May 21, 2020Many experts describe the health effects of drinking water contaminated with toxic concentrations of arsenic as the greatest mass poisoning in human history. A risk model developed by Eawag researcher Joel Podgorski now shows that up to 220 million people worldwide could be affected.
May 20, 2020To mark this year’s International Day for Biological Diversity on 22 May, professor Catherine Graham and professor Florian Altermatt explain in an interview why it is important in biodiversity research to look beyond systemic boundaries. The two scientists lead the joint research initiative “Blue-Green Biodiversity” between WSL and Eawag.
May 18, 2020To protect ecosystems, it is important to understand how environmental disturbances, such as forest fires or hurricanes, affect nature. A study by Eawag and the University of Zurich now shows how their frequency and intensity affect small and large organisms. Accordingly, large species are more affected by disturbances than small species, and this influences the size distribution within ecological communities.
May 14, 2020In order to increase the permeability of the rock for applications such as the use of geothermal energy, rock is artificially broken. Until now, there was a lack of methods to track this process in the field in real time. Thanks to a new technique, this gap can now be closed, as a study by Eawag and ETH Zurich shows.
May 12, 2020Every year, the Swiss National Science Foundation launches a photography competition to select the best images from the world of science. In the category "The Research Project" the collage of a joint research project of Eawag and the Swiss Tropical and Public Health Institute was recognized.
May 11, 2020How can water supply and wastewater disposal be provided flexibly and efficiently, especially in rapidly growing cities? A new research agenda formulates open questions from a technical, social and transformative perspective. It stresses the importance of transdisciplinary cooperation between research, policy and practice to promote innovation in the water sector.
May 8, 2020In many places in Switzerland, rivers, streams and lakeshores are being restored. The new practice documentation “Evaluating the outcome of restoration projects” by Eawag and FOEN provides the basis for joint learning across project boundaries.
May 7, 2020There is a flip side to the annoying blankets of pollen found on cars, garden furniture and other surfaces: when it comes to satellite images, pollen on lakes reveals currents that are otherwise only visible in computer models. This makes the waterbody researchers and remote sensing experts very happy.
April 30, 2020The novel coronavirus has been successfully detected in wastewater – even at low concentrations, in samples collected at an early stage of the outbreak. Researchers at EPFL and Eawag are now working to optimise the method. The aim is to develop a system which could warn of a resurgence of cases earlier than clinical diagnostic tests.
April 28, 2020The active ingredient diclofenac contained in various painkillers is hardly degraded at all in wastewater treatment plants and therefore accumulates in surface waters. There, amphipods convert diclofenac into a more toxic substance, namely diclofenac methyl ester, as shown in a study by the Swiss Federal Institute of Aquatic Science and Technology (Eawag).
