Pesticides as one of the micro-pollutants present a great problem and threat to the environment and human health. They can infiltrate the sources of drinking water by application on the agricultural fields. This article is focused on Atrazine, Terbuthylazine and their metabolites. It is their complex structure that makes them hard to degrade naturally and, thus, water needs to be treated before safe using. Therefore, this article studies adsorption on the two granular activated carbons Filtrasorb 400 and Norit 1240 W. For the determination of the concentration liquid chromatography was used. In this article it is presented that Filtrasorb 400 efficiency (26–40% and 33–45% for atrazine and terbuthylazine respectively) is better than the efficiency of Norit 1240 W (9–27% and 10–24% for atrazine and terbuthylazine respectively).

In analysis of drinking water frequently ‘new’ elements are occurring, causing a change in water quality. Among these elements bromates are included. Bromates (BrO3-) are toxic substance that is not commonly determination in drinking water. They are usually formed as byproducts of water disinfection by ozone in the present of bromine ions (BrO-) in treated water. In some cases, they can be in natural form, for instance in the water source Dvorníky in Slovak Republic. As stated by Environmental Protection Agency bromates are classified as a dangerous substance that can cause health problems and therefore they must be removed from the water.
