Breakthrough of the microfluidics involved in heavy metals control has accelerated in recent years along with realization of the ubiquity, non-degradability, bioaccumulation, mobility and reactivity of heavy metals in the environment. This review explores recent advances in microfluidic applications for heavy metal control, spanning detection, separation, and recovery. Among microreactors, droplet-based systems demonstrate exceptional performance in detecting trace contaminants, achieving detection limits below 0.5 µg/L through enhanced mixing and reaction efficiency. For separation, liquid-liquid extraction microreactors stand out, with optimized interfaces yielding extraction efficiencies of up to 99.3% for cadmium (Cd) under specific flow and pH conditions. In the realm of recovery, electrochemical microreactors have shown potential for selective deposition, achieving high recovery rates at optimized current densities and tailored electrode materials. Future work will focus on the design and development of functional integration and scale-up of microfluidic systems/platforms, particularly in terms of the flexibility of microfluidic device design and assembly, as well as the efficiency of mass and heat transfer and reactions. The precise process control characteristics of microfluidic systems make them highly promising for applications in environmental monitoring, pollution control, and resource recovery.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"6 1","pages":"1-21"},"PeriodicalIF":12.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136781","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}

To date, more than 100 microbial species have been reported to enter the VBNC state under various stressful conditions. In the VBNC state, cells undergo morphological, physiological, and genetic changes, with the mechanisms of VBNC state formation differing among microbial species and stressful conditions. Although the VBNC state has been extensively investigated in the fields of medicine and food safety, research on the VBNC state of pollutant-degrading microorganisms remains limited. Mounting evidence has confirmed the existence of the VBNC state in microorganisms capable of degrading polychlorinated biphenyls (PCBs) and phenol. The resuscitation of VBNC microorganisms, which represent a significant portion of microbial resources, is crucial for the effective microbial remediation of polluted environments. This review provides a comprehensive summary of the formation, characteristics, and mechanisms of the VBNC state in microorganisms. It also outlines various methods for resuscitating VBNC bacteria, with a specific focus on resuscitation-promoting factors (Rpfs). Importantly, from the perspective of environmental bioremediation, this review highlights the potential of VBNC state bacteria, the application of Rpfs in resuscitating VBNC bacteria in polluted environments, and the feasibility of utilizing resuscitated strains as inoculants for environmental bioremediation.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"95 1","pages":"1-24"},"PeriodicalIF":12.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910012","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}

In comparison with the biochars derived from wood chips and grass, the biochar produced from nutrient-enriched feedstocks (e.g., sewage sludge, animal manure, microalgae, and wetland plants) contained higher contents of nutrients and showed greater potential for soil application. To achieve the efficient utilization of nutrients in biochar, the behavior of nitrogen (N), phosphorus (P), and potassium (K) during pyrolysis of nutrient-enriched feedstock should be clarified. This study provides a systematic review of the migration and transformation of N, P, and K during the production of biochar derived from nutrient-enriched biomass, with special emphasis on the effects of nutrient-enriched biochar on soil available nutrients. Perspectives and challenges for agricultural applications of biochar are discussed as well. The migration and transformation of N, P, and K are affected by the pyrolysis temperature and the properties of the feedstock during the pyrolysis process. The application of nutrient-enriched biochar could provide additional nutrients, change the physicochemical properties of soil, and modify microbial community to elevate the content of soil available nutrients.

The analysis reveals that enhancing the utilization of reactive species can be achieved through two main approaches: (i) enhancing the mass transfer of reactive species, and (ii) improving the generation of reactive species with strong redox potential (such as <sup>•</sup>OH and e<sub>aq</sub><sup>–</sup>). The maximum utilization of reactive species can reduce the energy consumption of nonthermal plasma technology and promote its industrial application.

Methods of air purification typically rely on traditional mechanical filtration methods such as heating, ventilation and air conditioning systems, which are energetically intensive and require routine maintenance to ensure adequate filtration. To reduce energy demands and to improve urban sustainability, phytoremediation technologies have emerged as a promising method for the remediation of indoor air quality. Due to the need to identify and optimize sustainable methods to improve air quality, we present a comprehensive review on the mechanisms for plant-driven and microbial-driven removal of gaseous contaminants (i.e. volatile organic compounds) is warranted. The literature indicates that indoor air phytoremediation systems rely on complex of both the biological aspects (plant parts, substrate, microbial community, substrate moisture) and abiotic factors (airflow and moisture content), however it is evident that the method for optimal application of these factors within systems is currently significantly understudied, especially in relation to research done <i>in-situ</i>. The authors recommend future research directions should be targeted at plant biochemical analysis of phytoremediation systems exposed to real world pollutants like petroleum vapor, vehicle emissions, and mixed synthetic furnishings of-gassing, as well as the dynamics of the substrate microbial community within root systems.

However, most commercially available biodegradable plastic products are blended/composite materials, combining biodegradable polymers with other polymers, fillers and additives. Non-reactive functional additives, such as plasticizers and stabilizers, raise concerns due to potential leaching as well as release on degradation. Thus, understanding how these additives affect biodegradation rates and processes is crucial, and a comprehensive overview is missing in the literature. This review highlights that the localized additive concentration levels adjacent to the plastic materials could, at least for a time, exceed the threshold concentrations for substantial impacts on microbial activities, especially in slow transport media such as soil and compost. Of the available literature, it is concerning that only a small fraction reported continuous quantitative biodegradation data with sampling frequency and duration adequate for comprehensive data synthesis. In those studies, the presence of additives resulted in an extended lag time for biodegradation compared to virgin polymer. Interestingly, additives also typically increased the biodegradation rate following this initial lag time. Overall, variation was observed in the half-life of biodegradable polymer/additive blends when considering both lag time and biodegradation rate. The likely key controlling factors dictating how additives impact biodegradable plastics biodegradation include the rate of additive leaching, alterations in polymer properties induced by additives and their leaching, and the intrinsic characteristics of the additives themselves. Future life cycle analysis and environmental impact assessments of new bioplastic products must consider the influence of additives.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"183 1","pages":"708-731"},"PeriodicalIF":12.6,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827261","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}
