    A book by Kruckeberg () described the ora, vegetation, geology, soils, and management problems of serpentine in California from a primarily botanical viewpoint. Our book considers a broader geographic scope, and also provides more in-depth accounts of the geology (part I), soils (part II), and plant communities (part III) of serpentine. The book series Arsenic in the EnvironmentProceedings is an inter- and multidisciplinary source of information, making an effort to link the occurrence of geogenic arsenic in different environments and the potential contamination of ground- and surface water, soil and air and their effect on the human society.

    Abstract Book Milan, Italy, September , We computed the focal mechanisms for the major and best recorded earthquakes occurring in the area. One cluster located at few kilometers north-west of the summit craters shows fault mechanisms of the deeper events with nearly horizontal P-axes striking NNW-SSE. A segment of the Sicilian. It has been reported that Tiberius, Caesar around 34 A.D., sent troops to Ostia in order to extinguish a fire in the harbour as noticed from the red patchy sky – the aurora seen from some distance (Seneca ∼60 A.C.). The various types of aurora and their excitation mechanisms are described in .

Although many oxidation–reduction (redox) reactions Oxidation-reduction mechanisms in iron-bearing phyllosilicates book reversible, they are included here because many of the redox reactions that influence the fate of toxicants are irreversible on the temporal and spatial scales that are important to toxicity.

The reductive capacities of iron-bearing sulfide (pyrite), hydroxide (green rust; GR SO4), and oxide (magnetite) minerals for Cr(VI) and tetrachloroethylene (PCE) were 1−3 orders of magnitude greater than those of iron-bearing phyllosilicates (biotite, vermiculite, and montmorillonite).

However, sequestration of Tc(IV) into Fe(III)-bearing phases, such as goethite, iron-bearing phyllosilicates and, perhaps, siderite, may ameliorate concerns over the mobility of Tc.

Proc Natl Acad Sci USA Frisia S, Borsato A, Fairchild AJ, McDermott F () Calcite fabrics, growth mechanisms, and environments of formation in speleothems from the Italian Alps and SW Ireland. The predominant forms of As in groundwater are the inorganic species arsenate [As(V)] and arsenite [As(III)], and both are known to be highly toxic.

The chemistry of arsenic in aquatic systems is complex, and consists of oxidation-reduction, ligand exchange, precipitation, and adsorption. Presently, microbial reduction of ferric iron and structural iron(III) in iron-bearing phyllosilicates (e.g., smectites) is favored as an explanation of gleying (Ottow, a,; Benzine et al., ).

The gray green minerals that are formed are amorphous iron(II)–iron(III) containing minerals with a general formula of Fe3(OH)8. Iron-bearing clay minerals are predominant in soils and sediments, and they undergo oxidation-reduction cycle as a result of natural and artificialprocesses such as wetting/drying cycles and plant root respira-tion.

However, the kinetics and mechanisms of multiple redox cycles of. The bilateral cooperation between the Academy of Sciences of the Czech Republic and Chinese Academy of Science provided an opportunity for preliminary investigation of this material which is deposited in the collections of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, as well as to see the localities in the field.Transcript.
