 · Environmental context The dissolution of minerals in fresh or seawaters is a critical environmental process. The rate at which substances dissolve, from the dissolution of calcite crystals to the weathering of mountains, can influence major global issues such as climate change and sealevel rise. This paper explores a new solutionbased rate equation for mineral dissolution that has profound ...

 · An experiment at the Institut LaueLangevin raises great hopes. The health of millions of people is threatened by the presence of arsenic in their drinking water. In countries such as India, Bangladesh, Vietnam, Taiwan and Argentina, tens of millions of people drink untreated water containing levels of arsenic between ten and one hundred times higher than that recommended by the World .

In this review, we discuss microbiological and molecular concepts of Microbially Induced Calcium Carbonate Precipitation (MICP) and their role in bioconcrete. MICP is a widespread biochemical process in soils, caves, freshwater, marine sediments, and hypersaline habitats. MICP is an outcome of metabolic interactions between diverse microbial communities with organic and/or inorganic .

The mineralogy of carbonate sediments in a deepsea environment is partly controlled by sedimentation and partly by dissolution of highmagnesian calcite and aragonite. In deepsea sediments (1000–2000m depth) of the Red Sea which were studied, the carbonate sediments are composed of highmagnesian calcite and lowmagnesian calcite with aragonite absent or present only in subordinate ...

Lead (Pb) is a common environmental pollutant, and its transport in surface waters and groundwater is controlled in part by sorption and precipitation reactions at mineral surfaces. Using in situ specular and resonant anomalous Xray reflectivity measurements, we investigated the interaction of the calcite (104) surface with a dilute Pb and EDTAbearing solution that is slightly ...
