Abstract
Estrogen Photodegradation Depends on Solvent and Photolysis Wavelength
Cory Black, Ceilidh Ahearn, Lars (Alex) Olivan, Alexandra Nuñez, and Patrick M. Hare
Hormones pose a threat to wildlife when they enter the water supply. Estrogens in particular have been shown to cause adverse effects at low concentrations. There is much variation in reported products, rates, and which wavelengths are most effective in photolysis of the estrogens. Here, estrone and 17β-estradiol were photolyzed in various solvents and with several wavelengths, and analysis was performed using gas chromatography-mass spectrometry. Appreciable degradation was observed for both molecules. A dominant photoproduct was observed for estrone, which was produced faster in hydrogen-bond-donating solvents and with lower wavelengths. These results may be helpful for waste water remediation.
