Shortlisted for the BMA Book Awards and Macavity Awards 2016 Fourteen novels. Fourteen poisons. Just because it's fiction doesn't mean it's all made-up ... Agatha Christie revelled in the use of poison to kill off unfortunate victims in her books; indeed, she employed it more than any other murder method, with the poison itself often being a central part of the novel. Her choice of deadly substances was far from random – the characteristics of each often provide vital clues to the discovery of the murderer. With gunshots or stabbings the cause of death is obvious, but this is not the case with poisons. How is it that some compounds prove so deadly, and in such tiny amounts? Christie's extensive chemical knowledge provides the backdrop for A is for Arsenic, in which Kathryn Harkup investigates the poisons used by the murderer in fourteen classic Agatha Christie mysteries. It looks at why certain chemicals kill, how they interact with the body, the cases that may have inspired Christie, and the feasibility of obtaining, administering and detecting these poisons, both at the time the novel was written and today. A is for Arsenic is a celebration of the use of science by the undisputed Queen of Crime.

Rice is the staple food for half of the world’s population. Consumption of rice is the major exposure route globally to the class one, non-threshold carcinogen inorganic arsenic. This book explains the sources of arsenic to paddy soils and the biogeochemical processes and plant physiological attributes of paddy soil-rice ecosystems that lead to high concentrations of arsenic in rice grain. It presents the global pattern of arsenic concentration and speciation in rice, discusses human exposures to inorganic arsenic from rice and the resulting health risks. It also highlights particular populations that have the highest rice consumptions, which include Southern and South East Asians, weaning babies, gluten intolerance sufferers and those consuming rice milk. The book also presents the information of arsenic concentration and speciation in other major crops and outlines approaches for lowering arsenic in rice grain and in the human diet through agronomic management.

Arsenic - Analytical and Toxicological Studies is a collection of original works focused on arsenic occurrence and chemistry, methods for arsenic determination and removal and arsenic toxicity and health risks. The most commonly used techniques for arsenic quantification and speciation, such as atomic absorption spectrometry, inductively coupled plasma-mass spectrometry, and inductively coupled plasma-emission spectrometry, among others, and the various procedures applied for arsenic separation and removal are exhaustively described. The mechanism of arsenic-induced toxicology, involving arsenic interaction with critical thiols in proteins and the health risks associated with exposure to arsenic, is also discussed.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pages: 25. Chapters: Arsenic poisoning, Arsenic toxicity, Arsenic contamination of groundwater, GFAJ-1, Arsenic biochemistry, Carancas impact event, Marsh test, Bradford sweets poisoning, Toroku arsenic disease, Sono arsenic filter, Grainger challenge. Excerpt: Arsenic ( ) is a chemical element with the symbol As, atomic number 33 and relative atomic mass 74.92. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. It was first documented by Albertus Magnus in 1250. Arsenic is a metalloid. It can exist in various allotropes, although only the grey form has important use in industry. The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in automotive batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon. A few species of bacteria are able to use arsenic compounds as respiratory metabolites, and are arsenic-tolerant. Arsenic is notoriously poisonous to multicellular life due to the interaction of arsenic ions with protein thiols. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides (treated wood products), herbicides, and insecticides. These applications are declining, however, as many of these compounds are being phased out. Arsenic poisoning from naturally occurring arsenic compounds in drinking water remains a problem in many parts of the world. The three most common allotropes are metallic grey, yellow and black arsenic, with grey being the most common. Grey arsenic ( -As, space group #166 R-3m) adopts a double-layered structure consisting of many interlocked ruffled six-membered rings. Nearest and next-nearest neighbors form a distorted octohedra...

This book presents an overview of the chemistry, geology, toxicology and environmental impacts of arsenic, presenting information on relatively common arsenic minerals and their key properties. In addition, it includes discussions on the environmental impacts of the release of arsenic from mining and coal combustion. Although the environmental regulations of different nations vary and change over time, prominent International, North American, and European guidelines and regulations on arsenic will be reviewed. Includes information on recent environmental catastrophes (e.g. Bangladesh and China) A thorough discussion of the arsenic cycle, including the cosmological origin of arsenic Includes Appendices providing extensive glossary and measurement conversion tables

This volume reports on the bench-scale testing of of 4 technologies: ion-exchange processes, sorption kinetics, coupled sorbent-membrane processes and coupled coagulation-ballasted-sedimentation processes. Volume 2 will focus on results of the full-scale demonstration testing.

With the lowering of the arsenic levels by the EPA, smaller utilities face a challenge to efficiently and cost-effectively monitor arsenic concentration. This project sought to develop a fast, safe easy-to-use and relatively inexpensive field method for that purpose as existing and newly introduced kits were found lacking in various ways. The new field method developed by this project is based on a standard hydride generation protocol. While field testing did not prove as accurate as laboratory tests it still has some value. Discussed are the arsine gas detector modification potential, methods to provide automated "on-line" monitoring and utilization for arsenic removal.

"Arsenic is one of the most toxic and carcinogenic elements in the environment. This book brings together the current knowledge on arsenic contamination worldwide, reviewing the field, highlighting common themes and pointing to key areas needing future research. Contributions discuss methods for accurate identification and quantification of individual arsenic species in a range of environmental and biological matrices and give an overview of the environmental chemistry of arsenic. Next, chapters deal with the dynamics of arsenic in groundwater and aspects of arsenic in soils and plants, including plant uptake studies, effects on crop quality and yield, and the corresponding food chain and human health issues associated with these exposure pathways. These concerns are coupled with the challenge to develop efficient, cost effective risk management and remediation strategies: recent technological advances are described and assessed, including the use of adsorbants, photo-oxidation, bioremediation and electrokinetic remediation.
