As emerging contaminants, microplastic (MP) pollution in freshwater environments has received increasing attention due to their potential hazardous effects on human and environmental health. However, there is still limited understanding on variability of MP diversity and distribution patterns in riverine ecosystem compartments and field data are also lacking. This has hindered understanding and science-based information regarding mechanisms of fate and transport in freshwater environments. Hence, our study focused on reporting variability of MP diversity and distribution patterns in riverine ecosystem compartments. By undertaking MP community analyses, we found that distribution and variation in MP characteristics and communities among ecosystem compartments differed significantly. Moreover, structural characteristics of MP communities across compartments were distinct but not fully isolated, reflecting a balance between dispersion and niche differentiation (environmental filtering). Specifically, surface water and sediments mainly accumulated a greater abundance of smaller-sized, low-density, and fibrous MPs. MP distribution patterns were similar and mainly affected by population density, flow velocity, and precipitation. The distance-decay relationship of MP communities in surface water was stronger (p < 0.001) compared to sediments and soils. The longitudinal connectivity of the river, input of pollution sources and tributaries also facilitated transport of MP particles. Meanwhile, the retention of MPs in sediment was significantly influenced by MP characteristics and sediment grain size; and higher observed diversity (1.82) and abundance of MPs (130.32 items/kg) deposited in sediment also suggested continuous accumulation. The transport of MPs in riparian soils revealed a preference via vertical pathways and to adjacent sites. Considering limited transport capacity and significant correlations between topsoil and water/sediment, riparian soil may act as a potential long-term sink for river MPs. Our case-specific results are analyzed within a wider framework to further understand fate and transport dynamics of MPs within global riverine ecosystems.
淡水环境中的微塑料污染作为一种新兴污染物,因其对人类健康和环境健康的潜在危害而受到越来越多的关注。然而,目前对河流生态系统区间多聚体多样性的变异性和分布格局的认识仍然有限,也缺乏实地资料。这阻碍了对淡水环境中命运和迁移机制的理解和基于科学的信息。因此,我们的研究重点是报告河流生态系统区室中MP多样性和分布模式的变异性。通过群落分析,我们发现不同生态区间的群落特征和分布差异显著。此外,不同区室的MP群落结构特征不同,但并非完全隔离,反映了分散和生态位分化(环境过滤)之间的平衡。具体来说,地表水和沉积物主要积聚了大量的小尺寸、低密度和纤维状MPs。MP分布格局相似,主要受种群密度、流速和降水量的影响。与沉积物和土壤相比,地表水中MP群落的距离衰减关系更强(p < 0.001)。河流的纵向连通性、污染源和支流的输入也促进了颗粒物的运输。同时,MPs在沉积物中的滞留量受MPs特性和沉积物粒度的显著影响;沉积物中MPs的多样性(1.82项/kg)和丰度(130.32项/kg)均为连续积累。MPs在河岸土壤中的运输显示出通过垂直途径和邻近地点的偏好。考虑到有限的运输能力和表土与水/沉积物之间的显著相关性,河岸土壤可能作为河流MPs的潜在长期汇。我们在更广泛的框架内分析了具体案例的结果,以进一步了解全球河流生态系统中MPs的命运和运输动态。

The understanding of organophosphate ester (OPE) trophic transfer in terrestrial food chains remains limited. In present study, sixteen tri-OPEs and ten di-OPEs in soil, plant, plateau pika, and eagle samples from the Tibetan Plateau were collected and analyzed to investigate the trophic transfer of OPEs in terrestrial ecosystem. Mean ∑ di-OPEs in soil (2.3 ng/g dw), plants (5.7 ng/g dw), plateau pikas (7.4 ng/g dw) and eagles (7.8 ng/g dw) were comparable to those ∑ tri-OPEs in corresponding samples (2.0, 5.6, 8.7 and 4.6, respectively). The trophic magnification factors (TMFs) of tri-OPEs (0.05–0.7) and di-OPEs (0.3–0.8) indicated their low biomagnification potential in the terrestrial food chain. Positive correlations (p = 0.004–0.06) between the logarithmic transformed molar ratio of alkyl di-OPE to tri-OPE and trophic levels, indicated an enhancing metabolic transformation of OPEs at higher trophic levels, thus resulting in trophic dilution. Metabolic transformation of OPEs demonstrates distinct structural specificity, as evidenced by the significantly higher log (ndi-OPEs/ntri-OPEs) ratio for alkyl OPEs (mean = 0.5) than chlorinated OPEs (mean = 0.2; p = 0.005) and aryl OPEs (mean = 0.08; p < 0.005). The present study highlighted the significance of metabolism to OPEs trophic transfer potential along terrestrial food chain.
对陆生食物链中有机磷酯(OPE)营养转移的认识仍然有限。本研究收集了青藏高原土壤、植物、高原鼠兔和飞禽中16种三OPEs和10种二OPEs,探讨了陆地生态系统中OPEs的营养转移。土壤(2.3 ng/g dw)、植物(5.7 ng/g dw)、高原鼠兔(7.4 ng/g dw)和鹰(7.8 ng/g dw)的平均∑2 - opes与相应样品(2.0、5.6、8.7和4.6)的∑3 - opes相当。三opes(0.05 ~ 0.7)和二opes(0.3 ~ 0.8)的营养放大因子(TMFs)表明它们在陆地食物链中的生物放大潜力较低。烷基二- ope与三- ope的对数转化摩尔比与营养水平呈正相关(p = 0.004-0.06),表明高营养水平的OPEs代谢转化增强,从而导致营养稀释。OPEs的代谢转化表现出明显的结构特异性,烷基OPEs的log (ndi-OPEs/ntri-OPEs)比值(平均值= 0.5)明显高于氯化OPEs(平均值= 0.2;p = 0.005)和芳基OPEs(平均值= 0.08;p < 0.005)。本研究强调了代谢对陆地食物链中OPEs营养转移潜力的重要意义。

