The findings of a new measurement campaign on Lake Kivu in Africa show that, contrary to previous assumptions, the methane concentration in the water is relatively stable or increasing only very slowly. Therefore, the risk of a sudden gas eruption from the lake is currently not increasing.

Exploration and utilisation of resources from the world’s oceans is not equally distributed across the globe. Although many of these resources originate in the Global South, they are mostly being researched by just a few countries from the North. Accordingly, this is also where most of the benefits and profits are flowing to, despite the Convention on Biological Diversity. This was the finding of an analysis of literature from the last 50 years.

Whether a lake was once polluted with excess nutrients is reflected even decades later in the community of bacteria living on these nutrients in the sediment. However, there is still surprisingly little research into how microbes in the sediment cooperate.

There are solid psychological explanations for how consistently we follow the behaviour rules to prevent the spread of Coronavirus, such as the expectations we have towards ourselves and others. These are the findings of a representative survey, the results of which can now be used to optimise public information campaigns.

Circular economy also holds great potential when it comes to wastewater. At NEST, Eawag is conducting research on decentralized wastewater treatment with the aim to use wastewater as a source of nutrients, energy and water. Important partners are Keramik Laufen AG with the urine separation toilet "Save!" and the Eawag Spin-off Vuna with the liquid fertilizer made of urine "Aurin".

Air quality in Switzerland has improved but is still not good enough. To continue the monitoring of air pollutants which has taken place for many years in Dübendorf (ZH), today  federal government has opened a new station as part of its National Air Pollution Monitoring Network (NABEL) on the Empa-Eawag-campus.

Adaptation to warmer environmental conditions may increase the resistance of viruses, making them harder to be inactivated. This is the finding of a new study involving Eawag. Global warming could therefore make it more difficult to combat viruses.

Until recently, researchers assumed that Switzerland had around 20 native species of amphipods. Now, a project by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the University of Zurich has revealed that there are actually more than 40. It is always worth taking a closer look, because we can only protect the things that we know exist.

Process Engineer Adriano Joss from Eawag water research institute has been working for many years on wastewater treatment plants and the removal of micropollutants from water. Together with Ralf Kägi, Head of the Eawag Particle Laboratory, he has compiled the current status of knowledge on microplastics. In an interview, he presents the most important findings. We have recently posted detailed information on the website “Microplastics in the environment”.

Researchers from Agroscope, Eawag, University of Bern and ETH have developed a method for the comprehensive detection of organic pollutant residues in soils and sediments. Initial results show that, in addition to known substances, there are also a number of substances detected for the first time.

Using genomic analyses of 100 cichlid species, scientists from Eawag and the University Bern, together with co-workers in Australia, the UK, Tanzania, Uganda and the US, have investigated the striking variation observed in cichlid fish speciation rates. Their findings show that exchanges of genetic variants between existing species dramatically accelerate the development of new species – given favourable ecological conditions.

Blue-green algae are very common both in the water and on land. Sporadically, they occur in lakes on the surface in such large numbers that one speaks of a bloom. Because there are species that can produce toxic substances, many questions arise.

The Swiss National COVID-19 Science Task Force has been mandated by various federal agencies to act as a national scientific advisory body in the context of the COVID-19 pandemic. The current deputy head Martin Ackermann, head of Eawag’s Environmental Microbiology Division and ETH Professor of Ecology of Microbial Systems, will take over as head of the task force from 1 August 2020.

In addition to ozonation, filters using granulated activated carbon (GAC) are increasingly being deployed to eliminate trace substances from municipal wastewater. Working in conjunction with authorities and representatives from the field, Eawag has developed a document that will assist stakeholders with planning in relation to such measures.

Biodiversity and thus the state of river ecosystems can now be predicted. To achieve this, researchers from the University of Zurich and Eawag (Aquatic Science and Technology) are combining environmental DNA with hydrological methods. Using the river Thur as an example, the approach allows identifying target areas for conservation and initiating protective measures.

Four young researchers from the department SWW received an “Early Postdoc.Mobility fellowship” from the SNSF to broaden their scientific profile abroad: Mariane Schneider, Lena Mutzner, Omar Wani and Matthews Moy de Vitry. The four have already worked together as a team during their doctorate and have published, among other things, a review for the future of water management.

The Verband zum Schutz des Greifensees (VGS) (Association for the Preservation of Lake Greifensee) elected its new Council of Delegates on 25 June 2020. In addition to representatives of all municipalities surrounding the lake, the committee also includes cantonal agencies, farmers, fishermen, sailors and – for the first time – a research representative, with the election of Eawag’s Piet Spaak as an aquatic ecologist.

Natural environments vary in space and time and are now drastically changing due to human activities. Environmental changes, like increasing acidity in a pond, can strongly affect the long-term prospects of species. Katja Räsänen from Eawag’s department Aquatic Ecology aims to understand how natural populations of the moor frog adapt to environmental change.
