Pharmaceutically active compounds (PhACs) are recognized as important emerging pollutants in aquatic environments. Despite growing concern, an increasing number of new pharmaceuticals are being authorized each year, reaching the environment and compromising the quality and health of ecosystems. However, comprehensive multi-matrix investigations integrating water, sediments, biota, and wastewater systems remain scarce. In this study, a comprehensive HRMS-based suspect screening workflow was implemented using ultra-high performance liquid chromatography coupled with high-resolution mass spectrometry (UPLC-HRMS). Through a multi-compartment approach involving water (n=89), sediments (n=28), fish (n=24), wastewater (n=16), and sewage sludge (n=16) matrices collected during 2020-2022, this study identified 153 PhACs (136 active ingredients and 17 metabolites or transformation products). Cardiovascular, psychotropic, pain management, and other nervous system drugs were the dominant therapeutic families, accounting for 63% of all identifications. Surface water contained the highest number of compounds (122), followed by effluents (85). Although influents presented fewer compounds, they showed significantly higher total input (p < 0.05). Solid matrices such as sediments and sludge accumulated highly hydrophobic substances (e.g., telmisartan, citalopram), whereas aqueous matrices contained more polar compounds (e.g., tramadol) and metabolites. Fish exhibited the lowest number of PhACs (11). Regarding spatial distribution, sites more strongly influenced by human activities displayed higher (p < 0.05) normalized areas and number of compounds. Overall, this study provides one of the most comprehensive multi matrix suspect screening assessments of PhACs to date. The holistic evaluation of the riverine ecosystem highlights the value of HRMS based workflows for identifying and prioritizing emerging contaminants, supporting the development of regulatory strategies to control pharmaceutical pollution and enabling early detection of newly marketed drugs.
药物活性化合物(PhACs)是水生环境中重要的新兴污染物。尽管日益引起关注,但每年仍有越来越多的新药获得批准,影响环境并损害生态系统的质量和健康。然而,综合水、沉积物、生物群和废水系统的综合多基质研究仍然很少。在本研究中,采用超高效液相色谱-高分辨率质谱(UPLC-HRMS)实现了基于hrms的嫌疑人筛选工作流程。通过对2020-2022年期间收集的水(n=89)、沉积物(n=28)、鱼(n=24)、废水(n=16)和污水污泥(n=16)基质的多室方法,本研究确定了153种PhACs(136种有效成分和17种代谢物或转化产物)。心血管、精神药物、疼痛治疗和其他神经系统药物是主要的治疗家族,占所有鉴定的63%。地表水含有的化合物最多(122种),其次是污水(85种)。虽然进水中化合物含量较少,但总输入量显著增加(p < 0.05)。固体基质如沉积物和污泥积累了高度疏水性物质(如替米沙坦、西酞普兰),而水基质含有更多极性化合物(如曲马多)和代谢物。鱼类中PhACs的数量最少(11个)。在空间分布上,受人类活动影响越强烈的地点,其归一化面积和化合物数量越高(p < 0.05)。总的来说,这项研究提供了迄今为止最全面的PhACs多矩阵可疑筛查评估之一。河流生态系统的整体评估强调了基于HRMS的工作流程的价值,它可以识别和优先处理新出现的污染物,支持制定控制药物污染的监管战略,并能够早期发现新上市的药物。

The increasing consumption of plastic in our society has led to the dissemination of microplastics in the environment, which, by diffusing into the food chain and across terrestrial compartments, results in human exposure to a wide diversity of particulate plastics. This study aimed to elucidate the impact of a realistic mixture of microplastics on the colon. Environmental samples composed of the four predominant polymers were cryoground. Irregularly shaped micro-fragments of polypropylene, polyethylene terephthalate, polystyrene, and polyethylene (45–100 μm) were mixed and incorporated into the mouse diet at three doses (5, 50, and 500 μg/g) to reproduce the proportions found in human stool. A 30-day exposure to the microplastic mixture induced dose-dependent alterations of the colonic transcriptome, with downregulation of heat-shock proteins. T-cell activation and cytokine-cytokine receptor interaction signaling pathways were dysregulated at all three doses. This was accompanied by immune dysfunction in the mesenteric lymph nodes. A 30-day exposure worsened the development of colonic inflammation in the DSS-induced colitis model, with increases in the colon weight-to-size ratio, myeloperoxidase activity, and cytokines transcript levels at the medium dose. A 75-day exposure exacerbated tumorigenesis in the AOM/DSS-induced colorectal cancer model at the high dose, as evidenced by worse endoscopic, macroscopic, and histologic scores of tumorigenesis, and increased Cyclin D1 and MYC protein expression. In mice, oral exposure to an environmentally sourced microplastic mixture that reproduces the size, shape, polymer types, and relative proportions of microplastics detected in human stool leads to colonic transcriptomic dysregulation and increased susceptibility to inflammation and tumorigenesis.
