Radiation Treatment for Endocrine Disrupters in Water

摘要

The radiation-induced decomposition of a trace amount of 17 β-estradiol (E2) in water was studied as a function of the dose of 60Co γ-rays. Concentration of both E2 and E2 activity were estimated by LC-MS and ELISA, and decreased with an increase in the dose of γ-rays. E2 at 1.8-nM in water was degraded almost completely by irradiation at 10 Gy (= J/kg), but the E2 activity of the same sample still remained, and decreased by 30 Gy to be lower than the threshold level of contamination to induce some estrogenic effects on the environmental ecology.
