Background:

Despite well-documented inequities in exposure to environmental toxicants, limited evidence exists on how neighborhood vulnerabilities intersect with the US Housing and Urban Development (HUD)-subsidized housing and whether such housing modifies these disparities. This study examines whether the presence and type of HUD-assisted housing modifies the association between neighborhood social vulnerability and exposure to industrial air toxicants.

Methods:

Using the 2022 Environmental Protection Agency Risk-Screening Environmental Indicators air toxicant scores at the census tract level, this nationwide ecological cross-sectional study assessed their association with neighborhood social vulnerability as measured by the Centers for Disease Control and Prevention Social Vulnerability Index. We additionally evaluated how these associations differed by the presence and type of HUD-assisted housing (public housing, housing voucher holders, and project-based multifamily housing) using tract-level regression models.

Results:

Greater neighborhood social vulnerability was associated with higher environmental toxicant scores. The presence and type of HUD-assisted housing significantly modified these associations, indicating that the nature of the association between neighborhood social vulnerability and toxic air exposure depends on the presence versus absence of certain HUD housing types.

Conclusion:

The observed relationships between toxic air concentrations, social vulnerability, and HUD-assisted housing highlight the need for preventive, equity-focused housing and environmental policies to reduce exposure risks.

背景：尽管有充分的证据表明暴露于环境毒物方面存在不平等，但关于社区脆弱性与美国住房和城市发展（HUD）补贴住房之间的关系以及此类住房是否改变了这些差异的证据有限。本研究考察了hud辅助住房的存在和类型是否改变了社区社会脆弱性与暴露于工业空气毒物之间的关系。方法：使用2022年环境保护局风险筛选环境指标在人口普查区水平的空气毒物得分，这项全国性的生态横断面研究评估了它们与社区社会脆弱性的关系，并由疾病控制和预防中心的社会脆弱性指数测量。此外，我们使用区域水平回归模型评估了hud援助住房（公共住房、住房券持有人和基于项目的多户住房）的存在和类型如何影响这些关联。结果：较高的社区社会脆弱性与较高的环境毒物评分相关。HUD辅助住房的存在和类型显著地改变了这些关联，表明社区社会脆弱性与有毒空气暴露之间的联系的本质取决于某些HUD住房类型的存在与否。结论：观察到的有毒空气浓度、社会脆弱性和hud援助住房之间的关系突出了预防性、以公平为重点的住房和环境政策的必要性，以降低暴露风险。

The term “resprouting” is commonly used to classify species into functional groups, despite variable resprouting responses of many species. Variance in post-fire resprouting and inconsistencies when reporting on this may lead to misapplication when managing species for conservation. We aimed to compile all available literature to explore and quantify inconsistencies within the classification of species as post-fire resprouters when reported. Further, we investigated how much any one species might vary in resprouting following fire, and if changes in fire severity contributed to this.

We undertook a comprehensive literature review using PRISMA methodology, focused on papers that quantified percentage resprouting following fire with changing fire severity. We compared reporting of resprouting against standardised definitions and used generalised linear models and pairwise comparisons to quantify how resprouting varies within and between species, and with fire severities.

We found 507 papers from 54 countries that observed or quantified post-fire resprouting, with 144 of these quantifying percentage resprouting across 737 species. The term “resprouter” was rarely applied using standardised thresholds. Resprouting varied within and between species, with vegetation type, and fire severity. Extreme fire severity consistently reduced resprouting compared to high severity.

Resprouting is a complex continuous response within species. Minimal reporting of metrics likely driving resprouting variation impedes comparison of resprouting across disturbance regimes and hinders our ability to determine susceptible species with changing fire regimes.

We proposed clarifying terminology to show nuance, highlighting when there is a lack of information within resprouting responses, ensuring land managers can confidently achieve species-specific outcomes in an informed way.

术语“再生”通常用于将物种划分为功能组，尽管许多物种的再生反应是可变的。火灾后再生的差异和报告的不一致可能导致在管理保护物种时误用。我们的目标是汇编所有可用的文献，以探索和量化在报道时物种分类中作为火灾后呼吸器的不一致性。此外，我们调查了任何一种物种在火灾后的再生可能会有多大变化，以及火灾严重程度的变化是否会导致这种变化。我们使用PRISMA方法进行了全面的文献综述，重点是量化火灾严重程度变化后火灾逃生百分比的论文。我们比较了标准化定义下的再生报告，并使用广义线性模型和两两比较来量化再生在物种内部和物种之间以及火灾严重程度上的变化。我们发现来自54个国家的507篇论文观察或量化了火灾后的再生，其中144篇论文量化了737种物种的再生百分比。术语“resprouter”很少使用标准化阈值。再生在物种内部和物种之间，随植被类型和火灾严重程度而变化。与高度严重的火灾相比，极端严重的火灾会持续减少再生。繁殖是物种内部复杂的连续反应。很少报告可能导致再生变化的指标，阻碍了跨干扰制度的再生比较，并阻碍了我们确定变化的火灾制度中易感物种的能力。我们建议澄清术语以显示细微差别，强调在再生响应中缺乏信息的情况下，确保土地管理者能够以知情的方式自信地实现特定物种的结果。

