Seasonal variation in the xylem sap composition of six Australian trees and shrubs

Alice Jacqueline Frédérique Gauthey

In recent years, xylem sap composition has been shown to affect xylem hydraulics. However, information on how much xylem sap composition can vary across seasons and specifically under drought stress is still limited. We measured xylem sap chemical composit ...

Atmospheric water harvesting in semi-arid regions by membranes: A techno-economic assessment

Kumar Varoon Agrawal, Marina Micari, Xuekui Duan

The availability of a reliable and sufficient amount of water constitutes one of the Sustainable Development Goals set by the United Nations. The provision of water is still challenging in many regions of the world, especially in arid and semi-arid regions ...

Advancements in heavy metals removal from effluents employing nano-adsorbents: Way towards cleaner production

Edgard Gnansounou

Due to the development in science field which gives not only benefit but also introducesundesirable pollution to the environment. This pollution is due to poor discharge activities of industrial effluents into the soil and water bodies, surface run off fro ...

Participatory research to monitor lake water pollution

Luc Patiny

A participatory research team, concerned about water quality around Lake Geneva, particularly in the Montreux Bay region where some were lifeguards, ran sampling campaigns to determine summertime levels of lake water pollution. The participants were brough ...

Adapting the dynamic LakeMab model to simulate seasonal variations of phosphorus concentration in reservoirs: a case study of Lake Bultiere (France)

Camille Roland Marie Minaudo

Controlling phosphorus is fundamental to limit the risk of eutrophication of continental aquatic ecosystems. Integrated modelling of its concentration in the aquatic continuum requires specific tools for water bodies. However, although simple static empiri ...

European demonstration program on the effect-based and chemical identification and monitoring of organic pollutants in European surface waters

Kristin Schirmer, Anita Orsolya Hidasi

Growing concern about the adverse environmental and human health effects of a wide range of micropollutants requires the development of novel tools and approaches to enable holistic monitoring of their occurrence, fate and effects in the aquatic environmen ...

Supported photocatalysts for model pollutant degradation and bacterial inactivation : preparation, evaluation and characterization

Laura Victoria Suárez Murillo

Water quality and bacterial infections are directly related to human health and wellbeing, thus waste water treatment is a necessary procedure for avoiding disturbances to ecosystems and for assuring human health. Furthermore, bacterial contamination in wa ...

New lakes in deglaciating high-mountain regions – opportunities and risks

Anton Schleiss

In connection with the ongoing disappearance of glaciers in cold mountains, a great number of new lakes come into existence. The sites and approximate formation time of such potential new lakes can be realistically modelled. This provides an important know ...

Enhancement of micropollutant degradation at the outlet of small wastewater treatment plants

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Jonas Margot, Pierre Claude Jean Queloz

The aim of this work was to evaluate low-cost and easy-to-operate engineering solutions that can be added as a polishing step to small wastewater treatment plants to reduce the micropollutant load to water bodies. The proposed design combines a sand filter ...

Multiscale modelling of urban climate

Climate has a direct impact on cities' energy flows due to the space conditioning (heating, cooling) needs of the buildings accommodated. This impact may be reinforced due to climate change and to the (so called) urban heat island effect. The corresponding ...

Evaporation from three water bodies of diﬀerent sizes and climates: Measurements and scaling analysis

Marc Parlange, Shirit Cohen, Gabriel George Katul

Evaporation from small reservoirs, wetlands, and lakes continues to be a theoretical and practical problem in surface hydrology and micrometeorology because atmospheric ﬂows above such systems can rarely be approximated as stationary and planar-homogeneous ...

Phosphate adsorption by mineral weathering particles in oligotrophic waters of high particle content

Alfred Johny Wüest, Beat Mueller

We investigated the interactions of dissolved reactive phosphorus (DRP) and dissolved nonreactive phosphorus (DNRP) with suspended and settled aquatic particles. The sorption to minerogenic particles from an alpine catchment collected in rivers, hydropower ...
