Abstract
We have investigated the treatment of endocrine disrupting chemicals (EDCs) and halogented organic compounds (HOCs) in wastewater by ionizing radiation in the CRP. Three samples of the actual wastewater having estrogen activity were analyzed by the yeast two-hybrid assay, enzyme linked immunosorbent assay (ELISA) and total organic carbon (TOC) analysis. Treatment of the wastewater is required to decrease the estrogen activity to less than 1 ng / L; the lower limit concentration of appearance of endocrine disrupting property. Medaka estrogen activity (mEA) initially increased and then decreased by β-ray irradiation, indicating that decomposition products in the real wastewaters also have the estrogen activity. The doses required to decrease in mEA of samples 1 to 3 below 1 ng / L, D{sub 1ng}, were estimated to be 100, 200 and 150 Gy (J kg{sup -1}), respectively. Since the D{sub 1ng} of 17 β-stradiol (E2) at 500 ng/L (1.8 nmol/L) in pure water was estimated to be 5 Gy as mentioned in the previous CRP, the elimination of estrogen activity of real wastewater is considered to be interfered by organic impurities. The economic cost of the treatment process of EDCs using electron beam was estimated at 17 yen m{sup -3}. (author)
