Taschenbuch. Condition: Neu. Neuware -The description of synthesis, characterization, spectral properties and solid state molecular structures of some new unsymmetrical alpha-aryltellurated ketonyl derivatives is the theme of this book. Electrophilic substitution of methylketones with aryltellurium trichlorides afforded aryl(acylmethyl)tellurium dichlorides, Ar(RCOCH2)TeCl2. The chosen aryl ligands viz. mesityl (2,4,6-Me3C6H2; Mes), 1-naphthyl (1-C10H7; Np) and anisyl (4-MeOC6H4; Anisyl) and methylketones with R = mesityl, t-butyl, i-propyl, ethyl possess varying steric and electronic effects and are known for their ability to cause various conformations and cell packing. These tellurium(IV) derivatives after reduction afforded unsymmetrical ż-aryl tellurated ketones, RCOCH2TeAr (R = Mes, t-Bu and i-Pr) in situ and were characterized by isolating their halogenated Te(IV) products. Attempts to isolate these arylalkyltellurium(II) compounds were successful for MesCOCH2TeMes, MesCOCH2TeNp and i-PrCOCH2TeMes, while in other cases decomposition resulted in Ar2Te2 and the parent ketones Shon. In Last Chapter we also deals with our efforts to explore Complexes of Mercury(II) Halides with ortho Aryltellurated Schiff Bases.Books on Demand GmbH, Überseering 33, 22297 Hamburg 132 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The health of millions of people worldwide is negatively impacted by chronic exposure to elevated concentrations of geogenic fluoride in groundwater. By this health effects including dental mottling and skeletal fluorosis, the World Health Organization maintains a maximum guideline of 1.5 mg/L in drinking water. As groundwater quality were not regularly tested in many of areas, it is often that the unknown if the water in a given well or spring contains harmful levels of fluoride. Here we present a state-of-the-art global fluoride hazard map based on a machine of learning and the hotspots indicated through the groundwater fluoride hazard map included the parts of central Australia, western North America and eastern Brazil and many areas of Africa and Asia. Of the approximately 180 million people potentially affected worldwide, most reside in Asia (51ż59% of total) and Africa (37ż46% of total), with the latter representing 6.5% of the continentżs population. In Africa contains 14 of the top 20 affected countries in terms of population at risk. We also illuminate and discuss the key globally relevant hydrochemical and environmental factors related to fluoride accumulation.Books on Demand GmbH, Überseering 33, 22297 Hamburg 140 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -La salud de millones de personas en todo el mundo se ve afectada negativamente por la exposición crónica a concentraciones elevadas de fluoruro geogénico en las aguas subterráneas. Por estos efectos sobre la salud, entre los que se incluyen el moteado dental y la fluorosis esquelética, la Organización Mundial de la Salud mantiene una directriz máxima de 1,5 mg/L en el agua potable. Dado que la calidad de las aguas subterráneas no se analiza con regularidad en muchas zonas, a menudo se desconoce si el agua de un determinado pozo o manantial contiene niveles nocivos de flúor. Aquí presentamos un mapa mundial de riesgos de fluoruro basado en una máquina de aprendizaje y los puntos conflictivos indicados mediante el mapa de riesgos de fluoruro en aguas subterráneas incluían las zonas del centro de Australia, el oeste de Norteamérica y el este de Brasil, así como muchas zonas de África y Asia. De los aproximadamente 180 millones de personas potencialmente afectadas en todo el mundo, la mayoría reside en Asia (51-59% del total) y África (37-46% del total), representando esta última el 6,5% de la población del continente.
