As a result, ecosystems can be protected, using frameworks and procedures incorporated into regulatory approaches. Yet, when evaluating how freshwater risks from metals are assessed globally, it is apparent that regulatory jurisdictions differ in their progress, and approaches, when accounting for bioavailability. It is entirely reasonable and appropriate for there to be a lag in time between the development of the science and its incorporation into routine regulatory environmental protection. We openly acknowledge that this is not just a regulatory challenge and take a more holistic view of the implementation of the science that informs metal bioavailability. Implementation comprises the steps required to utilize science and knowledge to enable its practical, beneficial, and routine application in regulatory decision making. Different regulatory jurisdictions have taken varied approaches to account for metal bioavailability. We have made specific use of frameworks that utilize limit values, such as water quality guidelines, criteria and quality standards, to illustrate the similarities and differences in the implementation of bioavailability. Approaches taken in Europe, Canada, Australia and New Zealand, and the United States were reviewed and evaluated. While some of these approaches, or parts thereof, have been successful, other aspects have been less so. In this evaluation, we have identified key commonly encountered obstacles and challenges in these approaches to the implementation of metal bioavailability. Finally, we provide an evidence-driven 'road map' to the successful regulatory implementation of metal bioavailability in risk assessment, drawn from successful components of the approaches reviewed. The application of this framework will enable regulatory jurisdictions to readily keep pace with the science pertaining to metal bioavailability and avoid the challenges experienced by others.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143491910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Constructing ecological networks is vital in improving landscape connectivity, protecting biodiversity, and maintaining regional sustainable development. Ningbo, China was set as the research area. The geographic information system (GIS) and the morphological spatial pattern analysis (MSPA) were employed to determine the ecological source area. Subsequently, the corridor design model Linkage Mapper was employed to ascertain and assess the linkages between the designated ecological source areas. The results showed that: (1) From 2000 to 2020, there was a large-scale change in land use type in Ningbo, with increasing complexity of patches and landscape fragmentation. The ecological sources of the three periods in Ningbo were primarily situated in the western, southern, and Hangzhou Bay coastal regions, exhibiting an uneven distribution in the eastern and western areas. (2) The number of primary ecological corridors in Ningbo underwent a significant reduction, from 26 to 17, between the years 2000 and 2020. In terms of the distribution of ecological corridors, the primary corridors were concentrated in the central, southern, and western regions of the study area in 2000. By 2020, however, the primary ecological corridors within the study region were distributed mainly in a southerly direction. The interaction between North and South ecological sources was weakened, which adversely affected the species spread and ecosystem stability.

The effectiveness of this approach was assessed via a field-scale trial conducted at an airport in Australia. Prior to full-scale treatment, laboratory trials were undertaken to determine optimal treatment reagents and application rates. The Standardised Sorbent Qualities Measure (SSQM) and Matrix Sorbent Qualities Measure (MSQM) were developed and applied to assess sorbent sorption/desorption capacity for PFAS under standardised conditions, facilitating sorbent selection. Three blending techniques were employed for field-scale trials: manual mixing with an excavator, large-scale rapid mixing using a pug mill, and a portable trommel screen. The efficacy of soil blending with a RemBind sorbent was validated using the sum of and leachable perfluorooctanesulfonic acid (PFOS) + perfluorohexanesulfonic acid (PFHxS) assessments. Results showed a substantial reduction in PFAS leachability, with mean PFOS + PFHxS concentrations generally decreasing to below the limit of reporting, resulting in over 98% reductions in leachable fractions. The Sorbent Application Uniformity Test (SAUT) effectively served as a quality assurance and quality control (QA/QC) measure alongside PFAS analysis, demonstrating consistent sorbent-soil blending across all methods evaluated. Overall, the large-scale trial at the airport confirmed that immobilisation using 1% to 2% RemBind 100 sorbent offered a viable, sustainable, and cost-effective solution, particularly for PFOS and PFHxS. Applying novel SSQM/MSQM and SAUT methods combined with pre-and post-treatment leachability analysis established a clear link between the sorbent application specification determined from laboratory-scale trials and field validation requirements. Thus, these methods are pertinent for assessing the immobilisation technique's efficacy and sorbent blending quality.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143440727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Simultaneously, the poor management and underutilization of agricultural biomass waste presents an additional environmental challenge. Converting this biomass into biochar offers a potential solution to these challenges. This study evaluated biochar's impacts on soil trace element content, rice plant uptake, translocation, accumulation, and associated human health risks while identifying rice response mechanisms to biochar application. A two-season field experiment was conducted using five treatments: T1 (no biochar), T2 and T3 (10 and 20 tons of rice-husk biochar), and T4 and T5 (10 and 20 tons of longan biochar). Eight trace elements, categorized as micronutrients (Fe, Mn, Cu, Zn) and toxic elements (Cd, Pb, Co, Ni), were measured in rice roots, stems, grains, and soil. Biochar application reduced the heavy metal pollution index (HPI) by 5.9% to 11.4% for micronutrients and 2.8% to 4.4% for toxic elements compared to T1. Translocation, bioaccumulation, and phytoextraction indexes tend to increase with biochar, while the hazard index decreased by 5.1-9.5% for micronutrients and 1.3-8.5% for toxic elements, indicating reduced health risks. These results highlight biochar's dual role in enhancing trace element phytoextraction and reducing health risks, with a more pronounced effect on micronutrients. Rice plants responded to reduced micronutrient availability by boosting uptake while lowering toxic element absorption when HPI was high. Briefly, transforming agricultural waste into biochar for rice cultivation offers multiple benefits, promoting agricultural sustainability, environmental health, and consumer safety.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This paper explores a multidisciplinary approach to environmental governance, integrating ecological sciences and social sciences, to ensure the sustainable management of these lakes. We investigated the necessity and challenges of establishing collaborative environmental governance mechanisms to address the complex issues surrounding Lake Menjer as volcanic lake management in the region. Based on an investigation of water quality and biodiversity, all nutrient inputs from anthropogenic activities promoted this lake's degradation. The environmental degradation of the lake showed the absence of management institutions. Drawing upon multidisciplinary research and stakeholder engagement, this study aims to: 1) to analyze the trend of environmental degradation in Lake Menjer in terms of eutrophication; and 2) to evaluate the current governance structures and propose strategies for enhancing collaboration among the various stakeholders. We analyzed existing policies, institutional frameworks, and community participation models to identify gaps and opportunities for improving environmental governance practices. We also advocate for a holistic and sustainable approach to volcanic lake management that balances ecological conservation and socio-economic development in Lake Menjer by fostering collaboration and co-management approaches.

In June 2018, a major source of PFOS was identified as the City of Wixom's wastewater treatment plant (WWTP) which discharges treated effluent to Norton Creek and the Huron River 5 miles upstream of Kent Lake. An industrial facility, which has been in operation since approximately 2000, was found to be the source of high levels of PFOS to Wixom's sanitary sewer. A granular activated carbon (GAC) system was installed at the facility, resulting in substantial reductions in PFOS concentrations in surface water and fish from Kent Lake.
