In the frame of sustainable development and environmental protection huge number of important problems emerge in the field of water treatment. Nowadays a very important task is the removal of trace organic pollutants. Some of the trace pollutants cannot be completely removed by the traditional biological treatments and can reach the surface and ground waters. As a consequence, some of these compounds were also found in drinking water, too. In spite of their very low (ng/L) concentration, these trace pollutants can influence the health of several generations. In this group belong some pharmaceuticals, pesticides and the Endocrine Disrupting Chemicals, which can, according to the leading scientists in this field, cause the most of our health problems in the near future. One way to remove the trace pollutants from waters is the application of Advanced Oxidation Processes, based on reactive radical formation. These radicals are capable to transform and/or mineralize the organic pollutants. The main advantage of these methods is that in most cases addition of chemicals into the treated solution is not necessary.

The presentation will focus on Advanced Oxidation Processes, like heterogeneous photocatalysis, UV and VUV photolysis, ozonation and g-radiolysis, trough target molecules from the family of phenyl-urea pesticides and neonicotinoids, as well as non-steroidal anti-inflammatory drugs. The method efficiency will be discussed comparing kinetic parameters, eco-toxicity results using zooplanktons and algae, as well as the calculated Electric Energy per Order values.  

Hungary and the Hungarian Universities will be shortly presented and some details will be given about the University of Szeged and its Institutes.
