These studies are conducted outside the country (currently Siberia and Central Asia), therefore their implementation is related to the organization of scientific expeditions to the studied regions. The main research concerns the quality of water, which is indirectly related to the condition of the soil and the conditions of the local flora and fauna. Moreover, the performance of rainwater analyzes is a source of knowledge about air quality. The basis for conducting research in these regions is the long-term cooperation with the University of Tomsk (Western Siberia). The results of the expeditions and research conducted include numerous articles in foreign journals, and above all, book publications (Western Siberia, Wetland). More on scientific expeditions will be available soon on the blog.
