The environmental persistence and ecotoxicity of polycyclic aromatic hydrocarbons (PAHs) have stimulated considerable interest in understanding their bioaccessibility and biodegradation in soils. Factors such as contact time, organic amendments, and microbial inoculation can influence these processes. This study examined how contact time, bacterial inoculation, and amendments affect the chemical extractability and biodegradation of 9-¹⁴C-phenanthrene in soil. Soils were amended with anaerobic digestate (AD), wood ash (WA), or their combination (AD + WA) and monitored over 90 days. Lower recoveries of 9-¹⁴C-phenanthrene activity were observed in amended soils compared with the control, particularly in AD + WA treatments, with recoveries declining over time. Both dichloromethane (DCM) and hydroxypropyl-β-cyclodextrin (HP-β-CD) extractability decreased with increasing soil – PAH contact time, with a greater reduction in HP-β-CD extractability observed in AD + WA. Inoculated systems exhibited shorter lag phases than uninoculated systems, although bacterial numbers, mineralisation rates, and extents were similar across both inoculation conditions. Lower mineralisation extents occurred in AD + WA under both inoculation conditions. This study provides new insights into how AD, WA, and AD + WA influence PAH bioaccessibility and mineralisation kinetics in soil. The findings indicate that AD and/or WA can stimulate 9-¹⁴C-phenanthrene biodegradation under nutrient-limited conditions, primarily through biostimulation of indigenous microbial communities; however, bioaccessibility rather than nutrient availability or microbial abundance, ultimately constrained degradation endpoints. These results highlight the need for (bio)remediation strategies that enhance contaminant availability, rather than focusing solely on nutrient inputs or microbial abundance.

多环芳烃（PAHs）的环境持久性和生态毒性引起了人们对其在土壤中的生物可及性和生物降解的极大兴趣。诸如接触时间、有机改性剂和微生物接种等因素可以影响这些过程。本研究考察了接触时间、细菌接种和修正对土壤中9- 14c -菲的化学萃取性和生物降解性的影响。用厌氧消化液（AD）、木灰（WA）或它们的组合（AD + WA）对土壤进行了90天的监测。与对照相比，改良土壤中9- 14c -菲活性的恢复较低，特别是在AD + WA处理中，恢复随时间而下降。二氯甲烷（DCM）和羟丙基-β-环糊精（HP-β- cd）的可提取性随土壤-多环芳烃接触时间的增加而降低，其中AD + WA对HP-β- cd的可提取性降低幅度更大。接种系统比未接种系统表现出更短的滞后期，尽管两种接种条件下的细菌数量、矿化率和程度相似。两种接种条件下，AD + WA的矿化程度均较低。该研究为AD、WA和AD + WA如何影响土壤中多环芳烃的生物可及性和矿化动力学提供了新的见解。结果表明，在营养限制条件下，AD和/或WA主要通过生物刺激本地微生物群落来促进9- 14c -菲的生物降解；然而，生物可及性，而不是养分可利用性或微生物丰度，最终限制了降解终点。这些结果强调需要（生物）修复策略，以提高污染物的可用性，而不是仅仅关注营养投入或微生物丰度。

Microplastic research has expanded rapidly, yet substantial methodological variability continues to limit comparability across sediment studies. To characterize current practice and identify priority areas for harmonization, we conducted a systematic literature review (SLR) of 3290 records, from which 37 sediment-focused studies (18 marine, 19 freshwater) met the inclusion criteria. Methods were analyzed using a Reproducible Analytical Pipelines (RAPs) framework encompassing sampling, preparation, detection, and polymer identification. Sampling approaches varied widely: grab samplers dominated (55% of marine and 42% of freshwater studies), while corers (28% and 16%) and manual tools (5% and 16%) were less frequently used. Lower size thresholds spanned