在我们的社会中,塑料消费的增加导致了微塑料在环境中的传播,这些微塑料通过扩散到食物链和陆地隔间,导致人类接触到各种各样的塑料微粒。本研究旨在阐明微塑料的真实混合物对结肠的影响。由四种主要聚合物组成的环境样品是冷冻的。将形状不规则的聚丙烯、聚对苯二甲酸乙二醇酯、聚苯乙烯和聚乙烯微碎片(45-100 μm)混合并以三种剂量(5、50和500 μg)加入小鼠饮食中,以重现人类粪便中的比例。暴露于微塑料混合物30天诱导结肠转录组的剂量依赖性改变,热休克蛋白下调。在所有三种剂量下,t细胞活化和细胞因子-细胞因子受体相互作用信号通路均失调。这伴有肠系膜淋巴结的免疫功能障碍。在dss诱导的结肠炎模型中,暴露30天恶化了结肠炎症的发展,在中等剂量下,结肠重量与大小比、髓过氧化物酶活性和细胞因子转录水平增加。高剂量暴露75天加剧了AOM/ dss诱导的结直肠癌模型的肿瘤发生,内窥镜、宏观和组织学评分更差,Cyclin D1和MYC蛋白表达增加。在小鼠中,口服暴露于一种环境来源的微塑料混合物,这种混合物复制了人类粪便中检测到的微塑料的大小、形状、聚合物类型和相对比例,导致结肠转录组失调,增加了对炎症和肿瘤发生的易感性。

Muddy and sandy coastlines account for approximately 45% of the world's ice-free coastlines, facing significant ecological risks from antibiotic pollution due to overuse. This study elucidates how fundamental differences in sediment composition govern the distinct transport and fate of antibiotics in these contrasting coastal systems. Muddy coasts primarily consisted of fine-grained sediments with higher water contents, whereas sandy coasts are characterized by coarse-grained sand and gravel with better water permeability. Porewater acts as a bridge between overlying water and sediment, playing a crucial role in contaminant transport. This study compared the antibiotic pollution patterns and revealed the regulatory mechanisms of coastal sediment on the antibiotic source - sink processes. Results showed that antibiotic concentrations in the porewater of mangroves (18.4-182 ng/L) were significantly higher than those (13.3-30.4 ng/L) in sandy beaches. However, higher proportions of tetracyclines in sandy sediment than muddy sediment were found. Spatially, the lowest antibiotic concentrations within the mangrove ecosystem occurred in natural areas. Source analysis indicated that antibiotics in mangroves were predominantly derived from localized sewage and wastewater, whereas in sandy beaches, they were primarily attributed to non-point sources via rainfall runoff and tidal forcing. Our findings revealed that sediment properties govern the spatial distribution and ecological risks of antibiotics in coastal zones. The contrasting retention capacities of muddy and sandy coasts dictate divergent ecological risk patterns. An accurate assessment of the environmental risks posed by antibiotics must account for their specific behavior in water-sediment systems. Consequently, management for muddy coasts should emphasize source control, while for sandy coasts, priority should be given to intercepting transport pathways.
泥泞和沙质海岸线约占世界无冰海岸线的45%,由于过度使用抗生素而面临严重的生态风险。这项研究阐明了沉积物组成的根本差异如何在这些对比鲜明的海岸系统中控制抗生素的独特运输和命运。泥质海岸主要由细粒沉积物组成,含水量较高;砂质海岸主要由粗粒砂砾组成,透水性较好。孔隙水作为上覆水和沉积物之间的桥梁,在污染物的运输中起着至关重要的作用。本研究比较了海岸带沉积物对抗生素源-汇过程的影响,揭示了海岸带沉积物对抗生素源-汇过程的调控机制。结果表明:红树林孔隙水中抗生素浓度(18.4 ~ 182 ng/L)显著高于沙滩孔隙水中抗生素浓度(13.3 ~ 30.4 ng/L);然而,沙质沉积物中四环素的比例高于泥质沉积物。从空间上看,红树林生态系统中抗生素浓度最低的是自然区域。来源分析表明,红树林中的抗生素主要来源于局部的污水和废水,而在沙滩中,抗生素主要归因于降雨径流和潮汐强迫等非点源。研究结果表明,沉积物性质决定了海岸带抗生素的空间分布和生态风险。淤泥质海岸和沙质海岸的不同截留能力决定了不同的生态风险模式。抗生素造成的环境风险的准确评估必须考虑到它们在水-沉积物系统中的具体行为。因此,对泥质海岸的管理应强调源头控制,而对沙质海岸的管理应优先考虑拦截运输途径。

The European common toad (Bufo bufo) is undergoing widespread population declines, potentially influenced by multiple environmental stressors, including chemical pollution. This study aimed to link the toad population status and contaminant levels in 20 breeding ponds in Flanders (Belgium). A multi-contaminant analytical approach was applied, using solid-phase extraction (SPE) combined with advanced instrumental methods: ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC–MS/MS) for pesticides and mycotoxins, UHPLC-Orbitrap-high resolution MS for pharmaceuticals, inductively coupled plasma-optical emission spectrometry (ICP-OES) and ICP-MS for high and low-concentrated metals, respectively, and ion chromatography (IC) for nutrients. Across ponds, 25 pesticides, 11 mycotoxins, 13 antimicrobial drugs, 5 antiparasitic drugs, and 11 metals were detected, reaching concentrations up to 114 ng/L (pesticides), 88.2 ng/L (mycotoxins), 837 ng/L (antimicrobials), 26.8 ng/L (antiparasitic drugs), and 7382 μg/L (metals). Temporal variability was pronounced, with episodic increases in pesticide and metal levels, declining nitrate and sulphate concentrations, and increasing enniatin levels from March to June. Despite frequent co-contamination, no direct relationship was observed between individual contaminant levels and toad population status. These findings suggest that population declines are unlikely to be driven by a single substance, but rather by combined pressures associated with complex contaminant mixtures and other environmental stressors.
