This course explores the biogeochemical behavior of trace elements, focusing on processes driving their cycling in aquatic and terrestrial systems. It examines how abiotic and biotic transformations interact to shape trace element dynamics, with examples from both natural and engineered environments.

The course offers a practical introduction into the investigation of the biogeochemistry of trace elements. Laboratory experiments are performed to study a selected environmental process. Advanced techniques for the analysis of total element contents and element speciation are used. The experimental findings are interpreted and discussed in their environmental context.

First, the students learn how to analyze soil systems with physical, chemical and microbiological methods. Later, the students train their experimental skills by conducting kinetic experiments in the laboratory and by quantifying process rates under field conditions in a river.
