Neonicotinoid insecticides (NEOs) have become an integral part of the global insecticide market due to their high efficiency and low toxicity. However, their environmental persistence has raised significant ecological concerns. Dongting Lake represents a vital freshwater lake in China, and its ecosystem health directly affects regional ecological balance and people’s livelihoods. This study systematically investigated the occurrence characteristics and ecological risks of NEOs in water bodies and sediments across the Dongting Lake basin. Based on surface water and sediment samples collected from 26 representative sampling sites, this study quantified nine NEOs using liquid chromatography triple quadrupole mass spectrometry. Furthermore, it assessed ecological risks posed by the NEOs using the risk quotient (RQ) method and fugacity modeling. The results revealed the presence of six NEOs in the water bodies: imidacloprid (IMI), acetamiprid (ACE), clothianidin (CLO), thiamethoxam (THIA), flonicamid (FLO), and dinotefuran (DIN). The total concentrations of these six NEOs averaged 275.11 ng/L. Five predominant NEOs (i.e., IMI, THIA, ACE, CLO, and DIN) were identified in the sediments, with a mean concentration of 0.31 ng/g. The NEO concentrations in the water bodies across the Dongting Lake basin increased in the order of the Xiangjiang, Zishui, Yuanjiang, and Lishui rivers (collectively referred to as the Four Rivers), the mainstream of Dongting Lake, the Xinqiang River, the Miluo River, and the Hudu, Ouchi, and Songzi rivers (collectively referred to as the Three Outlets). Sediments from tributaries progressively accumulate in the lake. The ecological risk assessment identified IMI and DIN as the highest-risk compounds (RQ > 1), with high-risk areas concentrated in the mainstream of Dongting Lake and the Ouchi, Miluo, and Hudu rivers. The fugacity model showed that IMI, ACE, and THIA are prone to diffuse from sediments to water bodies in most areas, with fugacity fractions (ff) values of greater than 0.5. In contrast, the mainstream of Dongting Lake acts as a sink of CLO and DIN (ff values: < 0.5). Sediments at the lake’s outlet emerge as an important sink of NEOs. Based on the results of this study, it is advisable to strengthen the supervision of NEO applications in agricultural areas and to implement zonal control strategies. These measures will help reduce ecological risks and protect the safety of water ecosystems in the Dongting Lake region.

新烟碱类杀虫剂因其高效、低毒的特点，已成为全球杀虫剂市场的重要组成部分。然而，它们的环境持久性引起了重大的生态问题。洞庭湖是中国重要的淡水湖，其生态系统健康与否直接关系到区域生态平衡和人民生计。本研究系统调查了洞庭湖流域水体和沉积物中近地天体的赋存特征及生态风险。本研究基于26个代表性采样点的地表水和沉积物样品，采用液相色谱三重四极杆质谱法对9个近地天体进行了定量分析。利用风险商（RQ）法和逸度模型对neo的生态风险进行了评价。结果表明，水体中存在6种neo：吡虫啉（IMI）、啶虫啉（ACE）、噻虫胺（CLO）、噻虫嗪（THIA）、氟虫胺（FLO）和呋虫胺（DIN）。6种neo的总浓度平均值为275.11 ng/L。在沉积物中鉴定出5种优势neo（即IMI、THIA、ACE、CLO和DIN），平均浓度为0.31 ng/g。洞庭湖流域水体中NEO浓度依次为香江、紫水、沅江、丽水（统称“四江”）、洞庭湖干流、新强河、汨罗江、虎都河、大内河、松子河（统称“三口”）。支流的沉积物逐渐积聚在湖中。生态风险评估确定IMI和DIN为风险最高的化合物(RQ >；1)高发区集中在洞庭湖干流和大内河、汨罗河、虎渡河。逸度模型表明，IMI、ACE和THIA在大部分地区容易从沉积物向水体扩散，逸度分数（ff）值大于0.5。相反，洞庭湖干流作为CLO和DIN (ff值：<；0.5)。湖出口处的沉积物是近地天体的重要汇。根据研究结果，建议加强对农业地区近地生物应用的监管，并实施分区控制策略。这些措施将有助于降低生态风险，保护洞庭湖区水生态系统的安全。