Cadmium (Cd) contamination in agroecosystems is a global concern, due to its negative influence on soil health and crop performance. Regenerative strategies have been widely recognised as vital to improve soil quality and crop yields. Yet strategies are needed that also mitigate rather than exacerbate the impacts of Cd contamination. In this context, interactions between regenerative strategies, and edaphic, climatic and topographic factors are poorly understood. This study presents a meta-analysis with effect size statistics, evaluating the interactions between regenerative strategies (biochar, manure and compost), non- regenerative strategies (sewage-sludge and fertilizer), soil properties (pH, SOM and Cd levels), climatic factors (temperature and precipitation), and elevation. In acidic or high SOM soils, fertilizer increased Cd uptake by 50% to 76%. However, biochar or compost addition in these soils reduced Cd uptake. Under high Cd contamination, biochar application increased shoot biomass, but fertilizer application decreased shoot-biomass. The application of fertilizer or sewage-sludge under higher temperatures increased Cd uptake, whereas biochar reduced Cd uptake. At wet sites, fertilizer addition increased soil Cd accumulation. At high elevations, biochar was more effective than manure at reducing Cd accumulation. We conclude that there are complex interactions between regenerative strategies and environmental conditions; determining impacts on soil and crop health. The interactions between environmental factors and use of sewage-sludge or fertilizer could exacerbate soil and plant Cd toxicity. Regenerative strategies, especially biochar, could mitigate Cd toxicity in agroecosystems.
由于镉对土壤健康和作物生产性能的负面影响,农业生态系统中的镉污染是一个全球关注的问题。再生策略已被广泛认为是改善土壤质量和作物产量的关键。然而,需要一些策略来减轻而不是加剧镉污染的影响。在这种情况下,人们对再生策略与地理、气候和地形因素之间的相互作用知之甚少。本研究采用效应量统计进行meta分析,评估再生策略(生物炭、粪肥和堆肥)、非再生策略(污水污泥和肥料)、土壤特性(pH、SOM和Cd水平)、气候因素(温度和降水)和海拔之间的相互作用。在酸性或高SOM土壤中,肥料使镉吸收增加50% ~ 76%。然而,在这些土壤中添加生物炭或堆肥会降低镉的吸收。在高镉污染条件下,施用生物炭提高了地上部生物量,施用化肥降低了地上部生物量。在较高温度下施用化肥或污泥增加了镉的吸收,而生物炭则降低了镉的吸收。在湿地,施肥增加了土壤Cd的积累。在高海拔地区,生物炭比粪肥更有效地减少镉的积累。我们得出结论,再生策略与环境条件之间存在复杂的相互作用;确定对土壤和作物健康的影响。环境因子与污泥或肥料利用之间的相互作用会加剧土壤和植物的镉毒性。再生策略,特别是生物炭,可以减轻农业生态系统中的镉毒性。

Strobilurin fungicides (SFs), a class of novel pesticides extensively applied in agricultural production, have raised growing concerns because of their escalating usage and persistent environmental presence. This study investigated the occurrence, fate, mass balance, and ecological risks of SFs in four wastewater treatment plants (WWTPs) in a megacity in southern China, Guangzhou. Nineteen SFs were detected in the aqueous phase, suspended particulate matter, sludge and surface water. The concentrations of individual SFs in the influent were determined to be 0.04–13.9 ng/L. In the effluent, their concentrations decreased to 0.01–7.68 ng/L. The average removal efficiency for individual SFs varied between −19% and 93% across the WWTPs, indicating that a considerable proportion of these contaminants may not be fully eliminated through the current processing technologies. Analysis of mass balance as well as parent-metabolite pairs in different processing units in the WWTPs indicate the generation of unknown transformation products in the treatment system, suggesting neglected environmental burden of SFs. Mass balance analysis also revealed that the daily mass loads of the individual SFs ranged from 1.04 mg/d to 20,384 mg/d, with per-capita emissions spanning 0.01–8.43 mg/d/1000 persons. Risk assessment showed that the pyraclostrobin, famoxadone, and azoxystrobin in the effluent could pose moderate ecological risks for the aquatic environment. These findings demonstrate that WWTP effluents serve as critical pathways for SFs into aquatic environments, and conventional treatment cannot fully mitigate their ecological risks.
Strobilurin杀菌剂(SFs)是一类广泛应用于农业生产的新型农药,由于其不断增加的使用和持续的环境存在而引起越来越多的关注。本研究调查了中国南方大城市广州4个污水处理厂(WWTPs)中SFs的发生、命运、质量平衡和生态风险。在水相、悬浮颗粒物、污泥和地表水中检测到19种SFs。测定进水中单个SFs的浓度为0.04 ~ 13.9 ng/L。出水浓度降至0.01 ~ 7.68 ng/L。各个污水处理厂对单个SFs的平均去除率在- 19%到93%之间,这表明通过目前的处理技术可能无法完全消除相当大比例的这些污染物。对污水处理厂中不同处理单元的质量平衡和亲本代谢物对的分析表明,在处理系统中产生了未知的转化产物,表明SFs的环境负担被忽视。质量平衡分析还显示,个体sf的日质量负荷范围为1.04 mg/d至20384 mg/d,人均排放量为0.01-8.43 mg/d/1000人。风险评估结果表明,出水中吡咯菌酯、法莫沙酮和偶氮菌酯对水生环境构成中度生态风险。这些研究结果表明,污水处理厂出水是SFs进入水生环境的重要途径,常规处理不能完全减轻其生态风险。
