To investigate this, we conducted a series of avoidance experiments using Enchytraeus crypticus in clean versus contaminated soil with silver nanomaterials (Ag NM300K). Initially, we exposed a population of these organisms via a conventional avoidance test to the contaminant and then divided them into two groups: those that avoided the contaminated soil (A group) and those that did not (Non-A group). The A group was exposed (again via an avoidance test) to the contaminated soil three more times, each time continuing only with the organisms that avoided it. In total, they underwent four repeated exposures. The Non-A group was treated similarly, but only the non-avoiding organisms were continued in each subsequent exposure. We found that avoidance behaviour increased with repeated exposures in the A group.

We used data from the French PELAGIE mother-child cohort follow-up at 12 years old which included a questionnaire on menstruation characteristics. POP concentrations of 14 organochlorine pesticides (OCPs), 17 polychlorinated biphenyls (PCBs), 5 polybrominated diphenyl ethers (PBDEs), and 9 per-polyfluoroalkyl substances (PFAS) were measured on cord blood sampled at birth.

However, many of these compounds are classified as persistent organic pollutants due to their biaccumulative nature, additionally having toxic and neurotoxic effects to humans and animals. Significant stocks of obsolete chloroaromatics, along with numerous heavily contaminated sites worldwide—including air, surface water, groundwater, and soil—underscore the urgent need for efficient remediation strategies. Chemical reduction has emerged as a well-stablished and effective approach for the transformation and/or valorization of chloroaromatics, particularly chlorobenzenes, into less toxic and higher-value compounds, such as cyclohexane and benzene. This approach may also yield other specific products such as methane, polyaromatics, and carbon-based nanomaterials.In this review, we provide the first comprehensive and also critical assessment of all hydrodechlorination and chemical reduction methods applied to the transformation, remediation, and valorization of chlorobenzenes. All the available literature has been analyzed in terms of practical feasibility, limitations, cost-effectiveness, and scalability. Reduction strategies are categorized by the type of reducing agent, distinguishing between stoichiometric and catalytic methods. The performance of various reductants—including metals, metal sulfides, hydrogen gas, hydrides, and water—in combination with a long series of organic and inorganic hydrogen donors (<i>e.g</i>. hydrocarbons, alcohols, formates, silanes, hydrazine) is thoroughly evaluated. Finally, insights into the electrochemical and photochemical reduction of chlorobenzenes in both polluted water and soil are also provided.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"40 1","pages":"1-29"},"PeriodicalIF":12.6,"publicationDate":"2025-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Electrochemical adsorption emerges as a promising technology due to its simplicity, controllability, and eco-friendliness. Manganese oxides (Mn oxides), naturally abundant and electrochemically active, exhibit substantial adsorption capacities and selectivity for various metal ions in aqueous solutions, making them excellent candidates for this technology. This comprehensive review synthesizes the latest developments in Mn oxides-based electrochemical adsorption from fundamentals to applications. This review finds that the superior performance of Mn oxides stems from a synergy of multiple mechanisms. Beyond conventional electric double-layer adsorption, pseudocapacitive ion storage and surface redox reactions play a dominant role, offering a significant advantage in terms of both capacity and selectivity. The analysis reveals that this performance is intricately dependent on a delicate interplay between the material’s intrinsic properties (such as crystal structure, morphology, and average oxidation state), solution chemistry (including pH and the presence of co-existing ions), and operational parameters. Furthermore, this review provides a detailed overview of the diverse applications of Mn oxides electrodes, spanning not only wastewater treatment for heavy metals and radioactive ions but also crucial resource recovery endeavors such as seawater desalination, water softening, and lithium extraction. By offering a critical framework for understanding these complex mechanisms and identifying key influencing factors, this work provides a roadmap for the rational design of next-generation Mn oxides adsorbents and the future development of electrochemical metal ion recovery technologies.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"95 1","pages":""},"PeriodicalIF":12.6,"publicationDate":"2025-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
