March 9, 2017The water footprint indicates how much water is used to produce consumer goods. A study by Eawag scientists shows that there is a need for standardization in assessments of the grey water component. Comparability is impaired, for example, by the use of different water quality standards. 

February 21, 2017As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the global distribution of selenium.

February 16, 2017Humans influence evolution. In the case of whitefish in Swiss lakes, one consequence of this is replacement of a diversity of specialised species by fewer generalists. A recent analysis now suggests that communities of diverse specialists utilise trophic resources more efficiently.

November 14, 2016The “Regional Water Supply for Basel-Landschaft 21” project, which was started in 2013, culminated today in a media conference in Liestal.

September 29, 2016A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans.

September 16, 2016Switzerland’s lakes are not only diverse ecosystems, but also recreation sites, fishing grounds and energy sources. At this year’s Info Day, the tensions between these competing interests were explored. It was concluded that sustainable management calls for an understanding of the complex interactions occurring in lakes – which in turn requires scientific data and appropriate methods of observation.

August 17, 2016Political actors tend to perceive their opponents as more influential than they really are, and to overestimate the differences between opposing groups. As a result, policy‑making and the search for feasible compromises become more difficult. This phenomenon, as Eawag political scientists have now shown, is apparent even in a consensus-based democracy like Switzerland.

July 12, 2016The new laboratory and experiments building the “Aquatikum” on the grounds of Eawag, the Swiss Federal Institute of Aquatic Science and Technology, in Dübendorf is the first laboratory building in all of Switzerland to receive the Minergie P-Eco Certificate. This commendation honours not only an especially sustainable use of energy, but also the care exercised in choosing building materials and procedures that are both ecologically sound and conforming to health and safety standards.

May 31, 2016In the future, water requirements for global crop production could be reduced as a result of climate change. This is the conclusion of a study by an international research team which included Eawag scientists.

May 20, 2016Ageing infrastructure, global population growth and increasing urbanization call for new approaches in the water supply and wastewater management sector.
