Aleksandra KALENIECKA is a Ph.D. student at the Koszalin University of Technology. Her research interest concerns wastewater treatment processes, formation of supramolecular complexes (as guest molecules PAHs and steroids), metabolomic investigation of water ecosystems plants as potential micro indicator organisms as well as biodegradation of endocrine modulators in the presence of macrocyclic compounds. Her research involves analytical protocols using bioreactors, UV-Vis spectrophotometry and chromatography (HPLC, micro-TLC).
