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}

Effective environmental governance is critical for the sustainable management of volcanic lakes, particularly in regions prone to natural hazards like the Dieng Plateau. Several hazards have been reported, including phreatic explosions. 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. Key recommendations include fostering inclusive decision-making processes and promoting knowledge exchange and capacity-building initiatives with collaborative environmental governance approaches.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370322","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}

Fish collected from Kent Lake in 2017 had high concentrations of perfluorooctane sulfonate (PFOS) in fillets which resulted in a fish consumption advisory from the Michigan Department of Health and Human Services (MDHHS). 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. However, the PFOS decline in fish tissue reached a plateau at a level exceeding the \"Do Not Eat\" advisory threshold. This case study sought to explore the supposition that sediment is acting as an ongoing source of PFAS to the Kent Lake food web. We sampled PFAS in biota, sediment and water from Kent Lake and a nearby reference lake in 2021. Biota (benthos, forage fish and predator fish) were collected from both lakes and analyzed as whole-body composites for PFAS analytes. The results, including the patterns of PFAS contamination between the water, sediment and biota samples as well as partition coefficients and bioaccumulation factors, are consistent with PFAS in sediment acting as an ongoing source of contamination to the biota in Kent Lake.

While multiple methods exist (e.g., Monte Carlo simulations, Bayesian networks) along with some federal and state regulatory guidance, gaps remain in prescriptive regulatory recommendations for the implementation of PRA methods.

However, ERA is not concerned with toxicity under laboratory conditions: it needs to assess the impacts of the compound in the real world. Data-driven statistical analyses (e.g., hypothesis testing and interpolation) are the common approaches for analysing toxicity data, but such approaches are the wrong tool for the job at hand. ERA does not need a statistical description of the effects in the toxicity test (at the end of the standardised test duration), it needs to extrapolate from the laboratory test to longer and time-varying exposure. Such extrapolation requires mechanistic process models, providing a simplified representation of the mechanisms underlying toxicity. Any useful model for the toxicity process should explicitly consider both dose (e.g., exposure concentration) and time. In the history of effects analysis for ERA, the factor of time does not get as much attention as the dose, hence common use of the term 'dose-response analysis'. However, this is a historical oversight: time is a crucial factor for understanding toxicity and thereby essential for meaningful extrapolation from laboratory to field. Mechanistic models for ecotoxicity, considering both dose and time, have been around for quite some time and are classified as toxicokinetic-toxicodynamic (TKTD) models. TKTD models are starting to find their way into pesticide ERA in Europe, next to the classical statistical approaches. In this opinion paper, I argue that it is about time to leave statistical analysis of toxicity data behind us. Statistics remains important for ERA's effects assessment, but its role lies in the definition of appropriate 'error models', explaining the deviations between model output and observations, which is essential for parameter estimation, uncertainty quantification, and error propagation.

The parameters analyzed were: temperature, pH, turbidity, settleable solids, DO, BOD, NO3-, NO2-, NH4+, PO4-3, total and thermotolerant coliforms, Fe, Ni, Cr and Zn. PO4-3, pH, BOD and thermotolerant coliforms sometimes exceed the freshwater limits set by the National Environment Council (CONAMA 357/05, 2005).

Temporal analysis using non-parametric tests showed significant differences (p < 0.05) in almost all parameters, indicating a strong influence of precipitation patterns on water quality.
