摘要

The purpose of this study was to evaluate the applicability of the AQUATOX model and to suggest a methodology for its practical use as an ecological toxicity model in Korea. Paldang reservoir was selected as the study area, and the BASINS/WinHSPF watershed model was used in conjunction with AQUATOX model to provide a linked simulation of the Paldang watershed. The AQUATOX model was run based on the simulation results of WinHSPF. AQUATOX was used to perform an analysis of the ecological state and characteristics of the Paldang reservoir and the ecological impact of toxicants; alachlor, paraquat, and copper sulfate. In the case of alachlor, which has been classified as a second-degree toxic material for fish, the biomass of minnow and bass declined considerably when the inflow concentration was above 100 mu g/L. In the case of paraquat, the biomass of minnow and bass declined significantly when the inflow concentration was 10 mu g/L. Biomass of daphnia and bluegill was significantly decreased due to the copper sulfate. The AQUATOX model could be considered to be applicable to water bodies in Korea and can be used with existing watershed models to determine the total maximum daily load (TMDL). Seasonal or monthly ecological monitoring data of common species should be provided to increase its feasibility.
