Book Description
The first of four volumes, which examine non-ferrous precious and base metal mining, metallurgy and minting in the Middle Ages, encompasses the history of these activities during the years 425-1125. It describes the shift in the focus of world precious metal production from the Western Roman Empire -350), to the Sassanid and Byzantine Empires (350-650) and Central Asia (480-930). Central Asia dominated for almost half a millennium world precious and base metal production, before output collapsed and an industrial diaspora caused the foci of silver and gold production to shift to Europe and sub-Saharan Africa respectively (930-1125). Mining activity in Central Asia, 480-930 is examined in depth, as is also its impact on local society and the distribution of precious metals from there to China, India and South-east Asia, Asia Minor and, via the Trans-Pontine steppes, to Europe. It also explores the impact of this flow of Sassanid-Islamic silver and gold on European mining and monetary systems, when that trade was at its height (560-930) and the response of the Europeans to the great oSilver Famineo occasioned by the collapse of Central Asian production (930-1125).

Book Description
Arsenic is a very important contaminant of drinking water and other substances. It represents approximately half of the estimated carcinogenic potential in coal fly ash. This important new work is written by top international experts in the field who assess the impact of arsenic contamination on a wide variety of areas including distribution, regulation, safety, physiology and medicine.

Book Description
Much new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.

Book Description
of metal interactions with subcellular biochemical systems usually either are metabolites of the system affected (porphyrinurias) or represent some specific function of a cellular system being impaired (proteinurias). One typically finds a continuum of symptoms, from the subtle or so-called "no effect" bio chemical and physiological indicators of exposure to severe clinical disease and death. This continuum is the basis of much of the controversy since many health officials follow the traditional practice of applying the "threshold health-effect" concept in evaluating the problems of environmental exposure to metals. The past decade or so, however, has seen a vast increase in our understanding of the effects of elevated concentrations of toxic metals in local populations and ecosystems. At the same time, there is a growing awareness that the effects of the metals which occur naturally in the environment must be distinguished from those imposed by the pollutant fraction. This point was amply document ed in a recent study of cadmium intake and cadmium in a number of human tissues in Sweden, Japan, and the United States, which showed fairly conclu sively that the background exposure in Japan was about threefold higher than in the other two countries (2). One immediate implication is that any health ef fect studies of cadmium in Japan using control groups within that country are liable to underestimate the difference between the exposed and the control groups simply because of the the high "background" intake.

Book Description
Preface Uranium is a radioactive element and a heavy metal which is naturally occurring in ground and surface water. Although uranium is enriched in granites and gneiss ground water from these host rocks often shows low to intermediate uranium con centrations, while some ground waters from sandstone and carbonate aquifers show elevated uranium concentrations up to several hundred mg/1 without man made impact. On the other side, surface water contains increased anthropogenic uranium concentrations due to the intensive use of phosphate fertilizers and in mining areas due to mining and milling activities. Saxony and Thuringia both be ing states of the reunified Germany are probably an area where uranium mining activities have impacted the environment more severely than in any other part of the world. Thus, the federal government of Germany allocated huge amounts of money for the rehabilitation work, a unique proceeding without precedent in min ing history. In October 1995 the first international conference on Uranium Mining and Hydrogeology (UMM I) was held in Freiberg being organized by the Department of Geology at the technical University Freiberg by the support of the Saxon State Ministry of Geology and Environment. Due to the large scientific interest in the topic ofuranium a second conference (UMH II) took place in Freiberg in Septem ber 1998.
