Laboratory of Environmental Chemistry

The Laboratory of Environmental Chemistry (LUC) focuses on fundamental research and education for assessing the impact of human activities and natural processes on human health, environment and climate.
The surface chemistry research group investigates multi-phase chemical processes relevant for atmospheric chemistry and the analytical chemistry research group reconstructs environmental and climatic conditions from high-altitude glaciers.

Congratulations to Ling Fang

On 2 June 2020 Ling successfully defended her PhD entitled “Radiocarbon analysis of dissolved organic carbon from ice cores" at the University of Bern. This was the first time that a student from our lab defended online and Ling delivered a great performance. Congratulations! The project was conducted in collaboration with the Laboratory for the Analysis of Radiocarbon with AMS (LARA) of the University of Bern, Nanjing University, and the University of Maine, amongst others, and funded jointly by the University of Bern and the Paul Scherrer Institute.

"We were shocked how far advanced the melting is already"

Energy and Environment

An international expedition with the participation of the Paul Scherrer Institute PSI discovers advanced glacial melting at an elevation of more than 4,000 metres on the Grand Combin in Valais. In the Alps, it may almost be too late for the Ice Memory project, which aims to save ice cores as a climate archive for future generations of researchers.
