“…12). Although the Dilúvio Stream is located below the Jacuí Delta and it has a much lower water discharge than the four tributaries evaluated in the present study, it is an urban river highly impacted by heavy pollution with metals and phosphorus resulting from anthropogenic activities (Maggioni dos Santos et al, 2021). The Dilúvio Stream catchment has been polluted by several sources, including unplanned land development, discharge of untreated sewage and dense road traffic.…”

“…The Dilúvio Stream catchment has been polluted by several sources, including unplanned land development, discharge of untreated sewage and dense road traffic. Furthermore, this river is devoid of riparian forest along most of its course, and in the lowest 12 km section, the stream has been channeled, which increases the contribution of surface runoff from the catchment and the associated input of road-derived contaminants (Maggioni dos Santos et al, 2021). Accordingly, although the sediment contribution of the Dilúvio Stream to Lake Guaíba is likely to be low, it may supply a large number of pollutants that should be explicitly considered in future research.…”

“…However, as they grow and utilize this natural resource, large loadings of contaminants, such as those associated with domestic and industrial sewage, are frequently generated and released into waterbodies. As a consequence, it is common to observe contamination of water bodies with heavy metals that are harmful to human and environmental health (Maggioni dos Santos et al, 2021). Moreover, the increasing occurrence of algal blooms, due to excessive inputs of phosphorus, have attracted worldwide attention, because they seriously affect aquatic life, local landscapes, tourism, and drinking water supplies (Duquesne et al, 2021;Mu et al, 2021).…”

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.

“…Heavy metal poisoning of soil is a global concern that threatens both the production of safe food and human health. Apart from exceptional geogenic causes, anthropogenic activities such as mining, smelting, combat and military training, e-waste, burning fossil fuels, improper waste disposal, unauthorized use of agrochemicals, and irrigation unintentionally release heavy metal pollutants into the soil [1][2][3]. Heavy metal contamination is commonly caused by improperly disposing of mine waste, industrial waste, and building trash in the soil.…”

Effect Of Phytoremediation On The Geotechnical Properties Of Heavy Metal Contaminated Soil

<p>The accumulation of heavy metals in soils increases rapidly due to various natural processes. Heavy metal pollution changes the geotechnical properties of soil and poses a serious threat to human health and ecosystems, so soil pollution remediation is particularly important. Phytoremediation is an environmentally friendly approach that can be used as a successful mitigation measure to restore heavy metal-contaminated soils cost-effectively. The plants extract and remove elemental contaminants or reduce their bioavailability in soil and improve the geotechnical properties. In this study, we are conducting a pot experiment with Amaranthus by adding Zn salt as a contaminant and determining the rate of removal of metal.</p>
