Utilizing such waste to prepare geopolymers represents a prevalent approach to resource recycling, offering promising applications in pollution adsorption and construction materials. This review delves into recent advancements in synthesizing industrial solid waste-based geopolymers (ISWGs) and scrutinizes their diverse functional attributes, such as compressive strength, porosity, water uptake, among others. Furthermore, it expounds upon the formation mechanisms of ISWGs derived from dual systems: (Si+Al) and (Si+Ca), furnishing fresh insights into the underlying mechanisms governing ISWGs. Notably, the study gives particular attention to the frost behavior during the fabrication of ISWGs, an aspect that is pivotal for the sustainable development of these materials.

During batch experiments at low pH and [NOM], adsorption behaviors of COOH- and PhOH-rich compounds were similar. At low [NaCl] and high pH or [NOM], the adsorption of NOM decreased, with a preferential adsorption of PhOH over COOH-rich compounds. This can be ascribed to the surface site saturation and competition between COOH, PhOH and OH⁻ for surface binding, combined with electrostatic effects. Higher [NaCl], which was previously shown to favor NOM-NOM interactions at mineral surface, led to increased adsorption of COOH, while the adsorption of PhOH was not affected. Under flow-through conditions, multiple-binding-site mechanism was shown to control the fractionation of PhOH- and COOH-rich compounds.

We developed modular moving bed constructed wetlands (MMB-CWs) by integrating biofilm method into CWs through specialized design and achieved satisfactory N removal under ambient condition. Evaluating the N removal performance of MMB-CWs at low temperature is crucial for promoting CWs in cold climates. This study investigated the N removal performances of MMB-CWs and the variations of core functional genera at low temperature. Results indicated that the MMB-CW with a 60 % substrate filling rate achieved the highest N removal efficiency of 68.6 %, exceeding horizontal subsurface flow CW by 19.5 % (p &lt; 0.05). The incorporation of vertical baffles and partial substrate filling optimized the distribution and concentration of dissolved oxygen. Although microbial community in the MMB-CW experienced a decline in microbial richness and diversity, N-transforming genera became more concentrated. Proteobacteria increased significantly from 46.6 % to 69.0 % (p &lt; 0.05) as temperature decreased, in which the denitrifying genera including <em>unclassified_f__Comamonadaceae</em>, <em>Hydrogenophaga</em> and <em>Acinetobacter</em> increased significantly (p &lt; 0.05) and dominated the N removal process. The distribution of N-transforming functional genes suggested that denitrification was the primary pathway for N removal at low temperature, while anaerobic ammonium oxidation played a pivotal role as well. The findings reveal the mechanism by which the MMB-CW enhance N removal in low C/N wastewater at low temperature, providing strategy and theoretical support for improving the N removal performance of CWs in response to low temperature stress.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"276 ","pages":"Article 121507"},"PeriodicalIF":7.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the invasive snail <em>Sinotaia quadrata</em> as a potential tool for monitoring MPs pollution in freshwater ecosystems heavily impacted by human activities. Specifically, we examined whether the characteristics of MPs (i.e., shape, color, and chemical composition) found in water and sediment were reflected in those accumulated by <em>S. quadrata</em>, and whether MPs accumulation varied across different snail size classes. MPs were detected in all environmental matrices and snail samples, with fragments and filaments as the dominant shapes, blue, white, and black as the most common colors, and polypropylene, polyethylene, and polyethylene terephthalate as the primary polymers. A significant difference in MPs concentration per gram was found across snail size classes, with smaller snails accumulating more MPs than larger individuals, likely due to higher feeding rates during growth. A positive correlation was observed between snail shell length and weight, while MPs concentration per gram showed significant negative correlations with both parameters. These findings suggest that <em>S. quadrata</em> accumulates MPs from the environment, reflecting local contamination levels. While <em>S. quadrata</em> is an invasive species, this study demonstrates its potential utility in MPs monitoring, particularly in the context of eradication efforts. This approach integrates pollution assessment with invasive species management, offering a broader perspective on the role of biological invasions in environmental monitoring.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"276 ","pages":"Article 121513"},"PeriodicalIF":7.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, TCEP ability to promote (a) growth inhibition in algae, like the freshwater species Chlorococcum sp. and the saltwater species Tisochrysis lutea, (b) cytotoxic and oxidative stress-like events, such as Reactive Oxygen Species (ROS) formation and lipid peroxidation, in challenged mussel hemocytes, as well as (c) cytogenotoxicity in human lymphocytes, were investigated. Based on the results, environmentally relevant concentrations of TCEP could differentially affect the growth of both algal species, with the freshwater one (Chlorococcum sp.) to be more vulnerable compared to saltwater species Tisochrysis lutea. Accordingly, TCEP-treated mussel hemocytes showed increased levels of cell death and a concomitant enhancement of ROS generation and lipid peroxidation at most concentrations tested. Lastly, TCEP at concentrations tested showed significant cytogenotoxic effects on human lymphocytes, as revealed by the low Cytokinesis Block Proliferation Index (CBPI) values and the high micronuclei (MN) frequencies in challenged cells.
