Decomposition of ${it p}$-nonylphenols in water and elimination of their estrogen activities by $$^{60}$$Co $$gamma$$-ray irradiation

Decomposition of ${it p}$-Nonylphenols (NPs) in water at 1 $$mu$$mol dm$$^{-3}$$ was decreased exponentially with absorbed dose when NPs were irradiated by $$^{60}$$Co$$gamma$$-rays. Two products having molecular weight of 236, presumably OH adducts of NPs, were detected by LC-MS analyses. The elimination of estrogen activity of aqueous NPs solution including such irradiation products at 5000 Gy (J kg$$^{-1}$$) was confirmed by the yeast two hybrid assay. These results should expand the application of ionizing radiation to the treatment of NPs.
