CATalytical and photocatalytical REMoval of Endocrine Disrupting Compounds (EDCs) from waters

A wide variety of chemicals, that are not easily biodegradable and are known to bio-accumulate in water organisms, especially in their fatty tissues, and therefore produce  serious detrimental reproductive effects on wildlife and humans, have been found to be weakly estrogenic [1-4]. Even at low concentrations, steroid estrogens cause the synthesis and secretion of vitellogenin, a female-specific protein, in male fish, resulting in induced sex reversal and/or intersexuality of fish population, and near extinction of fish in the lake [5]. Pesticides, polycyclic aromatic hydrocarbons, phthalate plasticizers, certain polychlorinated biphenyls, dioxins, furans, alkylphenols (APEs), and synthetic steroids belong to the class of endocrine disrupting compounds (EDCs).

The overall objective of the project is to develop a strategy to assess and improve the removal of EDCs in waters using catalytical and photocatalytical oxidation; to investigate an appropriate treatment method that can be integrated into water and wastewater treatment facilities to prevent the release of EDCs into natural waters.
