Abstract: This thesis presents the removal of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in landfill leachate by a tropical constructed wetland (CW) system and the biotransformation of selected perfluoroalkyl acid (PFAA) precursors. The occurrence and distribution of 18 PFASs in the raw leachate and effluents of each treatment unit of the CW system were examined. Lab experiments were conducted to investigate the biotransformation of selected PFAA precursors under various redox conditions by the rhizosphere microbial community from the wetland. The influence of these PFAA precursors on the microbial community structure under aerobic and anaerobic conditions were also examined. In addition, one PFAS-degrading bacterium was isolated from the wetland slurry and characterized. The information obtained sheds light on the sustainable management of PFASs contaminated water and improves the understanding of PFASs biodegradability and their interaction with microbial communities.
