Abstract

The behavior of estrogens (estrone: E1, 17beta-estradiol: E2, estriol: E3 and ethinylestradiol: EE2) and an androgen (testosterone) in the water and sludge from Johkasou in Japan was investigated. The concentrations of E1, E2, E3 and testosterone in water samples from the Johkasou were 33-500, N.D. approximately 150, N.D. approximately 6,700 and 500 ng/L, respectively. In sludge samples, the concentrations of E1, E2, E3, and testostrerone were N.D. approximately 39, N.D. approximately 6.7, N.D. approximately 60 and 0.2-9.0 ng/L, respectively. EE2 was not detected in all samples. The removal rates of E1, E2, E3 and testosterone in Johkasou were 45%-91%, 66%-100%, 90%-100%, and about 90%, respectively.
