Bioavailable atmospheric phosphorous supply to the global ocean: A 3-D global modeling study
The atmospheric cycle of phosphorus (P) is parameterized here in a state-of-the-art global 3-D chemistry transport model, taking into account primary emissions of total P (TP) and soluble P (DP) associated with mineral dust, combustion particles from natur ...
Copernicus GmbH2016Photo-transformation of pedogenic humic acid and consequences for Cd(II), Cu(II) and Pb(II) speciation and bioavailability to green microalga
Humic substances (HS) play key role in toxic metal binding and protecting aquatic microorganisms from metal-induced stress. Any environmental changes that could alter HS concentration and reactivity can be expected to modify metal complexation and thus aff ...
Pergamon-Elsevier Science Ltd2015Kinetic studies on the first dihydrogen aquacomplex, [Ru(H2)(H2O)5]2+: Formation under H2 pressure and catalytic H/D isotope exchange in water
André Merbach, Lothar Helm, Gabor Laurenczy, Oleg Yazyev, Pascal Grundler
The ruthenium(II) hexaaqua complex [Ru(H2O)6]2+ reacts with dihydrogen under pressure to give the h2-dihydrogen ruthenium(II) pentaaqua complex [Ru(H2)(H2O)5]2+.The complex was characterized by 1H, 2H and 17O NMR: d H = -7.65 ppm, J HD = 31.2 Hz, d O = -80 ...
2006Community and cultivation analysis of arsenite oxidizing biofilms at Hot Creek
At Hot Creek in California, geothermally derived arsenite is rapidly oxidized to arsenate. This process is mediated by microorganisms colonizing the surfaces of submerged aquatic macrophytes in the creek. Here we describe a multifaceted approach to charact ...
2006Arsenic adsorption and oxidation at manganite surfaces. 1. Method for simultaneous of determination of adsorbed and dissolved arsenic species
Arsenic occurs in the +III oxidation state as a metastable species in oxic waters. Under oxic conditions, As(III) is both more mobile in natural waters and less efficiently removed by water treatment processes than As(V). Other oxidants, however, can react ...
