Book Description
In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

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
This excellent volume was designed and edited with two major ideas in mind: firstly, the field of clinical toxicology is changing and an acknowledgement of these changes is warranted; secondly, no comprehensive compilation of recently published case reports of, and clinical studies on, human poisonings is available, which is in sharp contrast to the closely related field of drug-induced side-effects.The book focusses on issues of recent concern, or issues poorly documented in the past. It is important that clinical toxicologists gain a better knowledge of all the available techniques of toxicological analysis. A better understanding of the way a sound interpretation of results should be conducted for the benefit of the patient's management, and a comprehensive set of data on the kinetics of the most common pharmaceutical drugs and many chemicals is required.Human Toxicology is a timely reference work which will be welcomed by a broad audience of toxicology professionals.

Book Description
Richard Rudgley's first book, Essential Substances, was the winner of the British Museum Prometheus Award and hailed as a masterpiece by the Director of Harvard Botanical Museum. It is still one of the few books to have explored the role of drugs in the religious, political, economic and sexual life of our species from prehistory to the present day, covering a range of cultures as diverse as the Amazonian Indians, the Scythians of the ancient world and the witches of Medieval Europe alongside inner city crack and drugs in the counterculture. It is a magical tour of the bizarre world of intoxicants peopled by tribesmen and mystics, statesmen and writers, housewives and yuppies. Rudgley cogently shows how the significance of these substances extends beyond simple pleasure to the economic, political, and sexual life of a community. In the process, he challenges our assumptions that deem certain intoxicants socially and legally acceptable, while others remain taboo. Essential Substances remains a timely, much-needed reconsideration of the roles intoxicants play in our lives and society. Added for this edition is a new appendix, 'A Psychoactive Bestiary'. 'A splendid contribution to the new wave of scholarship that is forcing a different approach to our ages-old fascination with hallucinogenic plants and altered states. Richard Rudgley is to be congratulated' - Terence McKenna, author of Food of the Gods and True Hallucinations 'Should be required reading for all legislators who think disliked substances can be made to vanish by means of criminal sanctions' - Andrew Weil MD, author of The Natural Mind Richard Rudgley is a critically acclaimed author whose books have been translated into twelve languages. The author of several books, he has also written and presented several documentaries that have aired on Channel 4 in the United Kingdom and on various channels internationally. Arktos has also republished his books Wildest Dreams: An Anthology of Drug-Related Literature, which collects writings both ancient and modern describing the drug experience; and Barbarians, which is about the Dark Ages.

Book Description
Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.
