Rapid urbanisation in Low- and Middle-Income Countries (LMICs) has driven the expansion of urban and peri-urban farming to enhance food security. However, these systems are highly vulnerable to contaminated irrigation waters, urban runoff, open defecation and inadequate sanitation, and anthropogenic pollution, such as plastic and microplastic waste. Here, we investigated the role of plastic debris as a reservoir and vector for multidrug-resistant (MDR) enteric bacterial pathogens in a real-world agronomic setting. Focusing on two peri-urban agricultural sites in Dar es Salaam, Tanzania, we analysed 140 environmental samples (soil, water, vegetation, and surface and buried plastic debris) for the presence of four key enteric pathogens: E. coli, Salmonella spp., V. cholerae, and K. pneumoniae. The concentration of total culturable pathogens was higher on plastic debris compared to soil, water and vegetation, with presumptive E. coli loads of ∼1x103 CFU per individual piece of plastic debris. Importantly, plastic debris harboured a greater proportion of MDR strains; specifically, 69% of E. coli isolates were resistant to two or more antimicrobials, with plastics at one site accounting for over half of all MDR E. coli. While MDR E. coli were absent from soil, plastic debris supported strains of E. coli and K. pneumoniae that were resistant to critically important antimicrobials (e.g., ciprofloxacin and cefixime)..This study provides robust evidence that in a real-world setting, plastic waste can act as an ecological reservoir which concentrates and facilitates the survival of MDR pathogens. Therefore, the widespread presence of contaminated plastic in agricultural systems could pose significant occupational health risks for farmers, in addition to a potential environment-to-food risk for consumers.
低收入和中等收入国家(LMICs)的快速城市化推动了城市和城郊农业的扩张,以加强粮食安全。然而,这些系统极易受到灌溉水污染、城市径流、露天排便和卫生设施不足以及人为污染(如塑料和微塑料废物)的影响。在这里,我们研究了在现实世界的农艺环境中塑料碎片作为多药耐药(MDR)肠道细菌病原体的储存库和载体的作用。我们以坦桑尼亚达累斯萨拉姆的两个城郊农业地点为重点,分析了140个环境样本(土壤、水、植被以及地表和掩埋的塑料碎片),以确定存在四种主要肠道病原体:大肠杆菌、沙门氏菌、霍乱弧菌和肺炎克雷伯菌。与土壤、水和植被相比,塑料碎片上的总可培养病原体浓度更高,估计每片塑料碎片上的大肠杆菌负荷为1 × 103 CFU。重要的是,塑料碎片中含有更大比例的耐多药菌株;具体而言,69%的大肠杆菌分离株对两种或更多种抗菌素具有耐药性,其中一个地点的塑料占所有耐多药大肠杆菌的一半以上。虽然土壤中没有耐多药大肠杆菌,但塑料碎片支持大肠杆菌和肺炎克雷伯菌菌株,这些菌株对至关重要的抗菌剂(例如环丙沙星和头孢克肟)具有耐药性。这项研究提供了强有力的证据,证明在现实世界中,塑料废物可以作为一个生态水库,集中并促进耐多药病原体的生存。因此,受污染塑料在农业系统中的广泛存在,除了可能给消费者带来从环境到食品的风险外,还可能给农民带来重大的职业健康风险。

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。

Polyethylene and polylactic acid microplastics affect the migration of Cr(VI) and Cr(III) in acidic clay soil via distinct mechanisms 聚乙烯和聚乳酸微塑料通过不同的机制影响Cr(VI)和Cr(III)在酸性粘土中的迁移

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。

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.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"235 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146129678","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}