To address the critical gap in linking multi-compartmental transfer with risks of trace metals (Cd, Pb, As, Cr, Ni) in mining environments. This study systematically investigated the trans-media migration of Cd, Pb, As, Cr, and Ni in China’s Dexing copper mining district through paired sampling of water-amphibians, soil-earthworms, and air-lichens. Advanced methodologies were employed, including ICP-MS quantification for heavy metals, geochemical indices (Igeo, BCF, BAF) to assess bioavailability, NMDS for source apportionment, and HPLC to detect DNA methylation alterations. Aquatic systems exhibited severe Cd/Pb enrichment (16.25–24.42 μg/L; 11–15× WHO limits), while agricultural soils showed extreme Cd contamination (1.5 mg/kg; 15× background). Biota displayed metal-specific accumulation: frogs achieved BCFs >1,000 for Pb/Cd, earthworms showed pH-modulated BAFs >2.5 for Cd/As, and lichens recorded 100–1,000× atmospheric Cr enrichment. NMDS resolved three contamination pathways: mining-derived Cd/Pb/As (MDS1 = 2.56), atmospheric Cr (PC2 = 1.84), and geogenic Ni. Cd dominated ecological risks (Eri = 554.25; RI 300), while atmospheric Cr drove carcinogenic risks (TCR = 4.11×10⁻⁵) exceeding safety thresholds. The source-media-biota-risk framework pioneers the integration of geochemical transport with epigenetic toxicity biomarkers, demonstrating that sub-lethal Cd/Pb exposure induces genome-wide DNA hypomethylation (2.4%–6.6% reduction; ρ = −0.71 to −0.91). This paradigm shift prioritizes bioavailability-informed regulations over concentration-based metrics, offering actionable strategies for sustainable development goals-aligned mining pollution control.

解决矿山环境中多区间转移与微量金属（Cd、Pb、As、Cr、Ni）风险之间的关键差距。本研究通过对水陆两栖动物、土壤蚯蚓和空气地衣进行配对取样，系统地研究了中国德兴铜矿区Cd、Pb、As、Cr和Ni的跨介质迁移。采用了先进的方法，包括ICP-MS定量测定重金属，地球化学指数（Igeo， BCF， BAF）评估生物利用度，NMDS分析来源，HPLC检测DNA甲基化改变。水体系统Cd/Pb富集严重（16.25 ~ 24.42 μg/L）；11 - 15倍WHO限值)，而农业土壤镉污染严重(1.5 mg/kg；15×背景)。生物群表现出金属特异性积累：青蛙的Pb/Cd达到了BCFs >； 1000，蚯蚓的Cd/As达到了ph调节的bfs >；2.5，地衣记录了100 - 1000倍的大气Cr富集。NMDS分析了三种污染途径：矿源Cd/Pb/As （MDS1 = 2.56）、大气Cr （PC2 = 1.84）和地源Ni。Cd主导生态风险(Eri = 554.25；大气中Cr的致癌风险（TCR = 4.11×10−5）超过安全阈值。源-介质-生物群风险框架率先将地球化学运输与表观遗传毒性生物标志物相结合，表明亚致死Cd/Pb暴露可诱导全基因组DNA低甲基化(减少2.4%-6.6%；ρ =−0.71至−0.91)。这种范式转变优先考虑基于生物利用度的法规，而不是基于浓度的指标，为符合可持续发展目标的采矿污染控制提供了可行的战略。

Fluorine (F)-enriched soils, resulting from geogenic processes or superimposed by anthropogenic activities, have raised significant concerns due to their phytotoxicity and potential threats to human health. Soils in central Guizhou Province exhibit F enrichment, with a mean F concentration of 1067 mg/kg. However, the associated human health risks and geochemical mechanisms driving F enrichment in these soils remain insufficiently understood. In areas with a natural geological background, the average concentrations of F in rice, vegetables, drinking water, and ambient air are 1.54 mg/kg, 0.54 mg/kg, 0.16 mg/L, and 0.29 μg/m³, respectively. In contrast, samples collected near phosphorous chemical plants demonstrate elevated F concentrations: 1.78 mg/kg in rice, 1.53 mg/kg in vegetables, 0.20 mg/L in drinking water, and 11.98 μg/m³ in ambient air. Fluorine in soils was immobilized by apatite and clay minerals, and hardly transferred into water and crops. The fixation of F^- by Ca²⁺ in water and by Fe/Al hydroxides and clay minerals in bottom sediment further reduces F concentrations in water. As a result, hazard quotient (HQ) values below 1.0 indicate negligible fluorine-related health risk in geological background regions. However, ambient air near phosphorous chemical plant exhibited a 41.3-fold increase in F concentration compared to geological background regions. Fluorine-laden emissions can be directly inhaled or deposited on vegetable leaves and orally ingested into human bodies. Improvement of F-rich waste gas disposal and restricted leafy vegetable cultivation are effective measures to reduce F health risks in phosphorous chemical plant regions.

