Statistical Modeling of Global Geogenic Arsenic Contamination in Groundwater
Manouchehr Amini,Karim C. Abbaspour,Michael Berg,Lenny H. E. Winkel,Stephan J. Hug,Eduard Hoehn,Hong Yang,C. Annette Johnson +7 more
TL;DR: A large database of measured arsenic concentration in groundwaters from around the world as well as digital maps of physical characteristics such as soil, geology, climate, and elevation are used to model probability maps of global arsenic contamination.
Journal ArticleDOI
Environmental selenium research: from microscopic processes to global understanding.
Lenny H. E. Winkel,Lenny H. E. Winkel,C. Annette Johnson,Markus Lenz,Markus Lenz,Tim Grundl,Olivier X. Leupin,Manouchehr Amini,Laurent Charlet +8 more
TL;DR: The recent development of analytical techniques and methods enables accurate selenium measurements of environmental concentrations, which will lead to a better understanding of biogeochemical processes, which may enable us to predict the distribution of Se health hazards in areas where this is currently unknown.
Journal ArticleDOI
Quantitative Antimony Speciation in Shooting-Range Soils by EXAFS Spectroscopy
Andreas C. Scheinost,André Rossberg,Delphine Vantelon,Irene Xifra,Ruben Kretzschmar,Ann-Kathrin Leuz,H. Funke,C. Annette Johnson +7 more
TL;DR: In this article, the Sb speciation in soil samples from Swiss shooting ranges was determined using Sb K-edge X-ray absorption spectroscopy (XAS) and advanced statistical data analysis methods (iterative transformation factor analysis, ITFA).
Journal ArticleDOI
Predicting groundwater arsenic contamination in Southeast Asia from surface parameters
TL;DR: In this article, the authors presented maps pinpointing areas at risk of groundwater arsenic concentrations exceeding 10μg/l−1, using a logistic regression model calibrated with 1,756 aggregated and geo-referenced groundwater data points from the Bengal, Red River and Mekong deltas.
Journal ArticleDOI
Dissolution-precipitation behaviour of ettringite, monosulfate, and calcium silicate hydrate
TL;DR: In this paper, the stability of the cement minerals ettringite, monosulfate, and calcium silicate hydrate (C-S-H) was investigated to better understand the uptake of contaminants in waste-cement mixes.
