Research on water quality risk evaluation

In recent years, such water-borne contaminator substances as trace chemical substances and pathogenic microorganisms have been adversely impacting on ecosystems. Even the health and wellbeing of humans and wildlife have been affected. Accordingly, we have been faced with demands for more enhanced understanding of exactly how such trace chemical substances and pathogenic microorganisms pollute aquatic environments. We are also conducting evaluation measures, as well as measures to determine the necessity of carrying out effective countermeasures.

Our research concentrates on developing detection test methods and measures to evaluate the impact of water-borne endocrine disruptors (which have the same properties as female hormones, and are also known "environmental hormones"), dioxins and pathogenic microorganisms. We also seek to clarify the behavior of these substances in the aquatic environment and develop effective sewage treatment methods.
