The heavy metals (HMs) and metalloids such as Cr(VI), As(Ill), Pb(II) in contaminated water are toxic even at trace levels have caused devastating negative health impacts on human beings. Hence, the effective adsorption of these from is important to protect biodiversity, hydrosphere ecosystems, In this study, a leachate modular tower (LMT) was developed for singular purpose adsorbing HMs. LMT contained nano-slag liner, which synthesized slag. blended different proportions 90:10; 80:20, 70:30, 60:40, 50:50 combined mass clay nano-slag, evaluate most efficient ratio blends capable HMs with 100% efficiency. A series tests were performed capacity embedded liners. Attenuation periods 2, 5, 7, 10 days temperature 500 °C also selected improve sorption rate uptake Subsequently, effluents subjected inductive coupled plasma spectrometry (ICP-MS) concentrations percentages adsorbed HMs, calculated using pseudo-first-order model. results revealed that removal 98%As, 99%Cd, 99.9% Pb achieved 50%:50% soil liner equilibrium period. Furthermore, 98%Zn, 95.45%Cu, 93.3%Fe, 97%Ni, 89% Hg upon further investigation same dosage conditions. scanning electron microscopy (SEM) demonstrated some traces absorbed found surfaces, indicating significant changes microstructure. indicated increased significantly due elevated temperature, aluminosilicate structure, prolonged attenuation period, associated an pH level higher cation exchange (CEC), liner.

Abstract Gadolinium‐based contrast agents (GBCAs) have revolutionized medical imaging, enhancing the accuracy and diagnostic value of magnetic resonance imaging (MRI). The increasing use GBCAs has raised concerns about release gadolinium (Gd)(III) into environment potential risks for human health. Initially, multiple administrations were associated only with nephrogenic system fibrosis disease in individuals impaired kidney function. Even if Gd(III) retention tissues not yet been correlated any specific disease, caution is required extensive GBCAs. related to employment GBCAs, due possible deposition retention, should be extended also healthy without renal impairments. To ensure well‐being patients, there a need develop even more stable better‐performing new MRI approaches requiring lower doses and, finally, innovative methods recovering from both patients’ urines environment. This can strong advantages health environmental sustainability, considering scarcity, being rare earth element, shared guideline reduce, as much possible, metals.

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

The application of ornamental plants in constructed wetlands (CW) is increasingly interest to researchers, professionals actively involved wetland management and/or wastewater treatment (WWT), so it necessary know the trends this field research. objective study was develop a scientometric on use CWs for WWT during period 2002–2022. For this, search information carried out Scopus database, including all articles and reviews related field. analysis recovered documents allowed key aspects evolution production recent years, maturity research field, identify most used therefore gaps. Likewise, possible countries, relevant authors, main journals cited through which knowledge area disseminated. results showed that Mexico, Brazil, USA, China India have highest number publications CWs. It found are Canna, Iris, Heliconia Zantedeschia. This can help researchers new approaches concluded has aroused great since 2002; however, more still be with cold climates, influence substrate growth these plants.

Global demand for freshwater is rapidly escalating. It highly essential to keep pace with the necessities of increasing population. The effluents wastewater are gradually identified as a reservoir resources energy generation and economic boom. Henceforth, most sludge have great potential reuse recycling. re-utilization valorization contribute accomplishing sustainable development goals, combating water scarcity, alleviating adverse environmental impacts on components. present article highlights novel approaches treatment waste different industrial origins value-added products recovery biopolymers, vitamins, enzymes, dyes, pigments, phenolic compounds. We highlighted life cycle assessment techno-economic analysis. In addition, we addressed critical overview barriers large-scale application resource strategies economic, environmental, social concerns associated using waste-derived products.

Abstract The 2030 Agenda, established in 2015, contains seventeen Sustainable Development Goals (SDGs) aimed at addressing global challenges. SDG-06, focused on clean water, drives the increase basic sanitation coverage, management of wastewater discharges, and water quality. Wastewater treatment could contribute to achieving 11 17 SDGs. For this purpose, phytoremediation is a low-cost adaptable alternative reduction control aquatic pollutants. objective study highlight role macrophytes removal degradation these compounds, focusing Eichhornia crassipes (Mart.) Solms, commonly known as hyacinth. reported values indicate that plant has capacity over 70% for metals such copper, aluminum, lead, mercury, cadmium, metalloids arsenic. Additionally, it significantly improves quality parameters turbidity, suspended solids, pH, dissolved oxygen, color. It also reduces presence phosphates, nitrogen compounds below 50%. plays significant organic contaminants pesticides, pharmaceuticals, dyes. This describes several valuable by-products from biomass hyacinth, including animal fish feed, energy generation (such briquettes), ethanol, biogas, composting. According analysis carried out, E. great phytoremediation, which makes viable solution management, with potential ecosystem restoration. Graphical abstract

Pharmaceutical waste disposal is a significant problem for the global healthcare system. It poses threat to water safety, which already challenge as 1 out of 3 people still lack access safe drinking water. We conducted thorough literature review relevant articles published between 2000 and 2023. Our scrutinized 107 studies, each applied pre-set inclusion exclusion criteria ensure high-quality research. The focus our interest was on health risks posed by pharmaceutical compounds in waste. also evaluated recycling methods proposed practical measures proper education implementation strict legislation address this issue. have been found resources worldwide. These can negative effects multiple organs it's important remove them from resources. However, quality varies globally due limitations accessibility budget purification efforts. Comprehensive studies are needed identify water's most common residues develop effective removal strategies. Proper pharmaceuticals crucial protect clean This requires raising awareness, educating public population, implementing regulations, collaborating among stakeholders.
