Intensive agriculture aggravates soil acidification and heavy metal contamination. Biochar and its composites are cost-effective, carbon-rich amendments that can influence both heavy metal and soil carbon cycling, yet their synergistic mechanisms remain unclear. In this study, a combination of the diffusive gradient in thin films (DGT) technique, Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS), and high-throughput sequencing was applied to investigate the effects of various biochar-based amendments: plain biochar, bacteria-inoculated biochar, and biochar combined with oyster shell powder on copper (Cu) stabilization and carbon dynamics in acidic orchard soils. All amendments significantly raised soil pH (by 1.03–2.54 units) and organic matter content, while reducing bioavailable Cu (DGT-Cu) by 60%–73%. Bacteria-inoculated biochar exhibited superior performance, lowering microbial metabolic quotient (qCO₂) by 44%, enriching functional microbial taxa (e.g., Bacillus spp., by 7-fold), and enhancing soil enzyme activity. These shifts coincided with an 8% decrease in recalcitrant compounds (e.g., lignin, tannin) and a 6% increase in labile protein/lipid fractions of dissolved organic matter (DOM), indicating accelerated microbial turnover of stable carbon pools. Statistical analyses indicated that Cu bioavailability was primarily controlled by soil properties (e.g., pH), while qCO₂ was mainly driven by microbial traits like community structure and microbial biomass carbon. Notably, pH also indirectly shapes microbial processes. This study reveals a mechanistic linkage between Cu immobilization and carbon sequestration, highlighting the dual regulatory role of soil properties and microbial processes. These findings provide new insights into the ecological restoration and sustainable management of contaminated agricultural soils.

集约化农业加剧了土壤酸化和重金属污染。生物炭及其复合材料是具有成本效益的富碳修正物，可以影响重金属和土壤碳循环，但其协同机制尚不清楚。本研究采用薄膜扩散梯度（DGT）技术、傅里叶变换离子回旋共振质谱（FT-ICR MS）和高通量测序相结合的方法，研究了不同生物炭基改性剂：普通生物炭、细菌接种生物炭和生物炭与牡蛎壳粉复合对酸性果园土壤中铜（Cu）稳定和碳动态的影响。所有修正均显著提高土壤pH值（1.03 ~ 2.54单位）和有机质含量，降低生物有效铜（DGT-Cu） 60% ~ 73%。细菌接种的生物炭表现出优异的性能，降低了44%的微生物代谢商（qCO2），丰富了7倍的功能微生物类群（如芽孢杆菌），提高了土壤酶活性。这些变化与顽固性化合物（如木质素、单宁）减少8%和溶解有机物（DOM）的不稳定蛋白质/脂质部分增加6%同时发生，表明稳定碳库的微生物周转加速。统计分析表明，Cu的生物有效性主要受土壤性质（如pH）的控制，而qCO2主要受群落结构和微生物生物量碳等微生物性状的控制。值得注意的是，pH值也间接影响微生物的过程。该研究揭示了铜固定与碳固存之间的机制联系，强调了土壤性质和微生物过程的双重调节作用。这些发现为污染农业土壤的生态恢复和可持续管理提供了新的见解。

The lack of toolkits for assessing the shipping-related atmospheric impacts limits China's ability to formulate effective shipping emissions control policies to address coastal air pollution and mitigate related health burdens. Here, we developed a deep learning model, DeepShip, to efficiently predict shipping-related PM_2.5 concentrations and further coupled it with a multi-task learning and generative-adversarial training strategy to enhance the sensitivity of the data-driven model to variations in small emission sources. Based on DeepShip, we comprehensively analyzed the response of shipping-related PM_2.5 to changes in anthropogenic emissions based on 210 scenarios involving emission reductions of shipping and land-based sectors. Furthermore, sulfur and nitrogen emission control scenarios that China might implement in the future were established to assess their cost, air quality improvement, and health benefits. We found that shipping-related PM_2.5 shows an almost linear relationship with shipping emissions, while exhibiting a nonlinear relationship with land-based emissions. Considering the cost and environmental-health benefits, future shipping emissions control should prioritize progressively enhancing the NO_x emission standard while coordinating with land-based emission reductions.

