José Gregorio Cuevas,Ángel Faz,Silvia Martínez-Martínez et al.
José Gregorio Cuevas et al.
Cartagena-La Union mining district (SE Spain) has unconnected dry riverbeds, which transport mining waste downstream under torrential rain events, polluting a coastal lagoon (Mar Menor). Additionally, in the cropland Campo de Cartagena, agr...
Distribution and effects of microplastics as carriers of heavy metals in river surface sediments [0.03%]
河流表层沉积物中微塑料作为重金属载体的分布和效应
Changyuan Wang,Xin Liu,Qianqian Ma et al.
Changyuan Wang et al.
There are few studies on microplastics (MPs) in urban river sediments compared to oceans, soils, and even rivers. In this study, the seasonal abundance of MPs, as well as their influencing factors on heavy metal adsorption in river sediment...
Effects of antibiotic resistance genes on health risks of rivers in habitat of wild animals under human disturbance - based on analysis of antibiotic resistance genes and virulence factors in microbes of river sediments [0.03%]
抗生素抗性基因对人类干扰下野生动物栖息地河流健康风险的影响——基于河床沉积物微生物的抗生素抗性基因和毒力因子分析
Rongpan Hu,Minxing Ren,Sumei Liang et al.
Rongpan Hu et al.
Studying the ecological risk of antibiotic resistance genes (ARGs) to wild animals from human disturbance (HD) is an important aspect of "One Health". The highest risk level of ARGs is reflected in pathogenic antibiotic-resistant bacteria (...
The competition of heavy metals between hyporheic sediments and microplastics of driving factors in the Beiluo River Basin [0.03%]
贝洛河河水渗滤带中微塑料和底泥重金属竞争机制及驱动因素研究
Bingjie Li,Ruichen Mao,Zeyu Chen et al.
Bingjie Li et al.
Both sediments and microplastics (MPs) are medias of heavy metals (HMs) in river ecosystems. This study investigated HMs (Mn, Cr, V, As, Cu, Co, Cd, Pb, and Ni) concentration and driving factors for competitive enrichment between hyporheic ...
Hidden delta degradation due to fluvial sediment decline and intensified marine storms [0.03%]
河流输沙量减少和海洋风暴加剧导致的隐性三角洲退化
Qingguang Zhu,Fei Xing,Ya Ping Wang et al.
Qingguang Zhu et al.
Deltas are threatened by erosion due to climate change and reduced sediment supply, but their response to these changes remains poorly quantified. We investigate the abandoned Yellow River delta that has transitioned from rapid growth to on...
Geochemistry and origin of inorganic contaminants in soil, river sediment and surface water in a heavily urbanized river basin [0.03%]
地质化学和重污染河流盆地土壤、河床沉积物及地表水中无机污染物来源研究

Zacharenia Kypritidou et al.
Understanding the geochemistry and contamination of rivers affected by anthropogenic activities is paramount to water resources management. The Asopos river basin in central Greece is facing environmental quality deterioration threats due t...
Impact of Anthropogenic Activities on Microbial Community Structure in Riverbed Sediments of East Kazakhstan [0.03%]
人为活动对哈萨克斯坦东部河床沉积物中微生物群落结构的影响
Olga Muter,Dita Gudrā,Gulzhan Daumova et al.
Olga Muter et al.
Heavy metal (HMe) pollution in regions with mining and metallurgy activities is known to be a serious environmental problem worldwide. Hydrological processes contribute to the dissemination of HMes (drainage, precipitation, flow rate). The ...
Distribution and ecological risk assessment of priority water pollutants in surface river sediments with emphasis on industrially affected areas [0.03%]
优先控制水污染物在表层河床沉积物中的分布及生态风险评估——以工业影响区域为重点