由地质过程产生或人为活动叠加的富氟土壤因其植物毒性和对人类健康的潜在威胁而引起严重关切。黔中土壤富F，平均富F浓度为1067 mg/kg。然而，相关的人类健康风险和驱动这些土壤中氟富集的地球化学机制仍然没有得到充分的了解。在具有自然地质背景的地区，水稻、蔬菜、饮用水和环境空气中氟的平均浓度分别为1.54 mg/kg、0.54 mg/kg、0.16 mg/L和0.29 μg/m3。相比之下，在含磷化工厂附近采集的样品显示F浓度升高：大米中为1.78 mg/kg，蔬菜中为1.53 mg/kg，饮用水中为0.20 mg/L，环境空气中为11.98 μg/m3。土壤中的氟被磷灰石和粘土矿物固定，几乎不转移到水中和作物中。水中的Ca2+和底部沉积物中的Fe/Al氢氧化物和粘土矿物对F-的固定进一步降低了水中的F浓度。因此，危害商（HQ）值低于1.0表明地质背景区域与氟有关的健康风险可以忽略不计。而在含磷化工厂附近的环境空气中，F浓度比地质背景区增加了41.3倍。含氟排放物可直接吸入或沉积在蔬菜叶片上，并经口摄入人体。改善富氟废气处理和限制叶菜种植是降低含磷化工厂区氟健康风险的有效措施。

Xining, a river valley city in China’s arid region, serves as an important industrial hub with a fragile ecological environment. While groundwater heavy metal pollution in this area has drawn increasing concern, the sources and associated human health risks remain inadequately understood. This study analyzed 144 shallow groundwater samples from urban Xining for 14 heavy metals (Fe, Al, B, Mn, Ba, Zn, Pb, Cr⁶⁺, Ni, Cu, Co, Sb, Cd, and As) using the Nemerow comprehensive pollution index, correlation analysis, and the USEPA health risk assessment model. Results identified Fe, Al, B, Mn, Ba, Pb, Cd, and As as the primary pollutants, especially concentrated in river valley plains. These contaminants primarily originate from natural sedimentary conditions and human activities such as industrial and agricultural development. The pollution indices for Al, Pb, Mn, and Fe exceeded clean water thresholds, indicating serious contamination and the need for enhanced regulation. Health risk assessments revealed that children face greater exposure risks than adults, with arsenic and nickel being the main contributors to carcinogenic risk. Sensitivity analysis further showed that As, Fe, and Cd posed the greatest non-carcinogenic and carcinogenic risks, particularly in human-impacted areas such as the Nanchuan and Beichuan valleys and Ganhegou. These findings provide essential insights for groundwater safety management in plateau river valley cities and similar vulnerable regions.

西宁是中国干旱地区的一个河谷城市，是一个重要的工业中心，生态环境脆弱。虽然这一地区的地下水重金属污染日益引起关注，但其来源和相关的人类健康风险仍未得到充分了解。采用Nemerow综合污染指数、相关性分析和USEPA健康风险评价模型，对西宁市144份浅层地下水样品中的14种重金属（Fe、Al、B、Mn、Ba、Zn、Pb、Cr6+、Ni、Cu、Co、Sb、Cd和As）进行了分析。结果表明，主要污染物为Fe、Al、B、Mn、Ba、Pb、Cd和As，主要集中在河谷平原地区。这些污染物主要来自自然沉积条件和工业和农业发展等人类活动。Al、Pb、Mn、Fe污染指标均超过净水阈值，污染严重，需要加强监管。健康风险评估显示，儿童比成人面临更大的接触风险，砷和镍是致癌风险的主要因素。敏感性分析进一步表明，As、Fe和Cd具有最大的非致癌性和致癌性风险，特别是在南川、北川河谷和赣河沟等受人类影响的地区。这些发现为高原河谷城市和类似脆弱地区的地下水安全管理提供了重要见解。

