Dissolved organic matter contribution to rain water, throughfall and soil solution chemistry [PDF]

, 1999
A method is proposed to determine the acidbase properties of natural water samples containing relatively high amounts of dissolved organic matter.

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]

, 2011
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Application of multivariate methods and geoestatistics to model the relationship between CO2 emissions and physicochemical variables in the Hidrosogamoso reservoir, Colombia

Acta Limnologica Brasiliensia, 2020
: Aim This article deals with the estimation of a model for CO2 emissions in the Hidrosogamoso reservoir based on the organic matter level and water quality.

Removal of terrestrial DOC in aquatic ecosystems of a temperate river network [PDF]

, 2015
Surface waters play a potentially important role in the global carbon balance. Dissolved organic carbon (DOC) fluxes are a major transfer of terrestrial carbon to river systems, and the fate of DOC in aquatic systems is poorly constrained.

Predator‐induced changes in dissolved organic carbon dynamics [PDF]

Oikos, 2018
The fate of dissolved organic carbon (DOC) is partly determined by its availability to microbial degradation. Organisms at upper trophic levels could influence the bioavailability of DOC via cascading effects on primary producers and bacteria. Here we experimentally tested whether the presence of fish in aquatic food webs can indirectly affect the ...

Distribution of Organic Carbon in the Sediments of Xinxue River and the Xinxue River Constructed Wetland, China. [PDF]

PLoS ONE, 2015
Wetland ecosystems are represented as a significant reservoir of organic carbon and play an important role in mitigating the greenhouse effect. In order to compare the compositions and distribution of organic carbon in constructed and natural river ...

Characterization of Dissolved Organic Matter in River Water by Conventional Methods and Direct Sample Analysis-Time of Flight-Mass Spectrometry

Journal of Chemistry, 2016
The dissolved organic matter in surface waters is composed of fractions of different molecular weight and polarity, characteristics that determine their capacity for complexing different types of pollutants and their environmental impact.

Concentration of Total Organic Carbon and Its Fractions in Surface Water in Poland and Germany

Proceedings, 2020
Total organic carbon (TOC) present in surface water consists of different fractions like dissolved organic carbon (DOC) or biodegradable dissolved organic carbon (BDOC).

Dissolved Organic Carbon Reference Material Program [PDF]

Eos, Transactions American Geophysical Union, 2005
Analytical chemistry benefits from uniformly applied and readily accessible reference materials to assess the accuracy of experimental results. Without assessment, experimental findings are best considered with a healthy dose of skepticism. For several chemical analyses, reference materials are available commercially Amino acids, for example, are ...
