Journal ArticleDOI
Hazardous concentrations of selenium in soil and groundwater in North-West India
TL;DR: Although safe Se concentrations were found in Hisar, Haryana, yet high levels of As, Mo and U present in groundwater indicated its unsuitability for drinking purposes, intensive investigations should be started for better understanding of the problem of Se toxicity.
Journal ArticleDOI
Sediment capping in eutrophic lakes – efficiency of undisturbed calcite barriers to immobilize phosphorus
TL;DR: In this article, the application of a calcite barrier was investigated to prevent P release from eutrophic lake sediments, and different calcite materials varying in grain size, specific surface area (SSA) and roughness of the surface were applied.
Journal ArticleDOI
Geochemical processes underlying a sharp contrast in groundwater arsenic concentrations in a village on the Red River delta, Vietnam
Elisabeth Eiche,Thomas Neumann,Michael Berg,Beth Weinman,Alexander van Geen,Stefan Norra,Zsolt Berner,Pham Thi Kim Trang,Pham Hung Viet,Doris Stüben +9 more
TL;DR: The spatial variability of As concentrations in aquifers of the Red River Delta, Vietnam, was studied in the vicinity of Hanoi as discussed by the authors, where two sites, only 700m apart but with very different As concentrations, were compared.
Journal ArticleDOI
Reactivity of the calcite–water-interface, from molecular scale processes to geochemical engineering
Frank Heberling,Dirk Bosbach,Jörg-Detlef Eckhardt,Uwe Fischer,Jens Glowacky,Michael Haist,Utz Kramar,Steffen Loos,Harald S. Müller,Thomas Neumann,Christopher Pust,Thorsten Schäfer,Jan Stelling,Marko Ukrainczyk,Victor L. Vinograd,Victor L. Vinograd,Marijan Vučak,Björn Winkler +17 more
TL;DR: In this article, the authors present a review of calcite-water-interface studies, including those performed in the framework of the joint research project "RECAWA" (re activity of ca lcite-wa ter-interfaces: molecular process understanding for technical applications).
Journal ArticleDOI
Early diagenetic processes during Mn-carbonate formation: evidence from the isotopic composition of authigenic Ca-rhodochrosites of the Baltic Sea
TL;DR: In this article, the formation of authigenic Ca-rich rhodochrosite (ACR) in sapropelic sediments of the Gotland Basin, Baltic Sea, is governed by deepwater renewal processes whereby saline water from the North Atlantic flushes the brackish anoxic Baltic Deeps.
