Contaminant loading and competitive access of Pb, Zn and Mn(III) to vacancy sites in biogenic MnO2

Louise Helene Soegaard Jensen, Jasquelin Peña

The scavenging properties of MnO2 are largely attributed to sorption on layer vacancy sites. However, co-occurrence of Mn(II, III) with MnO2 can change mineral reactivity by modifying its Mn(III) content or number of free vacancy sites. These processes are ...

Assessment of water resource contamination by pesticides in vegetable-producing areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann, Jean-Jacques Stéphane Nfon Dibie, Morgan Fargues

This study proposes a comprehensive approach to investigate water resource contamination by pesticides under the specific climatic and hydrological conditions of the Sudano-Sahelian climate. Samples were collected from tradi- tional wells, boreholes, and a ...

Specific and total N -nitrosamines formation potentials of nitrogenous micropollutants during chloramination

Urs von Gunten, Florian Frédéric Vincent Breider, Caroline Gachet Aquillon, Andrea Piazzoli

N-nitrosamines are a group of potent human carcinogens that can be formed during oxidative treatment of drinking water and wastewater. Many tertiary and quaternary amines present in consumer products (e.g., pharmaceuticals, personal care and household prod ...

On-Chip Spyhole Nanoelectrospray Ionization Mass Spectrometry for Sensitive Biomarker Detection in Small Volumes

Hubert Girault, Liang Qiao, Xiaoqin Zhong, Géraldine Margaretha Alice Stauffer

A polyimide microfluidic chip with a microhole emitter (Ø 10–12 μm) created on top of a microchannel by scanning laser ablation has been designed for nanoelectrospray ionization (spyhole-nanoESI) to couple microfluidics with mass spectrometry. The spyhole- ...

Fate of Cr(III) during ozonation of secondary municipal wastewater effluent

Urs von Gunten, Caroline Gachet Aquillon

In the present study, the fate of trivalent chromium (Cr(III)) during ozonation of ultrapurified water and wastewater effluent was investigated. In experiments conducted in phosphate buffered ultrapurified water, O3 alone in excess was inefficient to oxidi ...

A Microfluidic Biodisplay

Sebastian Maerkl, Francesca Volpetti, Ekaterina Emilova Petrova

Synthetically engineered cells are powerful and potentially useful biosensors, but it remains problematic to deploy such systems due to practical difficulties and biosafety concerns. To overcome these hurdles, we developed a microfluidic device that serves ...

Effects of episodic rainfall on a subterranean estuary

David Andrew Barry, Clare Robinson

Numerical simulations were conducted to examine the effect of episodic rainfall on nearshore groundwater dynamics in a tidally influenced unconfined coastal aquifer, with a focus on both long- (yearly) and short-term (daily) behaviour of submarine groundwa ...

Potential for Fault Reactivation Due to CO2 Injection in a Semi-Closed Saline Aquifer

Lyesse Laloui, Victor Vilarrasa Riano, Roman Makhnenko

CO2 injection in extensive saline aquifers that present no faults is unlikely to damage the caprock sealing capacity. In contrast, CO2 injection in closed reservoirs will induce a large pressure buildup that may reactivate the low-permeable faults that bou ...
