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. The assessment and developed understanding of these key areas are not only essential for the progression of the field of research but also for continued wide spread adoption for these phytoremediation systems.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"108 1","pages":"676-707"},"PeriodicalIF":12.6,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827218","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}

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}

Managing membrane concentrates poses significant challenges, often resulting in underutilization of their valuable components. This paper discusses strategies for reducing, rendering harmless, and utilizing resources from membrane concentrates, along with their future development trends. Methods for reducing membrane concentrate formation, such as optimizing operational modes and membrane modification, are examined. Generally, the preprocessing methods can be used as an oxidation pretreatment to improve the removal of macromolecular pollutants in the membrane concentrates, and provide conditions for the targeted removal of non-biodegradability emerging contaminants by free radicals in the oxidation process. The biological treatment further treats biodegradable pollutants. Finally, biosafety and water quality can be guaranteed through the membrane process, so as to achieve near-zero emissions. Resource recovery options include the production of salt crystals (e.g., potassium and magnesium phosphate, hydroxyapatite), microalgae resources, and others. Additionally, non-chemical pretreatment before membrane processing is proposed to simplify the treatment of membrane concentrates. A new analytic hierarchy process aids in selecting appropriate treatment and resource utilization processes for membrane concentrates. Furthermore, there is a call for the establishment and reinforcement of water quality legislation to address emerging contaminants in membrane concentrates, as well as regulations governing the purity of resources such as salts recovered from membrane concentrates.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"24 1","pages":"1-27"},"PeriodicalIF":12.6,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827264","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}

While low to medium doses of HM exposure may not directly result in crop reduction, they can lead to HM accumulation in plants and potential food-chain risks, as well as trigger the accumulation of reactive oxygen species (ROS). Excessive ROS can cause oxidative stress and irreversible damage to plant cells. Nanozymes, cost-effective and stable artificial nanoparticles with enzyme-like activity, have been widely used in multiple fields. Over the past decade, research has confirmed certain nanozymes’ effectiveness in plant systemic immunity during HM remediation. The activities of nanozymes hinge on their physicochemical properties, while the biological effects also depend on application methods, size, charge, coating, crop varieties, and growth stages. Therefore, it is crucial to understand the nanozyme-plant interactions and resistance mechanisms to HMs. This paper comprehensively reviews nanozyme-mediated ROS scavenging mechanisms across enzymology, metabolomics, proteomics, and transcriptomics. It also introduces the application pathways and effects, influencing factors, possible risks, and prospects. This review may provide a theoretical framework for nanozyme-mediated mitigation of HM stress along with other abiotic stresses in agriculture for sustainable “precision fertilization” with nanozymes.","PeriodicalId":10823,"journal":{"name":"Critical Reviews in Environmental Science and Technology","volume":"39 1","pages":"732-756"},"PeriodicalIF":12.6,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827322","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}

Environmental variables (Chlorophyll a, total organic material, grain size) and microplastics polymer composition, size and concentrations were measured at the high and the low water marks of each beach. Microplastics were found on all beaches, with high variation. The dominance of denser MPs, like PET, on reflective beaches coupled with the prevalence of lighter MPs in the high tidal zone, demonstrates the role of beach morphodynamics and tidal flows in shaping microplastic distributions. Furthermore, local waste management practice and input from tourism activities can contribute to the patchy microplastics distribution. For instance, the larger size of microplastics at the beach with most macrolitter suggests the role of fragmentation down to microplastics as a pollution source which can pose risks to benthic ecology and human health in regional communities.

Conversely, disruptions of these symbioses could exacerbate the negative impacts of warming. To better understand the consistency and strength of warming-induced changes to fungal endophytes, we examined fungal leaf and root endophytes in three grassland warming experiments in the US ranging from 2 to 25 years and spanning 2000 km, 12°C of mean annual temperature, and 600 mm of precipitation. We found that experimental warming disrupted symbiosis between plants and fungal endophytes. Colonization of plant tissues by septate fungi decreased in response to warming by 90% in plant leaves and 35% in roots. Warming also reduced fungal diversity and changed community composition in plant leaves, but not roots. The strength, but not direction, of warming effects on fungal endophytes varied by up to 75% among warming experiments. Finally, warming decoupled fungal endophytes from host metabolism by decreasing the correlation between endophyte community and host metabolome dissimilarity. These effects were strongest in the shorter-term experiment, suggesting endophyte-host metabolome function may acclimate to warming over decades.
