Characterization of Freshwater Natural Dissolved Organic Matter (DOM): Mechanistic Explanations for Protective Effects Against Metaltoxicity and Direct Effects on Organisms [PDF]

open access: yes, 2013
Dissolved organic matter (DOM) exerts direct and indirect influences on aquatic organisms. In order to better understand how DOM causes these effects, potentiometric titration was carried out for a wide range of autochthonous and terrigenous freshwater ...

Solubility Enhancement of Hexachlorobenzene in the Presence of Aldrich Humic Acid [PDF]

open access: yes, 1996
The binding of hexachlorobenzene to Aldrich Humic Acid was measured using the solubility enhancement method. In comparison with Kdoc values from previous studies, the value for Kdoc measured in this experiment shows that the affinity of a contaminant for

Treeline displacement may affect lake dissolved organic matter processing at high latitudes and altitudes

open access: yesNature Communications
Climate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes in soil organic matter. Eventually, soil organic matter is transported to alpine and subarctic lakes with yet unknown consequences for ...

Molecular characterization of dissolved organic matter (DOM) in seawater

open access: yes, 2000
Dissolved organic matter (DOM) plays an important role in the global carbon cycle (chapter 1). However, not much is known about the molecular composition and the origin of DOM. The study described in this thesis was conducted to gain more knowledge on the molecular composition and the origin of DOM.

Biogeochemical and Optical Analysis of Coastal DOM for Satellite Retrieval of Terrigenous DOM in the U.S. Middle Atlantic Bight [PDF]

open access: yes, 2012
Estuaries and coastal ocean waters experience a high degree of variability in the composition and concentration of particulate and dissolved organic matter (DOM) as a consequence of riverine/estuarine fluxes of terrigenous DOM, sediments, detritus and ...

Methane fluxes, microbial activities and community structures in a wet tundra of the Lena Delta [PDF]

open access: yes, 2005
Wet tundra environments of the Arctic are natural sources of the climate relevant trace gas methane. The underlying biogeochemical processes are not yet well understood.