Antibiotics, as emerging pollutants, pose significant risks to aquatic ecosystems and human health by disrupting the endocrine systems of aquatic organisms and affecting ecosystem stability through food chain enrichment. In a study conducted in Hebei Province, China, liquid chromatography-triple quadrupole-linear ion trap mass spectrometry (LC-TQ-LIT-MS) was used to analyze 90 different antibiotics in 31 water samples, including surface water, groundwater, and waste leachate from three urban landfills. This analysis included hormones, broad-spectrum antimicrobials, macrolides, tetracyclines, β-lactams, sulfonamides, and quinolones. The study’s results indicated that quinolones, β-lactams, and macrolides were the most frequently detected substances in the landfills. It is noteworthy that the concentrations of these antibiotics varied significantly among different cities, reflecting local production and living characteristics. The results of the tests showed that the concentration of amoxicillin was 1171 ng/L in surface water, 811 ng/L in groundwater, and 1926 ng/L of ciprofloxacin in waste leachate. Furthermore, a consistent pattern was observed between the compounds present in the leachate, groundwater, and surface water at the three sites. Risk assessments revealed that the ecological risk was higher for surface water and lower for groundwater. This study is the first to systematically analyze the pollution status of antibiotics and hormones in the water around the landfill in Hebei Province, which not only fills the blank of groundwater-related research in Hebei Province but also provides key data support and theoretical basis for local groundwater hydrological and environmental detection and pollution prevention.

抗生素作为新兴污染物，通过扰乱水生生物的内分泌系统，通过食物链富集影响生态系统的稳定性，对水生生态系统和人类健康构成重大风险。在中国河北省进行的一项研究中，采用液相色谱-三重四极杆线性离子阱质谱（lc - tq - litt - ms）分析了31个水样中的90种不同抗生素，包括来自三个城市垃圾填埋场的地表水、地下水和垃圾渗滤液。该分析包括激素、广谱抗菌剂、大环内酯类、四环素类、β-内酰胺类、磺胺类和喹诺酮类药物。研究结果表明，喹诺酮类、β-内酰胺类和大环内酯类是垃圾填埋场中最常检测到的物质。值得注意的是，这些抗生素在不同城市的浓度差异较大，反映了当地的生产和生活特点。试验结果表明，地表水中阿莫西林浓度为1171 ng/L，地下水中为811 ng/L，垃圾渗滤液中环丙沙星浓度为1926 ng/L。此外，在三个地点的渗滤液、地下水和地表水中存在的化合物之间观察到一致的模式。风险评价结果表明，地表水生态风险较高，地下水生态风险较低。本研究首次系统分析了河北省垃圾填埋场周边水体中抗生素和激素的污染状况，不仅填补了河北省地下水相关研究的空白，也为当地地下水水文环境检测和污染防治提供了关键数据支持和理论依据。

Human activities are closely related to geological environments or those influenced by geological factors, which can significantly impact human health. Previous studies have predominantly focused on isolated spheres or single environmental indicators, lacking research on the multifactorial influences affecting the overall geographic environment. From the “One Health” perspective, this paper synthesizes natural environmental factors across the lithosphere, hydrosphere, atmosphere, and pedosphere, encompassing the sources, forms, concentrations, and bioavailability of chemical elements, as well as pollutants and their associations with human health. Comprehensive natural environmental factors, based on GeoHealth, are intimately connected to human health. Under the pressures of future population growth and rapid industrial development, the relationship between the global geological environment and human health will become increasingly prominent. Therefore, it is crucial to pay close attention to health-based thresholds and promptly implement pollution prevention and control measures.

人类活动与地质环境或受地质因素影响的活动密切相关，对人类健康有重大影响。以往的研究主要集中在孤立的领域或单一的环境指标上，缺乏对影响整体地理环境的多因素影响的研究。本文从“同一个健康”的角度，综合了岩石圈、水圈、大气、土壤圈的自然环境因子，包括化学元素的来源、形态、浓度、生物利用度、污染物及其与人类健康的关系。以地球健康为基础的综合自然环境因素与人类健康密切相关。在未来人口增长和工业快速发展的压力下，全球地质环境与人类健康的关系将日益突出。因此，密切关注健康阈值，及时实施污染防治措施至关重要。