缺乏评估航运相关大气影响的工具包，限制了中国制定有效的航运排放控制政策以解决沿海空气污染和减轻相关健康负担的能力。在这里，我们开发了一个深度学习模型DeepShip，以有效地预测与航运相关的PM2.5浓度，并进一步将其与多任务学习和生成对抗训练策略相结合，以提高数据驱动模型对小排放源变化的敏感性。基于DeepShip，我们基于210种涉及航运和陆基部门减排的情景，综合分析了航运相关PM2.5对人为排放变化的响应。此外，还建立了中国未来可能实施的硫和氮排放控制情景，以评估其成本、空气质量改善和健康效益。我们发现，与航运相关的PM2.5与航运排放几乎呈线性关系，而与陆地排放呈非线性关系。考虑到成本和环境健康效益，未来的船舶排放控制应优先考虑逐步提高氮氧化物排放标准，同时与陆地减排相协调。

Mercury pollution, in conjunction with other contaminants, hampers progress toward the United Nations Sustainable Development Goals. The Minamata Convention on Mercury, which came into force in 2017, represents a critical step in combating this global issue. However, evaluating its effectiveness faces a major challenge, that is, establishing a clear link between reduced mercury emissions and lessened human exposure to neurotoxic methylmercury. Here, we propose that a previously overlooked methylmercury detoxification pathway in primary producers holds the potential to bridge the gaps in the emission-exposure nexus. A comprehensive understanding of this in vivo methylmercury demethylation and mercury reduction will enhance the effectiveness of global mercury mitigation efforts, accelerating our pace toward a sustainable future.

汞污染与其他污染物一道阻碍了在实现联合国可持续发展目标方面取得进展。2017年生效的《关于汞的水俣公约》是应对这一全球性问题的关键一步。然而，评估其有效性面临着一项重大挑战，即在减少汞排放与减少人类接触神经毒性甲基汞之间建立明确的联系。在这里，我们提出，以前被忽视的初级生产者的甲基汞解毒途径具有弥合排放-暴露关系差距的潜力。全面了解这种体内甲基汞去甲基化和汞减少将提高全球汞减缓努力的有效性，加快我们迈向可持续未来的步伐。

Global warming results in more field soil suffering freeze-thaw cycles (FTCs). The environmental risk of microplastics—recognized as a global emerging contaminant—in soils undergoing FTCs remains unclear. In this study, the combined effects of FTCs and poly(butylene adipate-co-terephthalate) (PBAT) microplastics on microbial degradation of atrazine in Mollisols were investigated. Freeze-thaw cycles, rather than microplastics, significantly inhibited the biodegradation of atrazine in soil, with average inhibition ratios of 33.69% and 4.99% for FTCs and microplastics, respectively. Thawing temperature was the main factor driving the changes in soil microbial community structures and the degradation of atrazine. The degradable microplastics with an amendment level of 0.2% had different and limited effects on the dissipation of atrazine under different modes of FTCs. Among the four modes, microplastics only showed a trend toward promoting atrazine degradation under high-frequency and high-thawing-temperature FTCs. Across all modes, microplastics altered microbial interactions and ecological niches that included affecting specific bacterial abundance, module keystone species, microbial network complexity, and functional genes in soil. There's no synergistic effect between microplastics and FTCs on the degradation of atrazine in soil within a short-term period. This study provides critical insights into the ecological effects of the new biodegradable mulch film-derived microplastics in soil under FTCs.

全球变暖导致更多的农田土壤遭受冻融循环（FTCs）。微塑料被认为是一种全球性的新兴污染物，其在正在进行FTCs的土壤中的环境风险尚不清楚。本研究研究了氟氯化碳和聚己二酸丁二酯（PBAT）微塑料对mollisol中阿特拉津的微生物降解的联合影响。冻融循环显著抑制土壤中阿特拉津的生物降解，而非微塑料，对FTCs和微塑料的平均抑制率分别为33.69%和4.99%。解冻温度是影响土壤微生物群落结构变化和阿特拉津降解的主要因素。改性量为0.2%的可降解微塑料在不同模式下对阿特拉津的耗散效果不同且有限。在四种模式中，微塑料仅在高频和高解冻温度FTCs下表现出促进阿特拉津降解的趋势。在所有模式中，微塑料改变了土壤中微生物的相互作用和生态位，包括影响特定细菌丰度、模块关键物种、微生物网络复杂性和功能基因。微塑料与氟氯化碳在短期内对土壤中阿特拉津的降解没有协同效应。这项研究为新型可生物降解地膜衍生微塑料在FTCs下土壤中的生态效应提供了重要见解。

China has experienced an initial increase and a subsequent decrease in fine particulate matter (PM_2.5) concentrations since the early 21st century, with substantial heterogeneity across different source contributions. This study developed a source-oriented CMAQ model to construct a source-resolved PM_2.5 concentration database for China during 2000–2020. Subsequently, source-specific health risks and the contributions of key driving factors were systematically evaluated using the piling-up decomposition method. The results indicate that anthropogenic emissions, particularly from industrial sources, were the primary drivers of both the increase in PM_2.5 from 2000 to 2012 (51.8%) and the subsequent decrease from 2012 to 2020 (47.6%). Currently, industrial sources remain the largest contributor to PM_2.5 (about 32%), followed by residential (about 22%) and transportation sources (about 13%). Implementation of two-phase air pollution control measures led to a 20.4% reduction in national premature mortality attributable to PM_2.5 from 2012 to 2020, although 10.6% of this benefit was offset by changes in population and baseline mortality rates. Throughout 2000–2020, health risks associated with anthropogenic sources consistently exceeded their proportional contribution to PM_2.5, primarily because these emissions are concentrated in densely populated areas. These findings underscore that, in addition to implementing region-specific emission reduction policies, maintaining stringent controls on anthropogenic emissions, particularly from industrial and transportation sources, is crucial to maximizing future health benefits.