Irrigation is essential to intensive agriculture worldwide, particularly in semi-arid climates where rainfall is unreliable. The use of surface and groundwater for crop irrigation can alter aquifer dynamics by lowering water tables and degrading water quality through the leaching of agrochemicals, nutrients, and organic carbon. These changes pose significant risks to the integrity of groundwater ecosystems. To assess these impacts, we conducted a spatial and temporal study of groundwater chemistry and biota (using environmental DNA (eDNA)) in a shallow alluvial aquifer adjacent to an irrigated cotton farm in northern NSW, Australia. We sampled a series of wells in a transect stretching from an irrigated cotton farm toward the Namoi River, over an annual crop cycle. Groundwater levels declined over the year. Groundwater quality, particularly electrical conductivity and ammonia concentrations, varied with distance from the field. Water chemistry varied more between wells than over time, with wells close to the field showing distinctly different chemical characteristics to those further away. Drainage from the irrigated field was evident in the chemistry and isotopic signature of the groundwater, and also in biota. Taxa typical of surface waters and soils, and cotton DNA were more prominent in wells under the effect of irrigation. Biota displayed a potential ‘ecological memory’, where communities showed legacy effects related to past agricultural activities and hydraulic conditions. These results indicate the spatial extent of impacts of irrigation on shallow aquifers and confirm the direct and indirect effects of agricultural practices on groundwater levels, quality, and biotic communities within a short distance from an irrigated field. These findings have widespread relevance for the management of off-site impacts of irrigation activities.

灌溉对全球集约化农业至关重要，特别是在降雨不可靠的半干旱气候地区。利用地表水和地下水进行作物灌溉可以通过降低地下水位和通过农用化学品、营养物质和有机碳的浸出而降低水质来改变含水层的动态。这些变化对地下水生态系统的完整性构成重大威胁。为了评估这些影响，我们在澳大利亚新南威尔士州北部一个灌溉棉花农场附近的浅层冲积含水层进行了地下水化学和生物群的时空研究（使用环境DNA (eDNA)）。我们在从一个灌溉棉花农场到纳莫伊河的一个样带中对一系列井进行了采样，采样时间为一年一次的作物周期。地下水水位逐年下降。地下水的质量，特别是电导率和氨浓度，随着离田地的距离而变化。井与井之间的水化学变化比随时间的变化更大，靠近油田的井与远离油田的井表现出明显不同的化学特征。灌溉农田的排水在地下水的化学和同位素特征以及生物群中都很明显。在灌溉作用下，井区以地表水和土壤的典型分类群和棉花DNA更为突出。生物群显示出潜在的“生态记忆”，其中社区显示出与过去农业活动和水力条件有关的遗留影响。这些结果表明了灌溉对浅层含水层影响的空间范围，并证实了农业实践对灌溉田短距离内地下水水位、质量和生物群落的直接和间接影响。这些发现对管理灌溉活动的场外影响具有广泛的相关性。

