| Outline of Final Research Achievements |
During the period, the researchers conducted a series of studies on colorimetrical technology for determining unexpected, potential risk factors of man-made chemicals in reclaimed water. First, divalent cations in reclaimed water were colorimetrically examined with cation-sensitive artificial luciferases (ALucs), which was originally developed the researchers. Further, we determined (i) the male and female sex hormone-like activities and the antagonistic effects, and (ii) teratogenicity of man-made chemicals in reclaimed water. The study revealed that some chemicals have a synergetic effect by combining with other chemicals, although they are poor in the antagonistic activity to female sex hormones. A new luminescent probe was also developed for determining immunotoxicity of chemicals in reclaimed water. We published 8 science journals and conducted 6 presentations in academic society meetings.
