Perović, Marija
The aim of the dissertation research is to determine concentration levels, relationships, conditionаlities and correlations between compounds involved in nitrogen transformations in selected surface and groundwaters. Changes in the concentration levels of physicochemical parameters which indicate the fulfillment of conditions for certain transformation processes, the origin of groundwater and anthropogenic impacts on water quality were all analysed. Groundwater potential for nitrogen conservation was determined. Detailed hydrogeochemical, microbiological, isotopic and statistical analysis were conducted for two aquifers under agricultural areas, representing different effects of the oxicity conditions on the nitrogen transformation and transport, the regional groundwater source Ključ and drainage system Kovin-Dubovac. The results of the laboratory and field experiments were used to identify the pathways and model the kinetics of nitrate reduction.
