Research Abstract |
We present a method to estimate the spatial distribution of sediment by using particle-size distribution and chemical composition. For particle-size analysis, organic matter was removed from sediment using H_2O_2. The spatial distribution of chemical composition and sediment removed organic matter showed clearly the distribution of impacts of sediments from the Tama River and Tokyo bay in Keihin Unga, Tokyo Bay, Japan. The result demonstrates the feasibility of the method to reduce uncertainty in interpreting the spatial distribution of impacts of sediment from some sources.
