March 4, 2019A new study by an interdisciplinary team from Eawag has shown that substances from agriculture affect living organisms in rivers and streams to a greater extent than treated wastewater, which has less impact on the species composition of microorganisms. 

February 28, 2019Aquatic organisms are adapted to harsh conditions at high altitudes and are tolerant of a certain level of disturbances. However, according to a study conducted in the canton of Valais, frequent flushing of water intakes leads to a dramatic decline in populations of macroinvertebrates, such as insects or worms.

February 26, 2019When ecosystems tip abruptly out of balance, this can be catastrophic for humans and for biodiversity. Astonishingly little is known about the role of evolution in such processes. A research team including Eawag scientists has now published approaches to investigating such complex questions in the journal “Nature Ecology & Evolution”.

February 20, 2019As of this week, “LéXPLORE”, a 100 metre research platform, is afloat on Lake Geneva. On board are countless radiosondes and sensors which should enable researchers at Eawag, EPFL and the Universities of Lausanne and Geneva to gain a better understanding of the ecological processes at work in Lake Geneva as well as the interactions between the water and the atmosphere.

February 19, 2019The larvae of black soldier flies feed on organic waste matter. This has the potential not only to alleviate the waste problem in many countries, but also cut greenhouse gas emissions from waste disposal by around half.

February 14, 2019A study by environmental social scientist Mario Angst shows that reports in the media do not always reflect the issues that most concern organisations, public sector agencies, cantons and communities on a day-to-day basis. 

February 11, 2019Selenium is a difficult mineral to research, as it has a complex chemistry and is only found in the environment in the tiniest amounts. However, scientists at Eawag and ETH Zurich have now developed new methods of chemical analysis that, when combined with atmospheric models, allow assumptions to be made for the first time on the origins of selenium.

February 8, 2019In the coming decades, many rivers in Switzerland are to be restored to a natural state. To identify those river reaches where restoration would be ecologically most valuable, Eawag scientists have developed a new assessment procedure.

February 4, 2019More than 98% of the smallest plastic particles from sewers are retained in sludge. Researchers have been able to prove this by incorporating the precious metal palladium as a tracer in artificial nanoplastics. This innovative method has great potential for keeping track of the behaviour of nanoplastics in technical systems as well as in environmental situations.

January 31, 2019In collaboration with Nagra and Bern University, Eawag scientists have studied the gas dynamics in an experimental tunnel simulating the disposal of radioactive waste. While some of the findings are surprising, the overall safety assessment is positive.
