Abstract
Pyrite and marcasite oxidation in the consequence of lignite surface m ining creates lakes with pH as low as 2 to 3, buffered by high content s of iron and aluminium. Living conditions in this extreme habitat for plants and animals are described as well as the characteristics of th e pioneer settlement. The utilization of these fish-free lakes is very limited. As possibilities for a water quality improvement special rec ultivation methods of overburden, chemical neutralization and biologic al ecotechnologies are recommended.
