A new paper titled “Acid Mine Drainage: The Link Between Melting Permafrost and Heavy Metals in Mountain Lakes” by Philipp Spitzer, Eva Reichmann, and Sebastian Tassoti has been published in the journal CHEMKON. The study explores how melting permafrost and retreating glaciers can lead to increased concentrations of heavy metals in mountain streams and lakes, particularly in regions with sulfide-rich bedrock, such as pyrite.
We present model experiments that demonstrate the low buffering capacity of glacier water and the acidification caused by pyrite oxidation. These experiments, designed for classroom integration, illustrate the release of heavy metals like copper when exposed to acidic conditions. The research also highlights the importance of understanding these environmental processes within the context of climate change.
To enhance accessibility, the experiments are incorporated into the digital learning platform of the project.