微塑料研究迅速扩大，但实质性的方法可变性继续限制沉积物研究的可比性。为了描述目前的实践并确定协调的优先领域，我们对3290份记录进行了系统的文献综述（SLR），其中37份以沉积物为重点的研究（18份海洋研究，19份淡水研究）符合纳入标准。方法采用可重复分析管道（RAPs）框架进行分析，包括取样、制备、检测和聚合物鉴定。采样方法差异很大：抓斗采样器占主导地位（55%的海洋和42%的淡水研究），而盖（28%和16%）和手动工具（5%和16%）的使用频率较低。较低的尺寸阈值范围为0.1 - 1mm，其中0.1 mm在海洋研究中最常见（45%），在淡水系统中较少（30%）。密度分离几乎是通用的（37项研究中有36项），尽管氯化钠回收高密度聚合物的能力有限，但它在70%以上的工作流程中使用；在不到25%的研究中使用了高密度介质。氧化消化是去除有机物的主要方法（81%）。聚合物的确认绝大多数依赖于μFTIR（35项研究），而拉曼光谱仅出现在4项研究中，主要用于0.1mm的颗粒。总体而言，SLR揭示了方法上的部分趋同，但关键分析参数上的持续分歧，突出了未来协调工作的明确优先事项。

When high accuracy misleads: Stability limits of supervised feature importance in QSAR biodegradation 当高精度误导：QSAR生物降解中监督特征重要性的稳定性限制

Supervised machine learning excels at target prediction but can mischaracterize structure–biodegradability associations when feature importance is treated as ground truth. Using the QSAR Biodegradation dataset (1055 chemicals; 41 descriptors), we compare targeted supervised models (random forest, XGBoost, logistic regression), unsupervised methods (feature agglomeration, highly variable gene selection), and non-targeted supervised approaches (Spearman correlation). We evaluate cross-validated accuracy and ranking stability via a top-10 selection protocol and a leave-top-1-out perturbation. XGBoost attains the highest accuracy (0.8569) yet exhibits ranking instability; random forests are similarly unstable. In contrast, unsupervised and non-targeted supervised methods achieve strong accuracy (≈0.819–0.849) with perfect stability. Results caution against equating high predictive accuracy with reliable feature importance and support stability-aware, label-agnostic selection for interpretable materials science.

监督机器学习在目标预测方面表现出色，但当特征重要性被视为基本事实时，可能会错误地描述结构-生物降解性关联。使用QSAR生物降解数据集（1055种化学物质；41个描述符），我们比较了目标监督模型（随机森林，XGBoost，逻辑回归），无监督方法（特征聚集，高度可变的基因选择）和非目标监督方法（Spearman相关）。我们评估交叉验证的准确性和排名稳定性通过前10名的选择协议和留下前1名的扰动。XGBoost达到最高的精度（0.8569），但表现出排名不稳定；随机森林同样不稳定。相比之下，无监督和非目标监督方法具有较强的准确率（≈0.819-0.849）和较好的稳定性。结果警告不要将高预测准确性与可靠的特征重要性等同起来，并支持可解释材料科学的稳定性意识，标签不可知选择。

While granular activated carbon (GAC) exhibits strong adsorption performance for the removal of pharmaceuticals in ex-situ-controlled environments, its efficiency in the in-situ groundwater remediation is limited. Therefore, this study investigates the efficiency of using colloidal activated carbon (CAC) for the removal of lamotrigine in the lab. The adsorption performance of the CAC for lamotrigine under different operational parameters was evaluated through a series of fixed-bed columns packed with sand and CAC, mimicking a subsurface environment. Breakthrough curves were plotted, and the effect of various factors on lamotrigine removal, including flow rate, CAC dosage, inlet concentration, and background ions, was assessed. Physiochemical characterizations revealed that the CAC is negatively charged, exhibits a microporous structure with a high BET surface area of 1160 m²/g, and is rich in oxygen functional groups. The experimental breakthrough curves were fitted using various models, with the Dose-Response model being the best fit. Lamotrigine was effectively removed by the CAC with a maximum adsorption capacity of 5.76 mg. g-1 at 1 mL/min flowrate, 20 mg/L inlet concentration, 20 cm bed length and 0.6 g CAC dosage. The maximum removal efficiency of lamotrigine was 65 % at a flow rate of 0.5 mL/min. The removal efficiency was found to increase with increasing CAC dosage and decreasing both Lamotrigine initial concentrations and flow rate. The results demonstrate that CAC provides an efficient and cost-effective in-situ remediation of pharmaceutical-contaminated groundwater, at an estimated treatment cost of 13.4 $ per m³.

