A network analysis of SCOPUS data revealed significant knowledge gaps, especially concerning the fate of LCMs in WWTPs.

Advanced treatment techniques such as UV/peroxydisulfate (UV/PDS) showed removal rates of 77–84% for LCMs with biphenyl and ethoxy groups. These groups alter electron distribution, making the molecules more susceptible to oxidative attack by reactive species such as hydroxyl and sulfate radicals.

However, some degradation intermediates formed are toxic, necessitating further research of the treatment processes.</p><h3>Summary</h3><p>This review underscores the need for systematic monitoring of LCMs in wastewater and their transformation products in treated wastewater and sludge, alongside advancements in treatment technologies to mitigate environmental and health risks.

Since most drinking water treatment systems are ineffective in removing these contaminants, addressing this issue requires a multi-faceted approach such as source identification, control using green infrastructure, advanced treatment technologies, public awareness and amending regulatory frameworks. Working towards that requires an in-depth understanding of the previous and ongoing research on categories of CECs, and new-age sustainable removal techniques that include nature-based removal systems (NBS). This paper aims to (1) identify and categorize the direct and indirect sources of CECs, (2) evaluate the effectiveness of existing legislative measures, (3) various CECs treatment/removal technologies and analyze the factors affecting treatment technologies, (4) highlight challenges and advancements and (5) propose recommendations for future research and policy development. Ultimately, this review aims to contribute to the development of more effective and sustainable strategies for managing CECs, ensuring better protection of environmental and public health. &lt;/p&gt;&lt;h3&gt;Recent Findings&lt;/h3&gt;&lt;p&gt;The reviewed articles detail global efforts to eradicate CECs from the environment. These efforts include creating priority lists of chemicals that need to be removed, tailored to their usage in specific countries. For instance, Australia employs a tool called ECHIDNA, which aids in prioritizing and categorizing harmful chemicals that could disrupt the environment. After identifying these chemicals, various methods are then employed to treat water and remove the CECs effectively. NBS can be considered a sustainable yet efficient treatment solution for the removal of CECs from the urban stormwater sink. Constructed wetlands (CWs) are considered to be one of the most effective NBS for water treatment and CECs control in the aquatic environment. Key removal processes involved are sorption, photodegradation, microbial biodegradation and phytoremediation. Factors such as hydrology, substrate, vegetation, Log (Kow), structure of the CEC compounds, water polarity of the chemicals to be removed, presence of electron-donating groups and natural organic matter influence these removal mechanisms. A comparative study of various methods for eliminating CECs of various categories from water demonstrates that CWs are particularly notable, achieving an impressive 88% removal efficiency. This high efficiency, combined with their low operational and maintenance costs, makes them an attractive option for water treatment, in both developed and developing regions. CWs are highly effective in reducing pollution, with their cost-effectiveness being directly linked to their pollutant removal capabilities. &lt;/p&gt;&lt;h3&gt;Summary&lt;/h3&gt;&lt;p&gt;Investing in the research and development ","PeriodicalId":528,"journal":{"name":"Current Pollution Reports","volume":"11 1","pages":""},"PeriodicalIF":8.1,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40726-025-00357-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, prolonged exposure leads to detrimental effects, including light attenuation from algal blooms, ammonium toxicity impairing electron transport rates, and competitive exclusion by fast-growing algae. Species-specific tolerance varies significantly: resilient seagrasses like <i>Halodule wrightii</i> upregulate antioxidant enzymes (e.g., superoxide dismutase and catalase) and accumulate non-enzymatic flavonoids to mitigate oxidative stress, while sensitive species such as <i>Syringodium filiforme</i> suffer metabolic imbalances and biomass loss. Adaptive mechanisms span multiple scales. At the molecular level, stress-responsive transcription factors (e.g., <i>WRKY </i>transcription factor gene and <i>MYB </i>proto-oncogene transcription factor gene) regulate antioxidant and carbon metabolism genes in <i>Posidonia oceanica</i> under nutrient excess. Physiologically, seagrasses reallocate carbon to belowground tissues under shading and suppress algal competitors via allelochemicals. Ecologically, herbivory-mediated algal control indirectly reduces oxidative stress. Despite these adaptations, chronic eutrophication degrades ecosystem services and destabilizes fishery habitats.</p><h3>Summary</h3><p>This review summarized the stress responses and adaptive mechanisms of seagrass under eutrophication.

Despite this, agriculture has historically been underrepresented in air quality management and climate policy. Without effective mitigation, agricultural Nr emissions are expected to rise, driven by growing food demand and climate change, further exacerbating their negative impacts on air quality and the climate. This review provides a process-level overview of the current understanding of agricultural Nr emissions and their effects on atmospheric chemistry, with a focus on the underlying mechanisms, and also highlights research gaps and proposes future research directions.</p><h3>Recent Findings</h3><p>Agricultural Nr emissions are influenced by a variety of factors and released through multiple biotic and abiotic pathways, resulting in significant spatial and temporal variability. Our understanding of the underlying mechanisms driving agricultural Nr emissions remains incomplete, and current emission estimates are associated with substantial uncertainties. Agriculture contributes to ambient PM pollution primarily through ammonia (NH₃) emissions and to surface O₃ pollution via oxidized Nr species, including nitrous acid (HONO) and nitrogen oxides (NO_<i>x</i>). Although the chemistry of PM and surface O₃ is highly nonlinear, with sensitivities to their precursors varying widely, agricultural Nr is gradually becoming a key contributor, particularly in regions where fossil fuel emissions are declining, such as China, the USA, and Europe.
