resistance mechanisms, tolerance, and removal efficiencies for each biological agent chosen. Within the bioremediation processes of aquatic environments, the use of macrophyte plants with a high capacity for phytoremediation of metals, used combined with bioremediating microorganisms, such as biofilters, is an interesting perspective to remove contaminants.

“…Macrophytes play an important role in structuring aquatic environments, especially those of lentic type, since their presence in these ecosystems increases the complexity of the habitat, significantly influencing aspects such as diversity, distribution, richness, and abundance of the aquatic macroinvertebrates (Heisi et al 2023). These plants increase the structural heterogeneity of macroinvertebrates by providing refuges against predators (Misteli et al 2022), offering food for herbivores and detritivores, (Fontanarrosa et al 2013) and providing spaces that facilitate emergence and oviposition (Walker et al 2013).…”

Las macrófitas acuáticas juegan un rol importante en los sistemas lénticos, ya que constituyen el hábitat particular de varios grupos de insectos acuáticos y desempeñan un papel fundamental en la estructuración de sus comunidades. El objetivo de este estudio fue contribuir al conocimiento de la entomofauna acuática asociada las macrófitas en ciénagas de la cuenca media del Río Atrato, Chocó-Colombia. Durante cuatro meses se hicieron colectas de insectos acuáticos asociados a las raíces de diferentes plantas acuáticas, utilizando un cuadrante de un m2, dotado de una malla de 0,5 mm, con tres replicas por ciénaga. Simultáneamente se midieron algunas variables físicas y químicas del agua. La comunidad de insectos acuáticos estuvo compuesta por 6 órdenes, 23 familias y 36 géneros. Los órdenes más representativos fueron Hemiptera (Heteroptera) y Odonata y las familias más abundantes fueron Noteridae (Coleoptera) y Libellulidae (Odonata). El índice de diversidad presentó un rango de entre 2,39 y 2,07 bits/ind, sobresaliendo la ciénaga Plaza Seca, mientras que la dominancia estuvo entre 0,16 y 0,11. El grupo funcional de mayor abundancia fue el de los predadores. Las variables pH, temperatura del agua y transparencia presentaron diferencias significativas entre ciénagas y existieron importantes asociaciones entre la entomofauna acuática y las variables abióticas analizadas.
