August 11, 2022As an additive in toothpaste, it protects our teeth from decay. But when fluoride occurs in nature in larger quantities and accumulates in groundwater, it can become a hazard for our health. For the first time, Eawag scientists have produced a detailed map of global fluoride contamination in groundwater and shown which regions of the world are particularly affected.

July 19, 2022Even though industrial wastewater is treated at state-of-the art plants, the sheer variety of synthetic organic compounds from the chemical and pharmaceutical industry which end up in surface waters are seriously underestimated. This is shown by a new study carried out by Eawag and ETH Zurich.

July 18, 2022A study published today in Nature Microbiology highlights the great advantage of wastewater monitoring as being rapid, unbiased and cost-effective: the detection of genomic variants of SARS-CoV-2 in wastewater offers an early alert and can be based on fewer samples as compared to clinical samples. The bioinformatics tool developed by the groups of Niko Beerenwinkel and Tanja Stadler (ETH, Department of Biosystems Science and Engineering) in collaboration with Eawag and EPFL identifies variants of concern even at low abundance.

July 18, 2022As part of a new national research programme that aims to replace animal experiments in research, the National Science Foundation is supporting a project at Eawag. This opens up new possibilities for determining the toxicity of chemical substances based solely on tests with cultured cells and computer models. Animal experiments could thus be replaced.
