Whilst ecology has served as a foundational inspiration for risk assessment in ecotoxicology, far less attention has been given to evolution, despite its importance. As the need for a new paradigm in ecotoxicology is becoming increasingly evident in the face of Global change, the consideration of evolutionary processes and patterns should provide a way to progress towards this objective. This review draws on the recent literature to support this idea, with a particular attention to the interplay between evolutionary rates. In doing so, we recast ecotoxicology as an innovative, exciting discipline, conceptually equipped to meet the challenges of the Anthropocene era.

Combined sewer overflow (CSO) discharges pose a significant challenge to urban water management. Constructed wetlands (CWs) are a promising blue-green infrastructure solution for CSO management and water quality improvement, with recognized economic, social, and environmental benefits. This review synthesizes the state-of-the-art in CSO treatment using CWs over the past 30 years and explores current trends and future projections. A bibliometric analysis of 68 papers from the Web of Science Core Collection revealed that although CWs have been applied at a full scale for CSO treatment since the 1990s, they remain an emerging research topic. Germany, France, Italy, the United Kingdom and the United States of America lead in literature production and application. However, there is a significant lack of information from the Global South (developing countries) and tropical/subtropical regions. Reports from temperate developed countries indicate good performance, with removal efficiencies above 70 % for conventional pollutants such as solids, organic matter, and nutrients (nitrogen and phosphorus). However, pathogen removal was limited. Contaminants of emerging concern such as pharmaceuticals, polycyclic aromatic hydrocarbons (PAHs), and microplastics, have also been investigated in CW-treated CSOs with divergent results. This review also discusses various aspects, including regulations, design, environmental performance, and trade-offs. While CWs demonstrate substantial potential for preventing surface water pollution, their application and associated knowledge must expand beyond developed temperate regions, mirroring the global adoption of CWs for domestic wastewater and stormwater treatment. This expansion is crucial for CWs to be considered a truly global solution for CSO treatment.
复合式污水溢流（CSO）排放对城市水管理提出了重大挑战。人工湿地（CWs）是一种很有前途的蓝绿色基础设施解决方案，用于公民社会组织的管理和水质改善，具有公认的经济、社会和环境效益。本综述综合了过去30年来使用化学武器治疗CSO的最新进展，并探讨了目前的趋势和未来的预测。对Web of Science核心合集68篇论文的文献计量分析表明，尽管自20世纪90年代以来，CWs已经全面应用于CSO治疗，但它们仍然是一个新兴的研究课题。德国、法国、意大利、英国和美国在文献生产和应用方面处于领先地位。然而，全球南方（发展中国家）和热带/亚热带地区的资料严重缺乏。来自温带发达国家的报告显示了良好的性能，对固体、有机物和营养物质（氮和磷）等常规污染物的去除效率超过70%。然而，病原菌的去除是有限的。新出现的关注污染物，如药物、多环芳烃（PAHs）和微塑料，也在化化水处理的公民社会组织中进行了研究，结果不同。本综述还讨论了各个方面，包括法规、设计、环境性能和权衡。虽然化粪池在防止地表水污染方面显示出巨大的潜力，但它们的应用和相关知识必须扩展到发达温带地区以外，反映出全球在生活废水和雨水处理中采用化粪池的情况。这一扩展对于将CWs视为CSO治疗的真正全球解决方案至关重要。

Constructed wetlands (CWs) have been demonstrated to be effective solution for treating winery wastewater (WWW). In this paper, worldwide experiences over the last 25 years of full-scale CWs for WWW treatment are gathered. In total, three CW types were identified: horizontal subsurface flow, vertical subsurface flow and hybrid CWs. The organic and hydraulic loading rate ranged between 15.74–315 gCODm−2d−1 and 13–313 mmd-1, respectively. The most common plant species were Phragmites australis, Typha spp., and Schoenoplectus tabernaemontani. In this review, treatment efficiency of CWs is presented as well as their operational challenges and opportunities.

Wildfires increasingly degrade source-water quality, yet the reactivity of fire-altered dissolved organic carbon (DOC) toward trihalomethane (THM) formation remains unclear. This mini-review synthesizes 14 paired pre/post-fire datasets under a carbon-normalized framework (THM-specific formation potential, THM-SFP). (i) Occurrence: most studies show lower THM-SFP after fire from loss of oxygen-rich moieties. (ii) Severity: moderate burning can produce phenolic/carbonyl fragments, elevating THM-SFP, whereas high severity suppresses it. (iii) Rainfall: first flushes raise DOC and bulk THMs, while THM-SFP responses are mixed. Cross-study interpretation remains constrained by methodological heterogeneity and limited data. Findings support severity-stratified, time-resolved monitoring for post-fire water management.

