Specific components of dissolved organic matter (DOM) may serve as indicators the nitrate accumulation process in groundwater. However, precise mechanisms underlying enrichment based on DOM characterization groundwater systems remain unclear. This study aims to reveal sources and pathways through application three-dimensional Excitation Emission Matrices (EEM) Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS). The presence fresh which show high biological activity, resulting from leaching subsoil excessive input manure sewage, contributes elevated levels porous aquifer. main contributors inorganic are formulas containing a higher number nitrogen atoms. three atoms, characterized by larger mass weights lower H/C ratios, closely associated with readily bioavailable fraction. Consequently, observed rate samples can be attributed bioavailability nitrogen-containing molecules. provides molecular perspective its relationship systems, offering valuable insights for more accurate assessment potential stocks
