General description

4-tert-Octylphenol is a potential environmental pollutant and it exhibits toxic and estrogenic effects on mammalian cells. It binds to estrogen receptors and exerts estrogenic actions in vitro. The transformation of the 4-tert-octylphenol upon irradiation at 253.7nm and by hydroxyl radicals generated by the photolysis (λexc = 253.7nm) of hydrogen peroxide in aqueous solution has been studied.
