  • Material Cycling in the Environment

Whereas a number of chemical substances are used in our lives to enjoy their benefits we must not overlook their adverse effects on humans and wildlife It is important for us to consider the management of chemical substances through materials processing, use and disposal. The major topic of this program is to clarify the adverse effects of chemical substances such as endocrine disrupting chemicals, pharmaceuticals, pesticides, food additives, soaps/detergents, antimicrobial agents, cosmetics, sunscreens, nanoparticles, on the environment using aquatic organisms such as freshwater planktons, medaka fish, and daphnia. The new method such as WET (Whole Effluent Toxicity Test) is introduced to clarify the effect of the unknown chemical substances and mixture effects of the numerous chemical compounds included in ambient water or industrial wastewater. Some measures are also proposed to reduce the ecotoxicity. It is important to combine the approaches using experiments, observations, and analyses to better understand the ecosystem.
