Book Description
Over the last century, the industrialization of agriculture and processing technologies have made food abundant and relatively inexpensive for much of the world’s population. Simultaneously, pesticides, nitrates, and other technological innovations intended to improve the food supply’s productivity and safety have generated new, often poorly understood risks for consumers and the environment. From the proliferation of synthetic additives to the threat posed by antibiotic-resistant bacteria, the chapters in Risk on the Table zero in on key historical cases in North America and Europe that illuminate the history of food safety, highlighting the powerful tensions that exists among scientific understandings of risk, policymakers’ decisions, and cultural notions of “pure” food.

Book Description
Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book Description
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.

Book Description
This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.

Book Description
Sex, drugs, rocks, gold, murder, war, mass poisonings, the deaths of Napoleon, Tchaikovsky, Mozart, and others are all linked by one element - arsenic! Arsenic has been around since the beginning of time and the word has become a metaphor for poison with associated shock value. The general public are fearful of any possible exposure to it and yet it holds a certain dark and eerie fascination! The average person has only one idea about arsenic - it is poison - and this reputation has a sound base. Some arsenic compounds are very toxic and have been used with criminal intent from the time of the ancient Romans to the present day. Up until now, there has been no book that covers arsenic with such breadth. This book is a general appreciation of how much the element, arsenic, has become part of our lives in an entertaining style covering the years 1000 BC to the present day. The coverage of the chemistry, toxicology, and medicinal aspects is deliberately kept at a level for the general reader to understand. It covers the way in which this ubiquitous element and its compounds have influenced the lives of the people of the world. The author's objective in writing this book was not to elaborate on the vast chemistry of the element, but to try to reveal to the general reader how the element and its compounds have become embedded in our social fabric, for good and for ill. No other element comes close in this regard and he uses the word sociochemistry to describe this interface between society and chemistry. The book covers a broad range of topics including the use of arsenic in human medicine in many cultures from Chinese medicine to the beginning of chemotherapy. This peaked in the western world in the early 20th century, with Ehrlich's discovery of salvarsan, an arsenic-based cure for syphilis that gave rise to the field of chemotherapy. Salvarsan and related compounds were eventually displaced by antibiotics such as penicillin. Arsenic trioxide has staged a comeback, however, and is being used as a successful treatment for a form of leukemia. Other chapters cover arsenic compounds which were widely used in agriculture and wood preservation during the 20th century and their associated myths as well as arsenic compounds as chemical warfare agents and the resulting stockpile. The topic of arsenic in the environment is discussed in depth - arsenic is all around us - in our soil, our water, and our food, and our bodies have adapted to its presence and it does not usually pose a problem. However, the natural presence of high concentrations of arsenic in drinking water currently threatens the lives of millions of people in India, Bangladesh, Mexico and elsewhere. It also covers mining and pesticide manufacturing which can lead to high local arsenic concentrations in soils, slag heaps and mine tailings which, when located close to human activities, can produce human health risks. Other chapters cover a variety of topics including: " A proposed connection between arsenic and Cot Death (SIDS) which caused panic " The high concentration of arsenic in kelp products-is this harmful? " What about the 237,000 tonnes of arsenic trioxide stored in a mine in Canada? " How toxic is arsenic anyway, and how do you assess the risks of exposure? " How did Napoleon die? These and many other topics are addressed at a level that will result in understanding without delving into too much technical detail or requiring a degree in chemistry. Essential reading for everyone with a general interest in science, this illuminating text covers a broad range of topics.