Effect-based methods (EBM) are increasingly used to assess disinfected water quality as they can detect the mixture effects of all bioactive chemicals, including disinfection by-products (DBPs). In this review, we discuss the application of EBM to extracts of disinfected water, with bioassays for cytotoxicity, genotoxicity and oxidative stress response being the most responsive to DBPs. The contribution of known DBPs to the mixture effect can be predicted from single DBPs’ effects using established mixture models. Regulated DBPs typically have a minor contribution to the observed effect. Effect-based trigger values can be used to determine if the treated water quality is acceptable.

Peracetic acid (PAA), an organic compound with the formula CH3CO3H, and a sterilant and disinfectant, has emerged as a promising alternative to free chlorine for achieving high-level disinfection in combined sewer overflow, wastewater, and stormwater. However, a major concern with any water disinfectant is its potential to react with natural organic matter or other constituents, leading to the unintentional formation of disinfection byproducts (DBPs). This review examines DBP formation during PAA disinfection and PAA-based advanced oxidation processes (AOPs), with an emphasis on studies published within the past five years. It summarizes the influence of halides, nitrite, and various AOP operational conditions on DBP formation. Additionally, it explores the mechanisms of DBP formation in the presence of halides during PAA disinfection, highlighting key intermediates involved in the reactions. The insights provided in this review offer valuable guidance for minimizing DBP formation in further applications of PAA in water treatment.

The proliferation of algal blooms in freshwater is a water quality concern. Algae release algal organic matter (AOM) that is a disinfection byproduct (DBP) precursor. Monitoring blooms remains challenging as cell concentration and diversity vary across seasons and locations. Compared to natural organic matter (NOM), AOM has distinct characteristics. The low aromaticity and high nitrogen content of AOM favor unregulated nitrogen-containing DBPs, such as haloacetonitriles and haloacetamides, over regulated trihalomethanes, and haloacetic acids. Research utilizing ultra-high-resolution mass spectrometry found that AOM is an important precursor of >2-carbon DBPs. With prevalent fatty acids and peptides, studies have identified chlorinated biomolecule formation from AOM.

Disinfection byproducts (DBPs) are ubiquitous contaminants in drinking water that are formed through reactions between disinfectants and natural or anthropogenic precursors. While regulatory and research efforts have historically focused on 1–2 carbon DBPs, these compounds account for only a fraction of the total organic halogen and measured toxicity in finished drinking water. Recent research has shifted attention to higher-carbon DBPs with >2-carbon atoms (>C2 DBPs). We summarize recent advancements in the discovery, occurrence, and formation mechanisms of >C2 DBPs and highlight the need to integrate >C2 DBPs into toxicity frameworks to better assess their contribution to the overall toxicity of disinfected waters.

Constructed wetlands are a promising arsenic removal technology. Laboratory-scale experiments have proved their arsenic removal capacity and identified the main factors affecting it. However, very few pilot and full-scale systems are reported. Most of the recent studies report on laboratory-scale systems operated during short periods, therefore lifespan, seasonal effects, and the long-term effects of vegetation cannot be evaluated. Recent work on mechanistic models could guide the development of design guidelines, which are not currently available. Confirming laboratory-scale results in pilot and full-scale systems remains a challenge, as well as the use of their data for future calibration and validation of models.

Pesticides widely used in agriculture and households pose environmental risks due to their persistence, toxicity, and bioaccumulative nature. Constructed wetlands (CWs) have emerged as a sustainable solution for removing pesticides from agricultural runoff and wastewater. Their performance depends on factors like plant species, substrate, wastewater composition, climate, and retention time. Key challenges include seasonal performance variability, substrate clogging, and pesticide accumulation in sediments. Full-scale studies show removal rates from 38% to over 99%, influenced by pH, temperature, vegetation, microbial activity, and retention time. Emerging strategies, such as solar photocatalytic oxidation and real-time monitoring, offer promising enhancements to CW functionality, supporting sustainable and environmentally friendly water treatment solutions.
