| Outline of Final Research Achievements |
Studies on effect of environmental radionuclide were conducted in high pollution wetland such as river wetland in North Fukushima prefecture and low pollution wetland such as Lake Kasumigaura, Lake Hinuma, Ozegahara Mire and Kushiro mire. In those wetland in region richly endowed with nature, monitoring study of cumulative dose and transition rate of environmental radionuclide were conducted. Ecosystem functions were researched and analyzed on wetland ecosystem for purposes of evaluation approach of environmental radionuclide assessment. The water and material recycling and dynamic process of environmental radionuclide were observed in protected area and catchment basin using stable isotope analysis and ICP analysis of water. The environmental radioactivity in the lake bottom sediment and wetland plants were evaluated in several site. The organic supply and organic matter decomposition in sediment were influenced by temperature and oxygen content.