颗粒活性炭（GAC）在非受控环境中表现出较强的药物吸附性能，但其在地下水原位修复中的效果有限。因此，本研究考察了在实验室中使用胶体活性炭（CAC）去除拉莫三嗪的效率。通过一系列模拟地下环境的固定床柱，模拟砂和CAC对拉莫三嗪的吸附性能，评估了不同操作参数下CAC对拉莫三嗪的吸附性能。绘制了突破曲线，评估了流速、CAC用量、入口浓度和本底离子等因素对拉莫三嗪去除率的影响。理化表征表明，CAC带负电荷，具有高BET表面积（1160 m2/g）的微孔结构，富含氧官能团。实验突破曲线采用多种模型进行拟合，其中剂量-响应模型拟合效果最好。在流量为1 mL/min、进口浓度为20 mg/L、床长为20 cm、CAC用量为0.6 g的条件下，CAC对拉莫三嗪的最大吸附量为5.76 mg. g-1。在0.5 mL/min的流速下，拉莫三嗪的最大去除率为65%。随着CAC投加量的增加、拉莫三嗪初始浓度和流速的降低，去除率提高。结果表明，CAC为药物污染地下水提供了一种高效且具有成本效益的原位修复方法，估计每立方米的处理成本为13.4美元。

PFAS pose significant remediation challenges due to their chemical stability, structural diversity, and strong affinity for soil components. These properties complicate their mobilization from contaminated soils and necessitate compound-specific treatment approaches. Five PFAS compounds (PFBA, PFOA, PFDA, PFOS, and FOSA) were selected to investigate the influence of molecular structure, representing variations in chain length and head group. Electrokinetic (EK) remediation and hydraulic gradient (HG) treatments were applied to soils with organic matter (OM) contents of 5 %, 30 %, and 50 %. Results showed that PFAS removal was highly influenced by the molecular structure of the species. Both EK and HG were effective at mobilizing short-chain PFAS, which are more mobile in porewater. However, moving longer-chain or more strongly sorbing PFAS was more challenging. These compounds responded better to HG due to the stronger advective forces and may require a combination of HG and EK to achieve significant mobilization. Overall, PFOS, FOSA, and PFDA showed limited mobilization under either treatment due to their stronger sorption to soil organic matter, which restricts both electrokinetic and hydraulic transport. These findings highlight the need to align remediation strategies with PFAS physicochemical properties and soil composition to improve field-scale treatment efficiency.

PFAS具有化学稳定性、结构多样性和对土壤组分亲和力强等特点，对土壤修复具有重大挑战。这些特性使其从污染土壤中动员起来变得复杂，需要采用特定的化合物处理方法。选取PFBA、PFOA、PFDA、PFOS和FOSA这5种PFAS化合物，考察其链长和头基的变化对分子结构的影响。对有机质（OM）含量分别为5%、30%和50%的土壤进行了电动（EK）修复和水力梯度（HG）处理。结果表明，PFAS的去除率受物种分子结构的影响较大。EK和HG都能有效调动短链PFAS，后者在孔隙水中更具流动性。然而，移动更长的链或更强的PFAS更具挑战性。由于平流力更强，这些化合物对HG的反应更好，可能需要HG和EK的结合才能实现显著的动员。总体而言，由于PFOS、FOSA和PFDA对土壤有机质的吸收性较强，限制了它们的电动和水力运移，因此在两种处理下，PFOS、FOSA和PFDA的动员都受到限制。这些发现突出表明，需要将修复策略与PFAS的理化性质和土壤组成相结合，以提高田间规模的处理效率。

