The natural organic matter (NOM) in an aquifer is a complex mixture of substances, such as humic acids, fulvic acids, amino acids, carbohydrates, lipids, lignin, and waxes. From: Encyclopedia of Analytical Science (Second Edition), 2005 ...
Define Decay of organic matter. Decay of organic matter synonyms, Decay of organic matter pronunciation, Decay of organic matter translation, English dictionary definition of Decay of organic matter. n. 1. The act or result of decomposing; disintegration
F.C.Ugolini,R.L.Edmonds, inDevelopments in Soil Science, 1983 Decomposition processes The study of organic-matter decomposition in soil is of importance not only because a great deal of the energy captured byphotosynthesisis released by this process, but also because nutrients are mineralized or ...
definition Fe-rich and contain highly reactive Fe that is not pyritized—and, in cases, nearly pure chemical sediments like many banded iron formations (BIFs)8. The fate of organic matter, and biogeochemical cycling of climatically important trace gases, in Precambrian sediments is thus ...

Dependence of an organic-matter system’s persistence on its complexity By definition, the preservation efficiency functionB(t) represents the fraction of the organic matter at aget(i.e., the waiting time before degradation occurs), wheret = 0 is set at the time point when organic matter...
Chromophoric dissolved organic matter (CDOM) is the term that is most commonly used to describe compounds dissolved in natural waters that absorb ultraviolet or short-wavelength visible light energy. Other terms in past and present use include gelbstoff (Kalle, 1938)M. Schnitzer...
10.7.2.4Soil Organic Matter SOMis composed of a continuum of organic resources from freshplant residuesto stabilized organic matter (OM) or humus (Stevenson, 1994). Although this definition of SOM includes intactplant litter, in this review we will often distinguish between decomposition of litter ...

Dissolved organic matter (DOM) present in aquatic environments can influence the sorption behavior of organic contaminants in multiple ways. Most organic contaminants are hydrophobic; hence, DOM and HOCs may compete for sorption sites, thereby reducing sorption of HOCs on MPs (Yu et al. 2020). ...
