Mechanisms of goethite dissolution in the presence of desferrioxamine B and Suwannee River fulvic acid at pH 6.5 [PDF]

open access: yes, 2013
Siderophores are Fe3+ specific low MW chelating ligands secreted by microorganisms in response to Fe stress. Low MW organic acids such as oxalate have been shown to enhance siderophore mediated dissolution of Fe3+ oxides.

Fulvic Acids and Viral Infections

open access: yesThe Open Conference Proceedings Journal, 2012
Fulvic acids are active principles in humic substances allowing big absorption of mineral ions from soil through vegetables. They are formed by large organic molecules having several reactive sites. Tested in mice and rats with radio- active labeled ions ( 45 Ca 2+ , 32 PO4 3- , 59 Fe 3+ and 131 I - ) in drinking water, it has been found that for even ...

Composition characteristics and metal binding capacity of dissolved organic matter in the agriculture‐dominated Tuhai River

open access: yesRiver, EarlyView.
Abstract An essential part of river ecosystems, dissolved organic matter (DOM) has an enormous effect on the transport and variability of heavy metals. Nonetheless, our understanding of how the DOM affects heavy metal behavior in agricultural rivers remains limited. In this research, the DOM characteristics and effects on heavy metals (Cu2+, Zn2+, and

Untangling nutrient co‐regulation of ombrotrophic peatland development

open access: yesBoreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...
