Arsenic in Ground Water: Geochemistry and Occurrence

Book Description

Potable water supplies that contain arsenic concentrations high enough to pose a human health hazard are a problem of international proportion. Surface water and ground water are both at risk of arsenic contamination. However, most incidences of high concentrations of arsenic have been reported for ground water, which is the subject of this book. The geochemistry of arsenic in aqueous environments is complex. This book consolidates much of what is known about the geochemistry of arsenic and provides new information on relationships between high concentrations of arsenic in ground water and geochemical environments. The subject matter of this book ranges in scope from molecular-scale geochemical processes that affect the mobility of arsenic in ground water, to arsenic contaminated ground water at the national scale. Chapters were contributed by an international group of research scientists from a broad range of backgrounds.
Information includes reviews of existing thermodynamic data for arsenic containing mineral phases and aqueous arsenic species, factors that affect adsorption of arsenic in common ground water environments, and spectroscopic techniques used to determine the chemical reactions controlling arsenic partitioning between solid and liquid phases at particle-water interfaces. A significant portion of this book is devoted to regions where high concentrations of arsenic in ground waters have a natural source. The original source of arsenic can vary; however, arsenic becomes concentrated in the solid and aqueous phases of an aquifer given appropriate geochemical conditions. Often, high arsenic concentrations in the solid phase become mobile if there is a change in ground water chemistry, either natural or anthropogenically induced. Research presented in this book covers several different geologic settings and provides explanations of the geochemical processes that have caused the arsenic concentrations observed in ground water. In situ remediation of arsenic-contaminated ground water can provide a relatively inexpensive alternative to above ground treatment. One chapter of this book discusses natural remediation of an aquifer where naturally occurring arsenic was mobilized by leachate from a landfill. Two chapters discuss results from field experiments designed to alter aquifer geochemistry in order to remove arsenic from ground water prior to withdrawal.
This book will be of interest to scientists working in the field of arsenic, health professionals interested in arsenic exposure, and water-resource managers and regulators.

Book Description

Venomous Earth is the compelling story of the worst chemical disaster in human history - unfolding now. It explores the geology, politics and biology of why tens thousands of people are dying, hundreds of thousands developing cancer and tens of millions of people are at risk in Bangladesh, India and beyond, from arsenic-contaminated well water. Andrew Meharg compares this scenario with that in other areas of the world where drinking water is tainted with arsenic, such as extensive areas of South Western USA, the Alto Plano of South America and New Zealand's volcanic regions. He details historical precedents spanning thousands of years in mining and smelting communities, and due to the widespread use of arsenic in alchemy, farming, medicine and manufacturing. His tale takes in William Morris, Paracelsus, George W Bush and a cosmetic that killed two popes. Finally Venomous Earth looks at how the current arsenic crisis is to be tackled and highlights new challenges to our ongoing struggle with the toxic element.

Book Description

With contributions from world-renowned experts in the field, this book explores developments in the transport kinetics, seasonal cycling, accumulation, geochemistry, transformation, and toxicology of arsenic. It details advances in the prevention and control of arsenic and arsenic compounds in the air, soil, and water and offers analytical methods for the detection and study of arsenic in the environment and human body. Providing bioremediation techniques for effective treatment of contaminated water supplies, the book discusses factors that influence the removal of arsenic from water as well as diurnal and seasonal variations in the arsenic concentration of surface water supplies.

Book Description

More than ten million `poison gas' shells, mortar bombs, etc., lie hidden in Europe, many of them relics from World War I. Some were fired and failed to detonate, others were abandoned in old ammunition dumps. Most retain their load of chemical warfare (CW) agents. They are turned up daily in the course of farming and construction. Many European nations have permanent departments concerned with their collection and destruction.
Old munitions, when discovered, are usually heavily corroded and difficult to identify. Is it a CW munition? Or an explosive? If CW, what agent does it contain? Once identified, one has to select a destruction method. Some of the methods that have been proposed are less than perfect, and are often complicated by the presence of extraneous chemicals, either mixed with the CW agents during manufacture or formed over decades in the ground.
Of particular interest are the insiders' reports on the German CW programmes of both World Wars, and the current status of Russian chemical armaments.

Book Description

This collected volume of authoritative articles represents the state-of-the-art in arsenic research. Arsenic experts from around the world, participants in the Fourth International Conference on Arsenic Exposure and Health Effects organized by the Society of Environmental Geochemistry and Health in 2000, present their critical findings.

Book Description

An element in the earth's crust, an additive in livestock feed. a medicine in early civilization—and the &#quot;toxin of toxins&#quot; A pervasive part of our natural environment and everyday lives. arsenic has nonetheless earned a niche in history as a substance of diabolical suppleness. Part II of the first comprehensive and up-to-date two-volume study of arsenic, Arsenic in the Environment is a self-contained work that examines arsenic's complex and potentially deadly chemistry, stressing its effect on human health and the surrounding ecosystem. Examining new and unexplored aspects of the toxin, Part II features original research from some of the world's foremost scientists on:

Health effects of environmental arsenic
Toxicity and metabolism of inorganic and methylated arsenicals
Effects of arsenic on DNA synthesis of human lymphocytes
Estimation of human exposure to and uptake of arsenic found in drinking water
Arsenic hazards to plants and animals

Offering a host of subjects of particular interest to toxicologists, medical researchers, public health officials, and industrial hygienists, Part II of Arsenic in the Environment is an indispensable reference that sheds new light on arsenic's unique chemistry as well as its health and environmental effects.

Book Description

Fossil communities, chiefly benthic, from Silurian and Devonian rocks are looked at in detail within this book. Discussion of their environmental and evolutionary significance provides a unique ecological view of this intensively studied part of the stratigraphic column. It is hoped that this case-study will illustrate a new trend for palaeontological research and synthesis that could be applied to other time intervals. Forty contributions from all parts of the world discuss and exemplify the general principles of this massive compilation and provide descriptions of many of the shelly mid-Silurian and early Devonian benthic communities in encyclopaedic form. Biostratigraphers and palaeontologists, as well as evolutionists and ecologists, concerned with fossil communities and their evolution will find this volume of interest. This book forms the final report of IGCP Project 53.

Book Description

Special Papers in Palaeontology, published by The Palaeontological Association, is a series of substantial separate works conforming to the style of the Palaeontology journal. This issue investigates the thelodonts and putative chondrichthyans from rocks of upper Llandovery (Lower Silurian) to Lochkovian (Lower Devonian), and from Baillie-Hamilton and Cornwallis islands, Arctic Canada. It presents new anatomical information which will allow greater precision in future phylogenetic studies of thelodonts and related vertebrates.
