Abiotic retention of nitrogen and dissolved organic matter by forest mineral soils [PDF]

, 2006
The effect of NO3- deposition on NH4 +, DON, and DOC retention as well as abiotic NO3 - retention via the hypothesized ferrous wheel mechanism was examined in oxic and anoxic tropical and oxic temperate soils using sorption isotherm experiments ...

Tracing groundwater flow and sources of organic carbon in sandstone aquifers using fluorescence properties of dissolved organic matter (DOM) [PDF]

, 2008
The fluorescence properties of groundwaters from sites in two UK aquifers, the Penrith Sandstone of Cumbria and the Sherwood Sandstone of South Yorkshire, were investigated using excitation-emission matrix (EEM) fluorescence spectroscopy.

The significance of dissolved organic matter photodegradation as a source of ammonium in natural waters

Oceanologia, 2002
Samples of sea, river and pond water of different absorbance were exposed to artificial radiation resembling sunlight in the UV range. A statistically significant increase in ammonium concentration was detected in pond water of the highest absorbance ...

Universal molecular structures in natural dissolved organic matter

Nature Communications, 2018
Dissolved organic matter (DOM) in aquatic systems is among the most complex molecular mixtures known. Here the authors show that a major component in DOM is molecularly indistinguishable in marine and freshwater environments, which could reflect ...

Elemental and isotopic composition of river water during a flood event in agricultural watershed: insight of sources and pathways of water and terrestrial derived matter [PDF]

, 2012
Flood event in agricultural watershed represents 64% of water discharge but up to 71% of dissolved organic carbon and 94 of total suspended matter export.

Congener specific organic carbon normalized soil and sediment-water partitioning coefficients for the C1 through C8 perfluorinated alkylsulfonic and alkylcarboxylic acids [PDF]

, 2009
Organic carbon normalized soil and sediment-water partitioning (Koc) coefficients were estimated for all C1 through C8 perfluorinated alkylsulfonic acid (PFSA) and alkylcarboxylic acids (PFCA) congeners.

Partition of copper between dissolved and particulate phases using aluminum oxide as an aquatic model phase: effects of pH, solids and organic matter

Journal of the Brazilian Chemical Society, 2000
The sorption of copper ions from aqueous solutions onto modified aluminum oxide was investigated as a function of pH, solids concentration and both particulate and dissolved organic matter.

Current methods overestimate coastal blue carbon potential

Limnology and Oceanography Letters
Blue carbon ecosystems buffer climate change via sediment carbon capture, gaining elevation and mitigating sea level rise in the process. Carbon sequestration and accretion estimates share a common methodology, whereby dry masses are converted to volume ...

2007 Great Bay Organic Nitrogen and Light Extinction Monitoring Program [PDF]

, 2008
Nitrogen is most often considered to be the limiting nutrient for plant growth in marine waters. As a result, knowledge of nitrogen loading and ambient water-column concentrations are considered to be critical to understanding the response of aquatic ...
