Opis (eng)

Pharmaceuticals are a group of emerging substances which are present in the environment and appear to be relatively constant at low concentrations. With the development of modern analyical methods more pharmaceuticals can be detected in the water sphere of the environment. Study of the behavior and transport of pharmaceuticals in groundwater is significant for understanding the processes of natural attenuation and potential use of filtration through the aquifer to evaluate the most effective way to remove micropollutants that occur under anthropogenic influence. Due to insuffrcient quantities of data on the characteristics of the subsurface structure and mechanism and behavior of the studied pharmaceuticals during groundwater transport, tracer experiments can be a very effective method for the characterization and examination ofpharmaceutical behavior in relation to transportation of non-reactive tracer. The implementation of tracer experiment, provide data on effective parameters and data about breakthrough curves of pharmaceuticals in relation to the breakthrough curve of non-reactive tracer, on which basis parameters of transport can be determined and used for further modeling and forecasting. Removal of pharmaceuticals occurs mainly due to biological degradation of micropollutants, while on the other hand sorption retards the transport. Quantifying the effects of biodegradation and sorption during a field tracer experiment was insuffrciently studied, and therefore the implementation of tracer experiment represents very useful method to obtaining better and more precise data. This paper represents the results of field research on the location of the drainage system Kovin Dubovac, during which tracer tests experiment was conducted and behavior of selected pharmaceuticals was monitored (Trimethoprim, Carbamazepine, Diclofenac and metamizole metabolites 4-AAA and 4-FAA). Aim of this paperwork is to show and analyze the results of tracer experiment during which the tracer NaCl was discharged, and to correlate the obtained data on the characteristics of the subsurface, as well as the results of the breakthrough curve of selected pharmaceuticals so the effects of sorption and biodegradation can be quantified.
