This thesis deals with nitrogen ions, i. e. nitrite and ammonia nitrogen in samples of natural waters and the stability of the resulting values. The theoretical part includes list of determination methods of nitrogen in aquatic environment. The practical part contains results of nitrogen ions concentration in chosen water samples and in standards. The aim of this thesis is to evaluate the impact of conservation reagents used to determine nitrogen ions on the final value and changes in these resulting values in a time depending on the analysis. Selected determination of nitrogen ions in natural water samples were performed from June 2014 to April 2015. Consequently the values were graphically processed and evaluated. A conservation reagent affects the resulting values only for the determination of ammonium ions. Stability of measured ion concentration of nitrogen in water samples is at least two hours, even with ammonium nitrate nitrogen it can be extended by conservation cold of samples.
