This sweeping history reveals how the use of chemicals has saved lives, destroyed species, and radically changed our planet: “Remarkable . . . highly recommended.” —Choice In The Chemical Age, ecologist Frank A. von Hippel explores humanity’s long and uneasy coexistence with pests, and how the battles to exterminate them have shaped our modern world. He also tells the captivating story of the scientists who waged war on famine and disease with chemistry. Beginning with the potato blight tragedy of the 1840s, which led scientists on an urgent mission to prevent famine using pesticides, von Hippel traces the history of pesticide use to the 1960s, when Rachel Carson’s Silent Spring revealed that those same chemicals were insidiously damaging our health and driving species toward extinction. Telling the story in vivid detail, von Hippel showcases the thrills—and complex consequences—of scientific discovery. He describes the creation of chemicals used to kill pests—and people. And, finally, he shows how scientists turned those wartime chemicals on the landscape at a massive scale, prompting the vital environmental movement that continues today.

Age Determination of Young Rocks and Artifacts by Günther A. Wagner Pdf
Dating the Quaternary, which covers approximately the last 2 million years, has experienced considerable progress over the past few decades. On the one hand, this resulted from the necessity to obtain a valid age concept for this period which had seen tremendous environmental changes and the advent of the genus Homo. On the other hand, instrumental improvements, such as the introduction of highly sensitive analytical techniques, gave rise to physical and chemical innovations in the field of dating. This rapid methodological development is still in full progress. The broad spectrum of chronometric methods applicable to young rocks and artifacts also becomes increasingly intricate to the specialist. Hence, it is my goal to present a comprehensive, state-of-the-art sum mary of these methods. This book is essentially designed as an aid for scientists who feel a demand for dating tasks falling into this period, i. e., Quaternary geologists and archaeologists in the broadest sense. Since it has been developed from a course of lectures for students of geological and archaeological sciences, held at the University of Heidelberg, it certainly shall serve as an introduction for students of these disciplines.
The Chemical Age - Chemical Dictionary - Chemical Terms. by Hesperides Pdf
Text extracted from opening pages of book: THE CHEMICAL AGE CHEMICAL DICTIONARY CHEMICAL TERMS LONDON: ERNEST BENN LIMITED 8, BOUVERIE STREET, B. C. 4 i 924 Print, d by Jarrold & Sons, Limited, Norwich PREFACE Y HE vast output of chemical literature at the present time is presenting almost insuperable I difficulties to those who attempt to keep abreast of the rapid advances in chemical science. Not the least of these difficulties is the terminology of the subject, for chemical terms are multiplying at a bewildering rate. Frequently, too, when a new word or expression is coined it is followed up with an abbreviation or symbol by which it is expressed. One has, in fact, only to glance through the abstracts of the English and American Chemical Societies to realise the difficulty. The Chemical Age Dictionary of Chemical Terms has been compiled by experts to meet the needs of all those who have to consult not only original papers or their abstracts but other forms of lit erature as represented by reviews and modern textbooks. It will, therefore, make a direct appeal to all chemists from the student to the director of research. The subjects dealt with include organic, inorganic, physical, analytical and biochemistry. Unfortunately, many chemical terms are loose and even vague and it is very difficult, if not impossible, to give exact definitions in such cases. Indeed, it is undesirable to attempt to give an exact definition where none exists This is especially the case with names by which certain theories or concepts are known. In general the terms will be found in the form in which they are most frequently met with in technical literature, but in order to avoid repetition it has been foundconvenient in some cases to include a number of closely related terms under one general term. Thus, the different types of isomerism are classed together under Isomerism, the different kinds of spectra under Spectrum, and so on. Tide many laws, reactions, etc., are not grouped together under these headings but will be found under the names by which they arc known For example Henry's Law, and not Law of Henry, Hoesch Reaction, and not Reaction, Hoesch van't Hoff factor and not Factor, van't Hoff. In many cases cross-references are given not only to the same subject but to cognate subjects. No effort has been spared to illustrate the explanations and definitions by means of examples; and it is hoped that these will be of great assistance in elucidating terms which could not otherwise be made perfectly clear. The Dictionary is an essential supplement to, but not a substitute for, the textbook. The present dictionary is intended to be the forerunner of successive volumes, each one of which will deal with the subject as it appears in its different phases. Thus, it is hoped to publish a second volume dealing with Organic Substances, a third dealing with Inorganic Substances, etc. No Dictionary compiled on similar lines has as yet appeared in the English language. It is hoped, therefore, that the present volume will prove not only a novelty, but an indispensable companion for all those who are interested in pure chemistry or its application to industry.

Now recognized as one of the most influential books of the twentieth century, Silent Spring exposed the destruction of wildlife through the widespread use of pesticides Rachel Carson's Silent Spring alerted a large audience to the environmental and human dangers of pesticides, spurring revolutionary changes in the laws affecting our air, land, and water. Despite condemnation in the press and heavy-handed attempts by the chemical industry to ban the book, Carson succeeded in creating a new public awareness of the environment which led to changes in government and inspired the ecological movement. It is thanks to this book, and the help of many environmentalists, that harmful pesticides such as DDT were banned from use in the US and countries around the world. This Penguin Modern Classics edition includes an introduction by Lord Shackleton, a preface by World Wildlife Fund founder Julian Huxley, and an afterword by Carson's biographer Linda Lear.
This open access book explores how young people engage with chemical substances in their everyday lives. It builds upon and supplements a large body of literature on young people’s use of drugs and alcohol to highlight the subjectivities and socialities that chemical use enables across diverse socio-cultural settings, illustrating how young people seek to avoid harm, while harnessing the beneficial effects of chemical use. The book is based on multi-sited anthropological research in Southeast Asia, Europe and the US, and presents insights from collaborative and contrasting analysis. Hardon brings new perspectives to debates across drug policy studies, pharmaceutical cultures and regulation, science and technology studies, and youth and precarity in post-industrial societies.

Absolute Age Determination by Mebus A. Geyh,Helmut Schleicher Pdf
The spectrum of physical and chemical dating methods now covers the entire range of Earth history. But there are so many methods that it is becoming increasingly difficult to select those that are appropriate for solving a specific problem. The objective of this book is to cover the whole spectrum of methods and to give examples of their applications. Thus it is addressed to everybody interested in the application of physical and chemical dating methods to the geosciences and archeology. It is especially valuable as a concise, but comprehensive reference for students and practitioners.