Increasing calcium (Ca²⁺) concentrations in water systems, largely attributed to industrial effluents and agricultural runoff, present serious environmental and health concerns, including scaling, infrastructure degradation, and elevated risk of kidney stone formation. Conventional calcium removal techniques such as chemical precipitation and reverse osmosis are often energy-intensive and economically unsustainable. This study explores engineered biochars derived from algae and wood as alternative, sustainable materials for Ca²⁺ remediation from aqueous environments. The performance of each biochar was evaluated through a combination of atomistic simulations, batch and continuous-flow adsorption experiments, and gas–liquid–solid phase carbonation tests. Algae-based biochar reduced Ca²⁺ concentrations by up to 47 percent, from 802.4 to 425 mg per liter, outperforming wood-based biochar, which reduced concentrations from 839.5 to 574.3 mg per liter. Both biochars demonstrated significantly higher Ca²⁺ uptake than inert glass bead controls. Carbonation experiments further confirmed the ability of biochar to facilitate calcium carbonate (CaCO₃) precipitation, with algae biochar yielding 762 mg of CaCO₃ and exhibiting substantial surface-scale deposition, suggesting enhanced nucleation and crystal growth. Density Functional Theory (DFT) calculations indicated that nitrogen- and oxygen-containing surface functional groups, particularly amine, pyridine, and carboxyl moieties, are key contributors to Ca²⁺ binding. The adsorption energy analysis supported the superior performance of algae biochar, driven by stronger Ca²⁺ affinity. These results demonstrate the potential of designed biochars as efficient, low-cost materials for water treatment, while supporting sustainable resource management and circular bioeconomy initiatives.

水系统中钙（Ca2+）浓度的增加，主要归因于工业废水和农业径流，带来了严重的环境和健康问题，包括结垢、基础设施退化和肾结石形成风险的增加。传统的除钙技术，如化学沉淀和反渗透，往往是能源密集型和经济上不可持续的。本研究探索从藻类和木材中提取的工程生物炭作为水环境中钙离子修复的替代、可持续材料。通过原子模拟、间歇和连续流吸附实验以及气液固相碳酸化测试来评估每种生物炭的性能。藻类生物炭将Ca2+浓度降低了47%，从每升802.4毫克降至425毫克，优于木质生物炭，将浓度从每升839.5毫克降至574.3毫克。两种生物炭均表现出明显高于惰性玻璃珠对照的Ca2+摄取。碳化实验进一步证实了生物炭促进碳酸钙（CaCO3）沉淀的能力，藻类生物炭产生762 mg CaCO3，并表现出大量的表面沉积，表明生物炭促进了成核和晶体生长。密度泛函理论（DFT）计算表明，含氮和含氧的表面官能团，特别是胺，吡啶和羧基部分，是Ca2+结合的关键贡献者。吸附能分析表明，藻类生物炭具有较强的Ca2+亲和力，具有较好的吸附性能。这些结果证明了设计的生物炭作为高效、低成本的水处理材料的潜力，同时支持可持续资源管理和循环生物经济倡议。

While pesticides are widely used for pest control, they can adversely affect non-target plants by inducing physiological, cytogenetic, anatomical, and biochemical disturbances, many of which are overlooked in standard phytotoxicity evaluations. This study investigated the effects of three soil-applied pesticides aldicarb, carboxin, and metribuzin, on two plant bioassay models, Allium cepa and Vicia faba. Cytogenetic parameters (mitotic index, mitotic phase distribution, and chromosomal aberrations), anatomical structures, and key enzyme activities (peroxidase, phosphatase, esterase, RNase) were assessed. All pesticides caused a concentration-dependent decline in mitotic index and increased chromosomal abnormalities, particularly metaphase suppression, chromosomal fragments, and stickiness. A. cepa was generally more sensitive than V. faba. Metribuzin exhibited the highest genotoxicity, followed by carboxin and aldicarb. Vegetative growth was significantly reduced, with the aldicarb having the strongest inhibitory effect. Metribuzin induced a biphasic (hormetic) response, enhancing growth at low concentrations but inhibiting it at higher doses. Anatomical analysis revealed severe tissue damage, including phloem collapse, cortical degradation, and abnormal vascular development, especially under aldicarb. Enzyme assays showed tissue- and dose-specific disruptions: peroxidase was stimulated at low doses but inhibited at higher ones; esterase and phosphatase were significantly suppressed, especially by metribuzin, while RNase was least affected. These results highlight the need to consider both visible and subtle sub-lethal effects in pesticide risk assessments. A. cepa and V. faba proved to be sensitive and reliable models for ecotoxicological screening, supporting their continued use in regulatory evaluations of pesticide safety.

