To address this, sustainable solutions like biogas slurry (BS) are needed to enhance soil fertility and soil organic carbon (SOC). This study investigated the effects of conventional nitrogen fertilizer (NPK), standard BS (BS1), and high-nitrogen input BS treatments (BS5, BS7, and BS11) on soil quality, nutrient dynamics, SOC fractions, and environmental risks across soil depths (0–20, 20–40, and 40–60 cm). Field experiments revealed that BS application significantly enhanced the soil quality index (SQI) by 32.5 %–61.6 % in the 0–20 cm soil layer and ecosystem multifunctionality (EMF) by 42.3 %–169.0 % across all layers compared to NPK. Mineral-associated organic carbon (MOC) dominated SOC stabilization (57.2 %–91.3 % of total SOC), with BS11 increasing MOC content by 76.3 % in the 40–60 cm soil layer. High-nitrogen BS treatments increased microbial biomass carbon (MBC) by 318.1 % (BS11) and β-glucosidase activity by 144 % (BS7) in 0–20 cm soil, indicating enhanced soil enzyme activities. However, excessive nitrogen inputs induced nitrate accumulation in the 40–60 cm soil layer, where NO<sub>3</sub><sup>−</sup>-N concentrations surged to 97.2 %–200.6 % above NPK levels. Vertical nutrient migration also triggered subsoil acidification, with the pH decreasing by 5.0 % under the BS11 treatment. These results underscore the dual role of BS: while it enhances SOC stability (via MOC dominance) and multifunctionality, nitrogen inputs must be capped below 300 kg N ha<sup>−1</sup> yr<sup>−1</sup> to mitigate leaching risks. The findings provide actionable insights for optimizing BS applications in sustainable agriculture, balancing soil health improvements with environmental safeguards.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"384 ","pages":"Article 125584"},"PeriodicalIF":8.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 review critically examines the mechanisms, applications, and challenges of microbial consortia for pharmaceutical biodegradation. It emphasizes their synergistic metabolic pathways, such as cross-feeding, co-metabolism, and enzymatic cascades, that enable efficient degradation of complex contaminants. Recent advancements, such as membrane bioreactors, bioaugmentation with genetically engineered consortia, and integrated systems coupling microbial processes with advanced oxidation processes, are reviewed for their potential to enhance treatment efficacy, scalability, and sustainability. Comparative analysis underscores microbial consortia's superiority over single-strain systems and adsorption techniques in treating complex contaminant mixtures, achieving up to 100 % removal efficiency for specific compounds. Persistent challenges include microbial community instability, the toxicity of transformation products, and regulatory constraints related to genetically modified organisms. Strategic solutions are proposed, such as pilot-scale implementation of tailored consortia, Internet of things (IoT)-enabled real-time monitoring, and circular economy approaches for resource recovery. By addressing these challenges, microbial consortia-based biodegradation emerges as a transformative solution for pharmaceutical wastewater treatment, aligning with global sustainability goals.

This paper reviews the status of antibiotic pollution in major countries, territories, and regions worldwide. Addressing the risks cause by antibiotics and their resistance genes and achieving efficient remediation of antibiotic pollutants. Additionally, the study explores the issue of antibiotic use and resistance in detail from a global perspective. It provides a critical scientific foundation for controlling global antibiotic resistance through multi-dimensional integrated analysis. In 2021, 4.71 million deaths globally were attributed to antibiotic resistance, with countries such as India and China being the most affected. It also examined the predominant types and sources of antibiotic pollutants, as well as key remediation technologies for addressing antibiotic contamination. Antibiotics such as amoxicillin and ciprofloxacin are commonly found in surface waters at concentrations ranging from 1 to 120 μg L<sup>−1</sup>. Furthermore, this paper highlighted the distinctive advantages of advanced oxidation processes (AOPs) in addressing antibiotic pollution, demonstrating removal efficiencies exceeding 90 % under optimal conditions. Our review underscored the pivotal role of iron-based materials and porous biochar in AOPs, showing promising results in various environmental settings. Future research should prioritize the development of multifunctional iron-based composites with improved catalytic stability, environmental compatibility, and recyclability. Moreover, expanding the field-scale application of these materials, particularly in low-resource or high-risk regions, will be essential to translate laboratory successes into global impact.

To fulfill this gap, two hydraulic scouring experiments of varying durations were conducted to investigate the effects of water velocity on periphytic algae growing on concrete substrates, and a new algal dynamic model considering detachment threshold and diminishing returns (DDR model) was proposed. Results revealed that water velocity significantly influenced periphytic algal biomass and community composition, identifying a critical value for algal detachment and diminishing returns in scouring effects.
