Implications of Downstream Nitrate Dosage in anaerobic sewers to control sulfide and methane emissions
Nitrate (NO3-) is commonly dosed in sewer systems to reduce sulfide (H2S) and methane (CH4) produced in anaerobic rising main pipes. However, anoxic conditions along the whole rising pipes are difficult and costly to ...
Ecotoxicological risk assessment of chemical pollution in four Iberian river basins and its relationship with the aquatic macroinvertebrate community status
Ecotoxicological risk assessment of chemical pollution in four Iberian river basins (Llobregat, Ebro, Júcar and Guadalquivir) was performed. The data set included more than 200 emerging and priority compounds measured at ...
Pollution-induced community tolerance to non-steroidal anti-inflammatory drugs (NSAIDs) in fluvial biofilm communities affected by WWTP effluents
We assessed the tolerance acquired by stream biofilms to two non-steroidal anti-inflammatory-drugs (NSAIDs), ibuprofen and diclofenac. Biofilms came from a stream system receiving the effluent of a wastewater treatment ...
Pharmaceuticals and pesticides in reclaimed water: Efficiency assessment of a microfiltration–reverse osmosis (MF–RO) pilot plant
Water reuse is becoming a common practice in several areas in the world, particularly in those impacted by water scarcity driven by climate change and/or by rising human demand. Since conventional wastewater treatment ...
Faecal microbiota and antibiotic resistance genes in migratory waterbirds with contrasting habitat use
Migratory birds may have a vital role in the spread of antimicrobial resistance across habitats and regions, but empirical data remain scarce. We investigated differences in the gut microbiome composition and the abundance ...
Early-Career Coordinated Distributed Experiments: Empowerment Through Collaboration
Coordinated distributed experiments (CDEs) enable the study of large-scale ecological patterns in geographically dispersed areas, while simultaneously providing broad academic and personal benefits for the participants. ...
Effects of multiple stressors on river biofilms depend on the time scale
Global change exposes ecosystems to a myriad of stressors differing in their spatial (i.e. surface of stressed area) and temporal (i.e. exposure time) components. Among freshwater ecosystems, rivers and streams are subject ...
Protecting and restoring Europe's waters: An analysis of the future development needs of the Water Framework Directive
The Water Framework Directive (WFD) is a pioneering piece of legislation that aims to protect and enhance aquatic ecosystems and promote sustainable water use across Europe. There is growing concern that the objective of ...
Nutrients versus emerging contaminants-Or a dynamic match between subsidy and stress effects on stream biofilms
Freshwater ecosystems are threatened by multiple anthropogenic stressors, which might be differentiated into two types: those that reduce biological activity at all concentrations (toxic contaminants), and those that ...
Integrating ecosystem services in river basin management plans
British Ecological SocietyAccording to the European Union Water Framework Directive, river basin management plans must include a programme of measures, with a series of management actions aiming to achieve good ecosystem ...
Exploring the contribution of bacteriophages to antibiotic resistance
Bacteriophages (phages) are the most abundant and diverse biological entities in our planet. They infect susceptible bacterial hosts into which they either multiply or persist. In the latter case, phages can confer new ...
Biochemical quality of basal resources in a forested stream: effects of nutrient enrichment
We studied biochemical changes in biofilm and suspended particulate and dissolved organic matter (OM) during the leaf emergence period (March–May 2008) in a forested headwater stream in response to a long-term (4 years, ...
Identifying regions vulnerable to habitat degradation under future irrigation scenarios
The loss and degradation of natural habitats is a primary cause of biodiversity decline. The increasing impacts of climate and land use change affect water availability, ultimately decreasing agricultural production. Areas ...
Diversity of Miscellaneous Crenarchaeotic Group archaea in freshwater karstic lakes and their segregation between planktonic and sediment habitats
The Miscellaneous Crenarchaeotic Group (MCG) is an archaeal lineage whose members are widespread and abundant in marine sediments. MCG archaea have also been consistently found in stratified euxinic lakes. In this work, ...
Shared effects of organic microcontaminants and environmental stressors on biofilms and invertebrates in impaired rivers
Land use type, physical and chemical stressors, and organic microcontaminants were investigated for their effects on the biological communities (biofilms and invertebrates) in several Mediterranean rivers. The diversity ...
Flow regulation by dams affects ecosystem metabolism in Mediterranean rivers
Large dams regulate river hydrology and influence water chemistry, sediment dynamics, channel form and biotic communities. These effects may translate into important changes in river ecosystem processes, especially in ...
Assessment of the water supply: demand ratios in a Mediterranean basin under different global change scenarios and mitigation alternatives
Spatial differences in the supply and demand of ecosystem services such as water provisioning often imply that the demand for ecosystem services cannot be fulfilled at the local scale, but it can be fulfilled at larger ...
Hot spots for carbon emissions from Mediterranean fluvial networks during summer drought
During summer drought, Mediterranean fluvial networks are transformed into highly heterogeneous landscapes characterized by different environments (i.e., running and impounded waters, isolated river pools and dry beds). ...
Environmental contaminants of emerging concern in seafood - European database on contaminant levels
Marine pollution gives rise to concern not only about the environment itself but also about the impact on food safety and consequently on public health. European authorities and consumers have therefore become increasingly ...
Solar Light Activation of Persulfate by TiO2 / Fe2O3 Layered Composite Films for Degradation of Amoxicillin: Degradation Mechanism, Matrix Effects, and Toxicity Assessments
In this study, sandwich-type composites made of commercial TiO2-P25 and α-Fe2O3 are obtained by spin coating thin films with different layer configurations, namely: i) TiO2 layer over α-Fe2O3 (TiO2@α-Fe2O3), ii) α-Fe2O3 ...
