“…Depending on the pollutant properties, organics may be degraded in the roots zone through the plant stimulation of microbial activity (phytostimulation or rhizodegradation) or by direct uptake by the plant, followed by degradation within their tissues via their own enzymatic activities (phytodegradation) and sequestration (in vacuoles or bound to insoluble cellular structures) or volatilization [24][25][26][27][28]73,[91][92][93][94].…”

“…Phytotechnologies have been successfully used for removal of many organic xenobiotics from contaminated soils, waters and wastewaters [21,[24][25][26][27][28][29][30][31][32][33]. This type of approach attempts to exploit the ability of plants to adsorb, uptake and concentrate or metabolize organic xenobiotics, as well as to release root exudates that enhance biotransformation and microbial degradation of those organics.…”

“…1 Scheme of the experimental setup biologically-based wastewater treatment systems (Macek et al 2000;Zhang et al 2010). Figure 2a and b show that after 10 days of incubation, almost complete elimination was obtained for both ACAPh and CAFF in all reactors filled with secondary-treated wastewater.…”

The presence of pharmaceuticals and endocrine-disrupting chemicals (EDCs) in wastewater treatment plant effluents is an issue of great concern due to the negative effects that these compounds may have on human health and ecosystems. The present study aims to assess the capacity of two aquatic plants (Lemna sp. and Spirogyra sp.), commonly found in polishing ponds, for removing six pharmaceutical compounds (diclofenac, acetaminophen, ibuprofen, carbamazepine, clofibric acid, and propranolol), two EDCs (17a-ethinylestradiol and bisphenol A), and one stimulant (caffeine) under laboratory-scale conditions. Planted and unplanted reactors fed with secondary-treated wastewater or ultrapure water in both covered and uncovered conditions were studied. The highest removal efficiencies, which ranged from 31 to 100 %, were achieved in uncovered planted systems containing secondary-treated wastewater after 20 days of incubation. The results demonstrated that non-charged compounds with a log Kow between 2 and 4 were affected by the presence of vegetation, probably due to their plant uptake, whereas negatively charged compounds were not. This highlights that the presence of plants in polishing ponds plays an important role in the removal of pharmaceuticals and EDCs.

2.7 billion people, and the volume of water will have to increase 41% to meet the needs of the population [7]. In poor countries, the problems are more alarming in relation to untreated wastewater [10].Even though most of the farm households are aware of the environmental and health consequences related to the crop irrigation with wastewater, they still use it because of its cost advantages. This issue is one of the sanitary challenges also found at water-scarce regions [11]. This practice is widely used in Africa; for example, in [12] observed that wastewater treatment systems do not always reach enough quality for the purposes of irrigation and for non-potable applications. Therefore, water reuse might be dangerous for the farmers in some regions. . The results also showed that CWs system is suitable for removing ions from the wastewater. Cation and anion monitoring in a wastewater treatment pilot project RESUMEN:El propósito del tratamiento de aguas residuales es la reutilización del agua.Esta reduce el consumo de agua potable y previene la contaminación del agua de primer uso. La reutilización del agua ya se ha implementado con éxito en diferentes lugares. Los tratamientos que utilizan los humedales artifi ciales son ampliamente estudiados como una alternativa más económica y ecológica para tratar las aguas residuales. En estos sistemas, el control de especies inorgánicas también es importante. Este estudio ha monitoreado cationes (Na + . Los resultados también mostraron que el sistema CWs está adecuado para la eliminación de iones del agua residual.,