欧洲蟾蜍(Bufo Bufo)正在经历广泛的数量下降,可能受到多种环境压力因素的影响,包括化学污染。本研究旨在了解比利时法兰德斯20个养殖池塘中蟾蜍种群状况与污染物水平的关系。采用固相萃取(SPE)结合先进的仪器分析方法,对农药和真菌毒素进行了超高效液相色谱-串联质谱分析(UHPLC-MS /MS),对药物进行了超高效液相色谱-高分辨率质谱分析(uhplc - orbitrap -高分辨率质谱分析),对高、低浓度金属分别进行了电感耦合等离子体光学发射光谱分析(ICP-OES)和ICP-MS分析,对营养物质进行了离子色谱分析(IC)。共检出25种农药、11种真菌毒素、13种抗菌药物、5种抗寄生虫药物和11种金属,浓度分别为114 ng/L(农药)、88.2 ng/L(真菌毒素)、837 ng/L(抗菌药物)、26.8 ng/L(抗寄生虫药物)和7382 μg/L(金属)。从3月到6月,时间变化明显,农药和金属含量断断续续地增加,硝酸盐和硫酸盐浓度下降,enniatin含量增加。尽管经常发生共同污染,但没有观察到单个污染物水平与蟾蜍种群状况之间的直接关系。这些发现表明,数量下降不太可能是由单一物质驱动的,而是由复杂污染物混合物和其他环境压力因素相关的综合压力驱动的。

The coexistence of microplastics (MPs) and heavy metals in agricultural soils leads to complex interactions during their adsorption and migration processes. Understanding their fate under realistic soil conditions is crucial for assessing the associated environmental risks. Therefore, virgin and aged polyethylene (PE) and polylactic acid (PLA) MPs were used to investigate their influence on the adsorption and migration of chromium (Cr) in unsaturated steady-state soils via batch and column experiments. Batch experiments revealed that soil adsorbed less Cr(VI) than Cr(III) (0.44 vs. 1.45 mg/g). The addition of MPs inhibited Cr adsorption (specifically, 0.40 and 1.23 mg/g for Cr(VI) and Cr(III), respectively, at 7% MP addition), with adsorption capacity decreasing as MP dosage increased. Column experiments showed Cr(VI) reached adsorption equilibrium faster than Cr(III) (25 vs. 41 pore volumes); its migration was primarily controlled by soil hydraulic conditions, and MPs exerted an inhibitory effect. In contrast, Cr(III) migration was predominantly governed by adsorption, and MP addition promoted its migration. Regarding the MPs themselves, PE exhibits greater migration capacity, which decreased with aging, whereas PLA showed the opposite trend. Interestingly, the presence of Cr(III) reduces the migration of MPs compared to Cr(VI). These findings clarify the effects and mechanisms of MPs on Cr migration under realistic soil conditions, and enhance the understanding of migration dynamics and environmental fate of coexisting pollutants.
微塑料与重金属在农业土壤中的共存,导致它们在吸附和迁移过程中发生复杂的相互作用。了解它们在现实土壤条件下的命运对于评估相关的环境风险至关重要。因此,采用未加工聚乙烯(PE)和陈化聚乙烯(PLA) MPs,通过批量和柱状实验研究了它们对非饱和稳态土壤中铬(Cr)的吸附和迁移的影响。批量试验结果表明,土壤对Cr(VI)的吸附量小于Cr(III) (0.44 vs. 1.45 mg/g)。MP的加入抑制了Cr的吸附(在MP添加量为7%时,Cr(VI)和Cr(III)的吸附量分别为0.40和1.23 mg/g),吸附量随MP添加量的增加而降低。柱实验表明,Cr(VI)比Cr(III)更快达到吸附平衡(25比41孔体积);其迁移主要受土壤水力条件控制,MPs具有抑制作用。相反,Cr(III)的迁移主要受吸附控制,MP的加入促进了其迁移。就MPs本身而言,PE表现出更大的迁移能力,随着年龄的增长而下降,而PLA表现出相反的趋势。有趣的是,与Cr(VI)相比,Cr(III)的存在减少了MPs的迁移。这些发现阐明了实际土壤条件下MPs对Cr迁移的影响及其机制,增强了对共存污染物迁移动力学和环境命运的认识。