Residual crude oil remaining in depleted reservoirs represents a largely untapped carbon source for biological hydrogen generation. Previous studies have relied on indigenous bacteria present in oil reservoirs but reported low hydrogen yields, as not all reservoir microorganisms are hydrogen-producing. Therefore, in this study, external mixed culture bacterial consortia obtained from palm oil mill effluent (POME) were used to degrade crude oil for hydrogen production. Morphological changes in microbial communities were assessed using field emission scanning electron microscopy. Metagenomic profiling was conducted to identify the dominant microbial taxa capable of producing biohydrogen. Thereafter, a high-temperature and high-pressure (800 °C/30 MPa) stainless-steel bioreactor containing crude oil was inoculated with mixed culture consortia to simulate an oilfield reservoir for hydrogen production. Box–Behnken design was applied to systematically examine the effects of exposure time (6–90 h), crude oil volume (10–40 mL), and temperature (35–70 °C) on continuous hydrogen production. Statistical analysis of variance was used to evaluate model parameters. Heat pretreatment selectively enriched hydrogenogenic spore-formers (Clostridium and Bacillus), resulting in a ~ 4-fold increase (97.40 ± 0.02 mL/L) in hydrogen yield compared to 25.68 ± 0.04 mL/L POME for untreated sludge. In the presence of crude oil, the optimum hydrogen production was 152.50 ± 0.01 mL/L at 50 °C, compared to 125.45 ± 0.03 mL/L and 29.95 ± 0.01 mL/L crude oil at 35 °C and 70 °C, respectively. Predicted hydrogen production, with R² value of 97.4% close to unity, indicates that the model was highly consistent with the experimental results, with high precision and reliability. Thermodynamic analysis shows negative Gibbs free energy changes of −122 to −236 kJ/mol, demonstrating that hydrocarbon-to‑hydrogen conversion was energetically favorable and feasible across all tested temperatures. Overall, the experimental, statistical, and thermodynamic analyses establish the technical and energetic feasibility of microbial enhanced hydrogen recovery in depleted oil reservoirs.

枯竭储层中残留的原油是生物制氢的主要未开发碳源。之前的研究依赖于油藏中存在的原生细菌，但由于并非所有油藏微生物都产氢，因此产氢率很低。因此，在本研究中，从棕榈油厂废水（POME）中获得的外部混合培养细菌联合体用于降解原油制氢。利用场发射扫描电镜观察微生物群落形态变化。进行了宏基因组分析，以确定能够产生生物氢的优势微生物类群。随后，在含原油的高温高压（800°C/30 MPa）不锈钢生物反应器中接种混合培养菌，模拟油田储层产氢。采用Box-Behnken设计，系统考察了暴露时间（6-90 h）、原油体积（10-40 mL）和温度（35-70℃）对连续制氢的影响。采用方差统计分析对模型参数进行评价。热预处理选择性地富集产氢孢子形成菌（梭状芽孢杆菌和芽孢杆菌），使产氢率（97.40±0.02 mL/L）比未经处理的POME提高4倍（25.68±0.04 mL/L）。原油存在时，50℃条件下的最佳产氢量为152.50±0.01 mL/L，而35℃和70℃条件下的最佳产氢量分别为125.45±0.03 mL/L和29.95±0.01 mL/L。预测产氢量R2值为97.4%，接近于1，表明该模型与实验结果高度吻合，具有较高的精度和可靠性。热力学分析表明- 122到- 236 kJ/mol的负吉布斯自由能变化，表明在所有测试温度下烃类转化为氢在能量上是有利的和可行的。总的来说，实验、统计和热力学分析确定了微生物提高衰竭油藏氢采收率的技术和能量可行性。

This review examines the potential of NMR- and MS-based metabolomics for environmental monitoring using bivalves as bioindicators. Bivalves, particularly mussels, play a vital role in ecological studies by providing critical insights into the impacts of water contamination on aquatic ecosystems. As water pollution continues to pose a growing global challenge, bivalves' environmental and economic importance underscores their value in monitoring programs. Metabolomics, a high-throughput analytical approach, has emerged as a powerful tool for assessing metabolic changes in organisms exposed to environmental stressors. This review explores metabolomics applications across various bivalve species, focusing on identifying biomarkers associated with contaminants and their effects on different organisms. Key aspects of study design are discussed, including extraction techniques, analytical platforms, and the development of tailored protocols to address metabolite class specificity, method efficiency, safety, and reproducibility. Furthermore, we highlight how bivalve metabolomics contributes to biomarker discovery and the elucidation of toxicity mechanisms. By addressing both the benefits, such as its sensitivity and broad applicability, and the challenges, such as sample preparation and data complexity, our review provides a unified perspective on the ecological and human health implications of using bivalve metabolic profiles for environmental biomonitoring.

本文综述了利用双壳类作为生物指标的核磁共振和质谱代谢组学在环境监测中的潜力。双壳类，特别是贻贝，在生态学研究中发挥着至关重要的作用，为水污染对水生生态系统的影响提供了重要的见解。随着水污染对全球构成越来越大的挑战，双壳类在环境和经济方面的重要性凸显了它们在监测项目中的价值。代谢组学是一种高通量分析方法，已成为评估暴露于环境应激源的生物体代谢变化的有力工具。本文综述了代谢组学在各种双壳类动物中的应用，重点是识别与污染物相关的生物标志物及其对不同生物的影响。讨论了研究设计的关键方面，包括提取技术，分析平台，以及针对代谢物类别特异性，方法效率，安全性和可重复性的定制方案的开发。此外，我们强调双壳类代谢组学如何有助于生物标志物的发现和毒性机制的阐明。通过解决其优点（如灵敏度和广泛适用性）和挑战（如样品制备和数据复杂性），我们的综述为使用双壳类代谢谱进行环境生物监测的生态和人类健康影响提供了统一的视角。

