Abstract: For an environment assessment related with water pollution in river basin, an analysis of each process such as pollutant release, distribution and exposure processes is needed to link in significant scale. The purpose of this research is to build a hydrological river basin assessment model for an estimation of water pollution distribution and an assessment of damage on fish population by using the distributed runoff model. A target area of the proposed simulation is the Yodo River basin including the Lake Biwa. The simulation is performed for an estimation of the distribution of Nonylphenol and Linear Alkyl benzene Sulfonate by physical-based model. PBPK model is used to estimate the accumulation of chemical substances in fish body and the risk assessment of chemical substances is analyzed based on the simulated concentration of chemical substances.
