Abstract: | Background, aim, and scope Many pollutants have received significant attention due to their potential estrogenic effect and are classified as endocrine
disrupting compounds (EDCs). Because of possible ecological effects and increased attention for water reuse schemes, it is
important to increase our understanding of the EDC removal capacities of various wastewater treatment systems. However, there
has so far been little research on the fate and behavior of EDCs in stabilization pond systems for wastewater treatment, which
represent an important class of wastewater treatment systems in developing countries because of their cost-effectiveness.
The aim of this work is to study the fate and behavior of EDCs in algae and duckweed ponds. Because the synthetic hormone
17α-ethinylestradiol (EE2) and the natural hormones estrone (E1), as well as 17β-estradiol (E2), have been detected in effluents
of sewage treatment plants and been suggested as the major compounds responsible for endocrine disruption in domestic sewage;
E1, E2, and EE2 were therefore chosen as target chemicals in this current work. |