虽然农药被广泛用于害虫防治，但它们可以通过诱导生理、细胞遗传学、解剖学和生化紊乱对非目标植物产生不利影响，其中许多在标准的植物毒性评估中被忽视。本试验研究了三种土壤施药农药除草剂灭虫威、碳毒素和嘧霉嗪对洋葱和蚕豆两种植物生物测定模型的影响。评估细胞遗传学参数（有丝分裂指数、有丝分裂期分布和染色体畸变）、解剖结构和关键酶活性（过氧化物酶、磷酸酶、酯酶、核糖核酸酶）。所有农药均引起有丝分裂指数的浓度依赖性下降和染色体异常的增加，特别是中期抑制、染色体碎片和黏性。一般而言，cepa比蚕豆更敏感。甲曲霉嗪的遗传毒性最高，其次是碳毒素和涕灭威。对植物生长有明显抑制作用，其中涕灭威的抑制作用最强。metrizin诱导双相（致热）反应，低浓度时促进生长，高剂量时抑制生长。解剖分析显示严重的组织损伤，包括韧皮部塌陷，皮质退化和血管发育异常，特别是在涕灭威下。酶分析显示组织和剂量特异性破坏：过氧化物酶在低剂量时受到刺激，但在高剂量时受到抑制；酯酶和磷酸酶被显著抑制，尤其是被metrizin，而RNase受影响最小。这些结果突出表明，在农药风险评估中需要同时考虑可见和微妙的亚致死效应。cepa和蚕豆被证明是敏感和可靠的生态毒理学筛选模型，支持它们在农药安全性监管评价中的继续使用。

Partially saturated vertical flow (PSVF) wetlands represent a promising, low-cost and easily implemented wastewater treatment technology for on-site treatment in small communities. However, to date, no studies have evaluated PSVF systems under realistic diurnal loading conditions which reflect the fluctuating inflows typical of small-scale household applications. Previous research has largely focused on flow-equalised dosing regimes and the influence of operational parameters, particularly dose volume, has received little attention. To address this gap, this study assesses the treatment performance of three PSVF wetland configurations (zeolite–woodchips, gravel–woodchips, and complete woodchips) subjected to diurnal loading. Three discrete dose volumes (2.75, 5.5, and 11 mm) were applied while maintaining a constant daily hydraulic loading rate of 110 mm d⁻¹, enabling systematic evaluation of how dosing strategies interact with media composition under realistic operating conditions. Organic matter and TSS performance under diurnal loading was similar to that under regular dosing with all PSVF systems achieving removals greater than 95% for cBOD₅ and ∼85% for TSS. Zeolite-woodchip systems consistently removed 97–99% of ammoniacal nitrogen irrespective of dose size, while removal for gravel-woodchip and complete woodchip systems declined with increasing dose size. Both the free-draining (FDL) and saturated layers (SL) contributed to overall TN removal. TN removal peaked at 93% in the complete woodchip system at the smallest diurnal dose but fell below 60% at larger doses due to ammonium breakthrough. In contrast, zeolite-woodchip systems provided 75% TN removal at the large diurnal dose size, comparable to regular hourly dosing operation. Denitrification rates in the woodchip SL were similar across systems and dosing regime falling within the range of 4–6.5 g m⁻³ d⁻¹. Larger applied dose size increased breakthrough of E. coli and phosphorus, due to more rapid percolation of wastewater through the FDL.

