In natural waters with humic acids and dissolved iron, 17α-ethinylestradiol can degrade due to the formation of Fe(III)-HA complexes that facilitate photodegradation through the production of reactive oxygen species, hydrogen peroxide, and Fe(II), and by maintaining higher dissolved iron concentrations and altering the Fe(III)/Fe(II) cycling.
