**Meet the editors**

Prof. Ján Derco, DSc, is a professor of Chemical Engineering at the Institute of Chemical and Environmental Engineering, Faculty of Chemical and Food Technology, Slovak University of Technology (SUT), Bratislava, Slovakia. He graduated in Chemical Engineering from the Slovak University of Technology, Bratislava. Prof. Derco obtained his PhD and DSc degrees from the same

university. He worked at the Department of Environmental Engineering, Faculty of Chemical Technology, SUT, where he also performed most of his research. The main areas of his scientific interest include environmental engineering, biological wastewater treatment, modeling, design and optimization of ozone-based oxidation processes, and investigation of the degradation of hazardous substances.

Branislav Vrana, PhD, is an associate professor and a senior researcher of Environmental Chemistry at the Research Centre for Toxic Compounds in the Environment (RECETOX), Faculty of Science, Masaryk University. He graduated in Chemical Engineering from the Slovak University of Technology, Bratislava, in 1994. Dr. Vrana received his MS degree in Biochemical Technology, in

1998, and his PhD degree in Biotechnology. He has been working internationally at research centers (UFZ Helmholtz Center for Environmental Research, Germany and Water Research Institute, Slovakia) and universities (University of Portsmouth, UK and Masaryk University, Czech Republic) with a focus on the investigation of the fate of environmental pollutants in aquatic environments. Dr. Vrana's main research activities include the development of sampling techniques and analytical methods for assessment of the priority and emerging contaminants in aquatic environments with a special focus on passive sampling techniques.
