Constructed wetlands (CWs) primarily achieve efficient wastewater purification through synergistic interactions among substrates, plants, and microorganisms. Serving as the structural foundation of entire wetland system, substrates not only provide a growth medium for but also serve adhesive carriers microorganisms habitats animal activities. Research on has attracted considerable attention; however, in practical engineering applications, selection often depend personal experience, which may lead to significant gaps effectiveness systems treating different characteristic contaminants. Therefore, it is great significance investigate influence removal contaminants sewage identify substrate materials with good physical chemical properties optimize design operation CWs-based sewage-treatment improve their efficiency. In this review, bibliometric analysis was conducted using Web Science database VOSviewer_1.6.20 software assess progress research CWs. This article provides comprehensive overview types characteristics based recent advancements field. Additionally, discusses methods factors related conventional (COD, nitrogen, phosphorus), heavy metals (HMs), fluorinated compounds, pharmaceuticals, care products (PPCPs), microplastics. A thorough evaluation economic costs various ability remove major from water bodies, providing reference further development technology.

To explore the contamination status and identify source of heavy metals in sediments major inflow rivers Dianchi Lake China, sediment samples were collected analyzed. Specifically, distribution, source, water quality, health risk assessment analyzed using correlation analysis (CA), principal component (PCA), metal factor (Cf), pollution load index (PLI), potential ecological (PERI). Additionally, chemical fractions for mobility characteristics. The results indicate that average concentration ranked descending order Zn > Cr Cu Pb As Ni Cd Hg, most elements existed less-mobile forms. Cfwas Hg Ni; accumulation Zn, Cd, was obvious. Although spatial variability contents pronounced, synthetical evaluation PLI PERI both reached a high level.

The Tocantins-Araguaia basin is one of South America's largest river systems, across three Brazilian states (Maranhão, Tocantins, and Pará), within the Legal Amazon region. Despite draining extensive Cerrado savanna rainforest ecosystems, it has suffered significant degradation, notably in past 40 years. Human activities, including agricultural expansion, deforestation, introduction non-native species, have worsened environmental damage, which alarming since many residents villages along middle Tocantins River rely on for water supply, recreation, fishing. This study assessed concentration potentially toxic essential elements samples from four sampling sites distributed River. monitoring occurred throughout 2023, involving measurement parameters both on-site laboratory. Water quality its health implications were evaluated using Weighted Arithmetic Quality Index (WAWQI), (WQI), risk assessment index. levels aluminum, copper, iron, magnesium, selenium exceeded legal standards. Seasonal fluctuations indicate a complex dynamic influenced by climatic or seasonal factors, with February showing highest values. Site P1, located urban areas, exhibited elevated mean concentrations conductivity, total dissolved solids (TDS), chlorophyll, indicating need continuous monitoring. nitrogen at P1 raise concerns regarding drinking quality, concern region's who use untreated water. variations element concentrations, overall WAWQI categorized all sections as "Excellent," WQI rated "Good." assessments detected no risks, but interventions are crucial sustained improvement.
