The structural identity of humic substances (HS) in the soil is a highly debated issue in the
soil sciences. Although the complexity and structural characteristics that determine the …

Optical measurements (absorbance and fluorescence) are widely used to track dissolved
organic matter (DOM) quantity and quality in natural and engineered systems. Despite many …

This study highlights differences in conformational and physicochemical characteristics of
bovine skim milk and micellar casein from cows of different β-casein phenotypes. These …

Terrestrial dissolved organic matter (DOM) plays critical roles in many biotic and abiotic
environmental reactions as well as in water treatment. Its structure is therefore of great …

Temperature-dependent IR spectroscopy capable of revealing specific changes in the band
intensities, positions, and shape was used to increase the information on humic substances …

Natural organic matter (NOM) components measured with ultrahigh-resolution mass
spectrometry (UHRMS) are often assessed by molecular formula-based indices, particularly …

The goal of this study was to establish a relationship between the optical properties of soil
dissolved organic matter (DOM) and acidic functions carried out by its individual …

Humification is a ubiquitous natural process of biomass degradation that creates
multicomponent systems of nonliving organic matter, including dissolved organic matter …

Direct comparison of high-resolution mass spectrometry (HRMS) data acquired with different
instrumentation or parameters remains problematic as the derived lists of molecular species …

Abstract The Ob-Irtysh River system is the seventh-longest one in the world. Unlike the other
Great Siberian rivers, it is only slightly impacted by the continuous permafrost in its low flow …