部分饱和垂直流（PSVF）湿地是一种有前途的、低成本的、易于实施的污水处理技术，适用于小型社区的现场处理。然而，到目前为止，还没有研究在实际的日负荷条件下评估PSVF系统，这种条件反映了小型家庭应用的典型流入波动。以前的研究主要集中在流量均衡给药制度和操作参数的影响，特别是剂量体积，很少得到重视。为了解决这一空白，本研究评估了三种PSVF湿地配置（沸石-木片，砾石-木片和完整木片）在日负荷下的处理性能。在保持每日110 mm d-1的恒定水力加载率的情况下，应用三种离散剂量体积（2.75、5.5和11 mm），从而能够系统地评估在实际操作条件下，剂量策略如何与介质成分相互作用。在昼夜负荷下，有机物和TSS的性能与常规剂量下相似，所有PSVF系统对cBOD5的去除率均大于95%，对TSS的去除率均大于85%。沸石-木屑体系的氨态氮去除率可达97-99%，而砾石-木屑和完整木屑体系的去除率随剂量的增加而下降。自由排水层（FDL）和饱和层（SL）都有助于总氮的去除。在最小日剂量下，整个木屑体系的TN去除率最高可达93%，但在较大剂量下，由于铵的突破，TN去除率降至60%以下。相比之下，沸石-木屑系统在大日剂量下可以去除75%的TN，与常规的每小时加药操作相当。木屑SL的反硝化速率在不同系统和投加制度下相似，范围在4-6.5 g m-3 d-1。更大的应用剂量增加了大肠杆菌和磷的突破，因为废水通过富底限的渗透速度更快。

Anion exchange resin (AEXR) and granular activated carbon (GAC) adsorbents are effective and well-explored media for the removal of per- and polyfluoroalkyl substances (PFAS) from water streams. As such, these two adsorbent classes have been deemed two of the three best available technologies for water treatment by the United States Environmental Protection Agency. However, the breadth of PFAS studied remains disproportionately focused on long-chain (LC) perfluoroalkyl acids, such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). This work assesses the adsorption efficacy of commercially available AEXR and GAC adsorbents across a series of ultrashort-chain (USC), short-chain (SC), and LC PFAS, with an emphasis on the relatively underexplored USC class. Results uncover the relative adsorption selectivity for AEXR vs GAC, importance of the AEXR functional group, and the impact of competitive inorganic anions across different PFAS and adsorbents. A dynamic column test validates the capacity trends from batch adsorption testing in relation to bed volumes until breakthrough. The structure-property relationships identified expand on the fundamental understanding of adsorbent technology for PFAS remediation applications and highlight the challenges in expanding the application use case particularly for USC PFAS remediation from water.

阴离子交换树脂（AEXR）和颗粒活性炭（GAC）吸附剂是去除水体中全氟烷基和多氟烷基物质（PFAS）的有效介质。因此，这两类吸附剂被美国环境保护局认为是现有的三种最佳水处理技术中的两种。然而，对全氟辛酸的研究仍然不成比例地集中在长链（LC）全氟烷基酸，如全氟辛酸（PFOA）和全氟辛烷磺酸（PFOS）。本研究评估了市售AEXR和GAC吸附剂在一系列超短链（USC）、短链（SC）和LC PFAS上的吸附效果，重点研究了相对未被充分开发的USC类吸附剂。结果揭示了AEXR相对于GAC的相对吸附选择性，AEXR官能团的重要性，以及不同PFAS和吸附剂间竞争性无机阴离子的影响。动态色谱柱测试验证了间歇吸附测试与床层体积相关的容量趋势，直到突破。所确定的结构-性质关系扩展了对PFAS修复应用的吸附剂技术的基本理解，并突出了扩展应用用例的挑战，特别是USC PFAS从水中修复。
