Colloidal Size and Redox State of Uranium Species in the Porewater of a Pristine Mountain Wetland

Rizlan Bernier-Latmani, Barbora Bártová, Manon Frutschi, Gabrielle Dublet, Ashley Richards Brown, Giada Chantal Zünd

Uranium (U) speciation was investigated in anoxically preserved porewater samples of a natural mountain wetland in Gola di Lago, Ticino, Switzerland. U porewater concentrations ranged from less than 1 mu g/L to tens of mu g/L, challenging the available ana ...

Implementation of a constructed wetland for the sustainable treatment of water in shrimp farming activities, Mekong delta, Vietnam

Pierre Rossi, Florian Frédéric Vincent Breider, Vincent Jean Jacques Marie Cochevelou

In the Mekong delta, inland-based shrimp breeding is a profitable activity requiring significant inflow of high quality freshwater. In turn, discharge of substantial loads of poor quality effluents causes salinization and eutrophication of adjacent water b ...

Reactions of aliphatic amines with ozone: Kinetics and mechanisms

Urs von Gunten, Sung Eun Lim

Aliphatic amines are common constituents in micropollutants and dissolved organic matter and present in elevated concentrations in wastewater-impacted source waters. Due to high reactivity, reactions of aliphatic amines with ozone are likely to occur durin ...

Chlorinated ethene plume evolution after source thermal remediation: Determination of degradation rates and mechanisms

Christof Holliger, Julien Maillard, Alexandra Marie Murray, Jérémy Zimmermann

The extent, mechanism(s), and rate of chlorinated ethene degradation in a large tetrachloroethene (PCE) plume were investigated in an extensive sampling campaign. Multiple lines of evidence for this degradation were explored, including compound-specific is ...

Enhanced mineralization of atrazine by surface induced hydroxyl radicals over light-weight granular mixed-quartz sands with ozone

Stefanos Giannakis, Jun Ma, Da Wang, Shuang Song

A light-weight granular mixed-quartz sand (denoted as L-GQS) combined with stirring-assisted bubble column reactor was firstly applied in catalytic ozonation of atrazine. The L-GQS, with a density of 2.36 g cm(-3) and average diameter of ca. of 4 mm, was r ...

A systematic investigation on the bactericidal transient species generated by photo-sensitization of natural organic matter (NOM) during solar and photo Fenton disinfection of surface waters

César Pulgarin, Stefanos Giannakis, Mona Kohantorabi, Ling Feng

In this work, the role of dissolved oxygen in the solar and the photo-Fenton-mediated E. coli inactivation process was put under scrutiny. The effect of transient species that were produced in the presence of various natural organic matter isolates (NOM), ...

Oxygen consumption in seasonally stratified lakes decreases only below a marginal phosphorus threshold

Alfred Johny Wüest, Robert Vincent Schwefel

Areal oxygen (O-2) consumption in deeper layers of stratified lakes and reservoirs depends on the amount of settling organic matter. As phosphorus (P) limits primary production in most lakes, protective and remediation efforts often seek to reduce P input. ...

Simultaneous detection of C2H6, CH4, and δ13C-CH4 using optical feedback cavity-enhanced absorption spectroscopy in the mid-infrared region: Towards application for dissolved gas measurements

Jérôme Chappellaz, Daniele Romanini

We present high-resolution measurements of carbon monoxide (CO) concentrations from a shallow ice core of the North Greenland Eemian Ice Drilling project (NEEM-2011-S1). An optical-feedback cavity-enhanced absorption spectrometer (OF-CEAS) coupled to a con ...
