Component and fateFluorescence analysisBiological degradation of dissolved organic matter(DOM)regulates its structure and fate in river ecosystems.Previous views suggested that labile components were dominantly consumed by microbial metabolism.Here we provide new observations that a part of recalcitrant ...
Besides metal inclusions, refractory organic matters including humic/fulvic-like components are also a typical component of landfill leachate (Priyanka & Saravanakumar, 2023). 3D EEM is extensively used for the characterization of dissolved organic matter during organic waste fermentation (Li et al., ...
Humic substances (HSs), as the dominant components of soil organic matter (50%‒75%), are a kind of heterogeneous supramolecular architectures with aromatic, aliphatic, and carbohydrate fragments1. The content of HSs in the soil carbon pool has a remarkable effect on the agroenvironmental qualit...
As a major component of WSOM, HULIS is also considered as a significant contributor to the light absorption. The light absorption of water-insoluble OA fractions, on the other hand, has not been studies widely. Chen et al.23 and Huang et al.24 extracted and fractionated OA into different ...

Principal Component Analysis (PCA) was used to investigate possible correlations between conventional Lowry and Dubois methods, Liquid Chromatography coupled to Organic Carbon and Organic Nitrogen Detection (LC-OCD-OND) and 3DEEM. 3DEEM data were analyzed using the volume of fluorescence (Φ) ...

The humic‐like component with long‐emission wavelengths (L‐HULIS) was identified as a secondary source tracer of BrC. This was confirmed by correlating PARAFAC components with secondary organic aerosol tracers and molecular oxidation indices obtained from Fourier transform ion cyclotron r...
