April 4, 2018Monitoring the effects of chemicals on environmental systems with many species has always been a challenge. On behalf of the Federal Office for the Environment (FOEN), Eawag and the Ecotox Centre-EPFL investigated how the regulation of genes in fish and in single fish cells allow scientists to deduce water quality and fish health.

March 27, 2018Rubber ducks and crocodiles have always been popular bathtime companions. An Eawag study has now revealed the “dark side” of flexible plastic bath toys. Diverse microbial growth is promoted not only by the plastic materials but by bath users themselves.

March 19, 2018“A rolling stone gathers no moss.” This is the saying credited with giving the famous British rock band its name…but does it hold true from an ecological or hydraulic engineering perspective? 

March 13, 2018The Geochemical Society and the European Association of Geochemistry (EAG) have awarded Janet Hering, Director of Eawag and Professor in Environmental Biogeochemistry at ETH Zurich and Environmental Chemistry at EPFL, the title of Geochemical Fellow.

March 8, 2018Eawag scientist Lenny Winkel was appointed as Associate Professor of Environmental Inorganic Geochemistry by the ETH board. Lenny Winkel leads the group Environmental Inorganic Geochemistry within the Department Water Resources and Drinking Water and is until today Assistant Professor at ETH Zurich.

March 7, 2018In 2017, 68 cities (mostly in Europe) again took part in a large-scale project measuring drug levels in wastewater. The results for 2017 were published today by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). 

March 5, 2018River networks are dendritic and have a physical direction. The influence of these spatial preconditions on the dispersal of species and the dynamics within metacommunities has been the focus of research for a number of years. 

February 22, 2018The earth’s water supply is changing because of global warming: the ratio of precipitation to evaporation is sinking, and additional arid zones may emerge. The speed at which this development is likely to take place has been analysed by an international team including Eawag researchers. 

February 19, 2018If the climate heats up, the temperature in the uppermost layer of lakes will increase, the thermic layering will become more stable and last longer, and less oxygen will reach the depths – this is the present theory on the effect of climate change on lakes.

February 15, 2018A shower hose will often contain more bacteria than the rest of the building’s plumbing system. A research team led by Frederik Hammes has been investigating this topic for the past four years. In their latest study, they analysed biofilms in 78 shower hoses from 11 countries, and in 21 of them, they detected legionella – a potential pathogen. In this interview, Hammes explains why we should not be unduly concerned.
