• p-nonylphenols
• water
• Co-60 gamma-rays
• LC-MS
• yeast two-hybrid assay

Concentration of p-nonylphenols (NPs) in water at 1 mu mol dm(-3) was decreased exponentially with absorbed dose when NPs were irradiated by Co-60 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.