Key aspects of study design are discussed, including extraction techniques, analytical platforms, and the development of tailored protocols to address metabolite class specificity, method efficiency, safety, and reproducibility. Furthermore, we highlight how bivalve metabolomics contributes to biomarker discovery and the elucidation of toxicity mechanisms. By addressing both the benefits, such as its sensitivity and broad applicability, and the challenges, such as sample preparation and data complexity, our review provides a unified perspective on the ecological and human health implications of using bivalve metabolic profiles for environmental biomonitoring.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1016 ","pages":"Article 181461"},"PeriodicalIF":8.0,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076037","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}

Brazil's semi-arid region faces acute water scarcity challenges affecting 28 million inhabitants, with rural communities particularly vulnerable due to inadequate sanitation infrastructure (75% lack proper sewage treatment) and limited access to reliable water sources. The main scientific challenge lies in developing integrated waste-to-energy solutions that can operate effectively under water-constrained conditions while addressing both energy security and environmental sustainability. The objective of this study was to evaluate the feasibility of substituting conventional water with domestic greywater (GW) in anaerobic co-digestion of cattle manure (CM) under semi-arid conditions. Bench-scale bioreactors (350 mL working volume) were operated under mesophilic conditions (36 ± 2 °C) with systematic evaluation of varying GW dilution ratios (25%, 50%, 75%, and 100% v/v) over 76 days. Biogas production kinetics were analyzed using the modified Gompertz equation, and comprehensive physicochemical characterization was performed using standard analytical methods. Physicochemical characterization revealed CM had high nutrient density and organic matter content, while GW exhibited low total solids and chemical oxygen demand, positioning it as a viable co-substrate. Maximum biogas production increased from 951.9 ± 55.7 mL g VS⁻¹ (control) to 1235.0 ± 43.8 mL g VS⁻¹ (100% GW). Wobbe Index values improved from 31.10 ± 1.65 MJ m⁻³ (control) to 53.29 ± 2.76 MJ m⁻³ (25% GW), confirming enhanced biogas quality. Multielemental analysis by inductively coupled plasma optical emission spectrometry identified low concentrations of inhibitory trace metals in GW. Digestate phytotoxicity assessment using Lactuca sativa germination assays demonstrated germination indices above 100% at 10% dilution for most treatments, indicating biostimulant potential. The results demonstrate that GW-assisted anaerobic digestion significantly enhances biogas yield (up to 30% increase) while producing nutrient-rich digestates suitable for agricultural application, offering a sustainable solution for integrated waste and water management in water-scarce rural regions.

巴西半干旱地区面临严重缺水挑战，影响2800万居民，农村社区由于卫生基础设施不足（75%缺乏适当的污水处理）和获得可靠水源的机会有限而特别脆弱。主要的科学挑战在于开发能够在水资源紧张的条件下有效运行的综合废物转化能源解决方案，同时解决能源安全和环境可持续性问题。本研究旨在探讨在半干旱条件下用生活中水（GW）代替常规水厌氧共消化牛粪（CM）的可行性。在中温条件下（36±2°C），实验规模生物反应器（350 mL工作体积）运行76天，系统评估不同GW稀释比（25%,50%，75%和100% v/v）。采用改进的Gompertz方程分析了产气动力学，并采用标准分析方法进行了综合理化表征。理化性质表明，CM具有较高的营养密度和有机质含量，而GW具有较低的总固体和化学需氧量，是一种可行的共底物。最大沼气产量从951.9±55.7 mL g VS - 1（对照）增加到1235.0±43.8 mL g VS - 1 （100% GW）。Wobbe指数从31.10±1.65 MJ m−3（对照）提高到53.29±2.76 MJ m−3 (25% GW)，证实了沼气质量的提高。用电感耦合等离子体发射光谱法进行多元素分析，鉴定出GW中低浓度的抑制性微量金属。利用芥蓝（lacuca sativa）发芽试验进行的消化植物毒性评估显示，在大多数稀释度为10%的处理下，发芽指数都在100%以上，表明具有生物刺激素的潜力。结果表明，gw辅助厌氧消化显著提高了沼气产量（最高可提高30%），同时产生适合农业应用的营养丰富的消化液，为缺水农村地区的废物和水综合管理提供了可持续的解决方案。