自21世纪初以来，中国细颗粒物（PM2.5）浓度呈先增后降的趋势，且不同来源的贡献存在很大的异质性。本研究建立了面向源的CMAQ模型，构建了2000-2020年中国PM2.5源分辨浓度数据库。随后，采用堆积分解法系统评价了源特异性健康风险和关键驱动因素的贡献。结果表明，人为排放，特别是工业排放，是2000 - 2012年PM2.5增加（51.8%）和随后2012 - 2020年下降（47.6%）的主要驱动因素。目前，工业来源仍然是PM2.5的最大来源（约32%），其次是住宅来源（约22%）和交通来源（约13%）。2012年至2020年，两阶段空气污染控制措施的实施使PM2.5导致的全国过早死亡率降低了20.4%，尽管其中10.6%的效益被人口和基线死亡率的变化所抵消。在2000-2020年期间，与人为源相关的健康风险始终超过其对PM2.5的比例贡献，主要是因为这些排放集中在人口稠密地区。这些调查结果强调，除了执行特定区域的减排政策外，严格控制人为排放，特别是来自工业和运输来源的排放，对于最大限度地提高未来的健康效益至关重要。

Exposure to microplastics (MPs) has emerged as a potential threat to chronic respiratory health. However, the association between MPs exposure and allergic rhinitis (AR) in children remains unclear. We evaluated the association between MP exposure and the prevalence of AR in children. We measured 11 types of MPs in bronchoalveolar lavage fluid (BALF) collected from 207 children aged 1–16 years using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) in 2023. Logistic regression models were employed to evaluate the association between MP concentration and prevalence of AR. Polyamide 66 (PA66), polyethylene (PE), polyvinyl chloride (PVC), and polystyrene (PS) were the predominant types detected, with median concentrations of 2.33, 0.45, 0.38, and 0.08 μg/mL in BALF, respectively. Higher concentrations of PA66 were associated with an increased prevalence of AR in all children, with odds ratios (ORs) of 3.00 (95% CI: 1.23, 7.34) after adjusting for potential confounders, indicating a statistically significant association (α < 0.05). Higher concentrations of total MP exposure (P_overall = 0.012, P_nonlinear = 0.310) and PA66 exposure (P_overall = 0.012, P_nonlinear = 0.951) were significantly associated with the prevalence of AR in children aged ≤6 years but not in those aged >6 years. Our findings suggest that exposure to MPs, particularly PA66, may be associated with a higher risk of AR in younger children. Further large-scale, community-based pediatric cohort studies are needed to elucidate the underlying mechanisms.

暴露于微塑料（MPs）已成为慢性呼吸道健康的潜在威胁。然而，MPs暴露与儿童变应性鼻炎（AR）之间的关系尚不清楚。我们评估了MP暴露与儿童AR患病率之间的关系。我们于2023年采用热解-气相色谱/质谱法（Py-GC/MS）检测了207例1-16岁儿童支气管肺泡灌洗液（BALF）中的11种MPs。采用Logistic回归模型评价MP浓度与AR患病率之间的关系。BALF中检测到的主要类型为聚酰胺66 （PA66）、聚乙烯（PE）、聚氯乙烯（PVC）和聚苯乙烯（PS），中位浓度分别为2.33、0.45、0.38和0.08 μg/mL。在所有儿童中，PA66浓度较高与AR患病率增加相关，校正潜在混杂因素后的比值比（or）为3.00 (95% CI: 1.23, 7.34)，表明具有统计学意义的相关性（α < 0.05）。较高浓度的总MP暴露（Poverall = 0.012， p非线性= 0.310）和PA66暴露（Poverall = 0.012， p非线性= 0.951）与≤6岁儿童AR患病率显著相关，但与6岁儿童AR患病率无关。我们的研究结果表明，暴露于MPs，特别是PA66，可能与年幼儿童发生AR的高风险有关。需要进一步的大规模、以社区为基础的儿科队列研究来阐明潜在的机制。

Our findings suggest that exposure to MPs, particularly PA66, may be associated with a higher risk of AR in younger children. Further large-scale, community-based pediatric cohort studies are needed to elucidate the underlying mechanisms.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 4","pages":"Article 100193"},"PeriodicalIF":17.6,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
