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}

In this study, we address these gaps by quantifying and characterising litter across diverse settings in the United Kingdom (UK), encompassing coastal and inland regions, as well as urban and rural areas. Data were collected in collaboration with a major UK charity specialising in coastal litter removal, with 97 volunteers conducting monthly surveys along 200-m transects using a custom mobile application. Over five months, a total of 27,855 litter items were collected. Fragments (33 %), packaging (33 %), and cigarette-related debris (23 %) were the most prevalent litter types, each displaying varying trends in abundance across different locations. Litter density was higher in coastal areas (0.053 items/m²) compared to inland regions (0.030 items/m²), and urban areas consistently exhibited more litter than rural areas (urban 0.046 items/m² vs. rural 0.038 items/m²). Over time, coastal areas experienced a significantly higher influx of new litter (p < 0.0001) compared to inland regions, where litter levels were stable or decreasing. Notably, while coastal areas showed no significant difference in litter accumulation between urban and rural communities, inland urban areas had significantly more litter than their rural counterparts (p < 0.0001).

This study investigates how different beach morphodynamics and local management practices (i.e. pollutant sources, tourism, beach cleaning) influence microplastic pollution in sandy beach sediments in Vietnam by comparing tidal zonation patterns across three beaches with varying slopes and management approaches. 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. Our findings highlight a complex interplay between beach morphodynamics and local pollution sources in driving microplastic distribution.

Fungal endophytes that live inside plant leaves and roots could potentially mitigate plant heat stress from global warming. 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. Overall, warming-driven disruption of fungal endophyte community structure and function suggests that this symbiosis may not be a reliable mechanism to promote plant resilience and ameliorate stress responses under global change.</p>\u0000 </div>","PeriodicalId":175,"journal":{"name":"Global Change Biology","volume":"31 4","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875676","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}

The results obtained from the CO₂ adsorption tests showed that the red mud-based solid amine adsorbent obtained a significantly higher CO₂ capacity in comparison to the pristine red mud. Moreover, the type of the organic amine and the loading had a significant impact on the adsorption performance.

The long-term global dynamics of these habitats, however, remain largely unknown. In this study, we compiled environmental covariates from 39 published papers that assessed habitat suitability for Asian elephants. Using these covariates and a habitat suitability index model, we investigated the interannual dynamics of habitat suitability across the species' range from 2000 to 2020. Additionally, we analyzed trends in habitat fragmentation during the same period. Our findings revealed a significant 4.36 % decline in suitable habitat areas over two decades. Interestingly, a tipping point occurred around 2014, when habitat suitability stabilized and began to show slight improvement. However, habitat fragmentation continued to worsen throughout the study period. Notably, habitat suitability was higher in transboundary regions, where degradation was less severe than within protected areas. After 2018, habitat suitability in transboundary regions surpassed that of the protected areas. These findings emphasize the need to prioritize the protection of remaining Asian elephant populations and address the challenges of habitat fragmentation and connectivity across the species' range.
