My research has been focused before all on various environmental gechemical problems. My research begun with geochemistry of waters with respect to toxic metals such as Be, Al and Pb. Envrionmetal theme I came across has been the acidification, its effects on environment and connected problems - the Czech Republic belongs to the areas with the greatest damage to the environment by this phenomenon. Recent topics of my research are dynamics of mercury (Hg) in the environment, geochemical research of the dust materials and redox processes in forest soils.
