The paper presents the main aspects of the presence of pharmaceuticals in the environment with particular attention to cytostatic drugs (anticancer drugs). The attention has been drawn to the likely ecological threat, source and presence of qualitative and quantitative, and the behavior of cytostatics as well. An attempt was made to assess the ways of their degradation depending on the physicochemical parameters with an overview of the recommended treatment and disposal technologies. High removal states as a result of photooxidation, while the highest efficiency enable electrolytic and chemical reactions. However, to obtaining complete elimination and inactivation enforce the use of hybrid methods.
