Outline of Final Research Achievements

Molecular size distributions of dissolved organic matter (DOM) in aquatic environments such as lake, river and sediment porewater were measured by size exclusion chromatography with total organic carbon detection, and then relationships between molecular size, biodegradability and chemical characteristics of DOM were evaluated.
We found that high-molecular-size (HMS) DOM was much greater in percent fraction as compared with the findings reported previously. The percent fraction of HMS DOM is likely related with its biodegradability and carbohydrates content. Furthermore, we succeeded in measuring quantitatively molecular size distribution of DOM in seawater for the first time.
