Outline of Final Research Achievements

This study examined the uptake and depuration rate constants of polychlorinated biphenyl (PCB) and polybrominated diphenyl ether (PBDE) to develop a bioaccumulation model for a variety of aquatic organisms. Bioaccumulation and metabolism experiments were performed to determine the detailed rate constants, which are model parameters. A food web bioaccumulation model for an estuary of the Ariake Sea was constructed. The model incorporating the rate constants was used to predict the PCB and PBDE concentrations of six species of aquatic organisms. The estimated results agreed well with the observed PCB and PBDE concentrations in organisms collected in this area. This model will contribute to the advancement of exposure assessment methods for aquatic organisms.
