The Black Triangle received extreme sulfur deposition for several decades. By association, Hg deposition was undoubtedly also highly elevated, but research on the distribution, dynamics and fate of Hg in the Czech Republic has been rather scarce. This study will examine the fate of legacy Hg and whether it is still “leaking out” of impacted ecosystems even after emissions have been greatly reduced. We will assess the loading of Hg from upland forests to downstream water bodies, and assess the extent of methylation in the uplands. The combined spatial and temporal records will yield new insights into the behavior and controlling factors of Hg and its toxic forms, like methylmercury, at the fine timescales at which hydrologic and biogeochemical changes occur. This study will also advance our understanding of why organic carbon concentrations and quality vary over time with hydrologic conditions, findings that will be especially relevant to global change scientists.

The Medieval castle Veselí nad Moravou represents a unite European site with many well preserved wooden buildings, construction elements, and unprecedented volume of organic remains. Using the multidisciplinary approach will be clarified the environmental conditions within this locality and the anthropogenical influence on the alluvial plain formation.

The aim of the project is to obtain new answers to frequently formulated questions on the form and demise of Late Neolithic rondels using a special methodology. Micromorphological analysis combined with radiocarbon dating and the classic analysis of archaeological finds will be used to resolve specific questions concerning the existence of Neolithic rondels, especially to clarify the method and time of filling rondel dithech.
