To measure chromophoric properties of DOM in aquatic environments is relatively simple, but similarities in properties among extensive DOM samples make it difficult to identify characteristics that indicate different sources of DOM. We conducted a fi

To elucidate the molecular characteristics of dissolved organic matter (DOM) in Lake Baikal, 3D excitation-emission matrix spectroscopy and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) were employed. From the linear relatio

In the limnological environments, dissolved organic matter (DOM) consists of various organic molecules that come from allochthonous origin (e.g. riverine humic substances) and autochthonous origin (e.g. carbohydrates and proteins), and more than 90%

The dissolved organic carbon (DOC) concentrations in mesotrophic Lake Biwa were determined by a total organic carbon (TOC) analyzer, and DOC molecular size distributions were determined by size exclusion chromatography (SEC) using a fluorescence dete
