Elaborate apparatus plays an important part in the science of to-day, but I sometimes wonder if we are not inclined to forget that the most important instrument in research must always be the mind of man. It is true that much time and effort is devoted to training and equipping the scientist's mind, but little attention is paid to the technicalities of making the best use of it. There is no satisfactory book which systematises the knowledge available on the practice and mental skills—the art—of scientific investigation. This lack has prompted me to write a book to serve as an introduction to research. My small contribution to the literature of a complex and difficult topic is meant in the first place for the student about to engage in research, but I hope that it may also interest a wider audience. Since my own experience of research has been acquired in the study of infectious diseases, I have written primarily for the student of that field. But nearly all the book is equally applicable to any other branch of experimental biology and much of it to any branch of science. – (Cambridge, 1957. W.I.B. Beveridge)

Chemistry: The Molecules of Life is the only textbook for non-majors that focuses on the fundamental chemistry of biological molecules and everyday life. It uses the chemistry of life to introduce, explain, and apply chemical principles. Each chapter begins with a framing question to stimulatestudents' interest. Many framing questions are pertinent to students' health, whereas others address foundational scientific topics. Scientific content in each chapter is introduced on a "need-to-know" basis that is related to the framing question. By the end of the chapter, students will be able toanswer the question using the chemical concepts they have learned.Chemistry: The Molecules of Life is designed for students who have a variety of academic and career interests, not all of which necessarily align with the sciences or health professions. Its authors believe that all undergraduate students - not just science majors - need to be educated aboutscientific knowledge and reasoning in order to make informed decisions about their personal well-being and important societal issues. Have you ever thought about how antibiotic medications work, or why it is important to take the entire dose that the doctor prescribed? Many of us also take a vitaminsupplement, often in the form of a daily multivitamin. Do you know what roles these vitamins play in our body, or why the recommended daily dose for some vitamins is much lower than for others? Does the federal government regulate vitamin supplements with the same scrutiny that it applies topharmaceuticals? Chemistry: The Molecules of Life examines relevant topics such as these and many more.Scientific knowledge is constantly advancing. Almost daily, the media reports on a new scientific discovery, a new interpretation of what foods or activities are good or bad for us, or the societal impact of a new medical breakthrough. Given this rapid progress, science cannot be presented as acollection of facts to be memorized. After a short time, even the most current scientific knowledge becomes outdated. Instead, students need to understand how scientists investigate the natural world-the methods they use, the evidence they generate, and the conclusions they make based on thatevidence. For this reason, each chapter of Chemistry: The Molecules of Life describes examples of scientific discovery. By analyzing these case studies, students will develop the critical thinking skills necessary to thoughtfully evaluate scientific information that is presented in the news media orobtained from other sources.

Including findings from experimental as well as clinical studies, this one-of-a-kind handbook is prepared in a very user- friendly format that can easily be followed by students, teachers and researchers, as well as lay people. Stand-alone chapters on individual chemicals and major topics allow the reader to easily access required information without searching through the entire book. This is the first book that offers in-depth coverage of individual toxicants, target organ toxicity, major incidents, toxic effects in humans, animals and wildlife, biosensors, biomarkers, on-site and laboratory analytical methods, decontamination and detoxification procedures, prophylactic, therapeutic and countermeasures, and the role of homeland security. Presents a comprehensive look at all aspects of chemical warfare toxicology in one reference work. This saves researchers time in quickly accessing the very latest definitive details on toxicity of specific agents used in chemical warfare as opposed to searching through thousands of journal articles. Will include the most agent-specific information on the market Includes detailed coverage of the most exhaustive list of agents possibly used as chemical warfare agents in one source. Section 4: Agents That Can Be Used as Weapons of Mass Destruction ? 25 chapters long. Other books on the market only include a sample selection of specific agents. Offering all possible agents detailed under one cover makes this appealing to a wider audience and saves researchers time The Forward will be written by Dr. Tetsuo Satoh, Chiba University, Japan. He is one of the most respected, recognizable authorities on chemical warfare agents which will set the authoritative tone for the book Covers risk to humans, animals and the environment equally. Researchers involved in assessing the risks involved with a possible chemical warfare attack and those who are developing response plans to such attacks must look at not only the risks to human health but to our wildlife and environment as well. The holistic approach taken in this book ensures that the researchers have ready access to the details no matter which aspect of the effects of CWA's they might be concerned with

Published more than three decades after Rachel Carson's Silent Spring warned of the impact of chemicals on the environment, this book offers a critique of current thinking on cancer and its causes. It argues that the evidence has been wilfully ignored, and that the environment is still being poisoned. Throughout her study, the author weaves two stories - of Rachel Carson and her battle to be heard and of her own cancer of the bladder, which she traces back to agricultural and industrial contamination.

Study and Interpretation of the Chemical Characteristics of Natural Water

The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from activities of man. Some of the processes of solution or precipitation of minerals can be closely evaluated by means of principles of chemical equilibrium including the law of mass action and the Nernst equation. Other processes are irreversible and require consideration of reaction mechanisms and rates. The chemical composition of the crustal rocks of the earth and the composition of the ocean and the atmosphere are significant in evaluating sources of solutes in natural fresh water. The ways in which solutes are taken up or precipitated and the amounts present in solution are influenced by many environmental factors, especially climate, structure and position of rock strata, and biochemical effects associated with life cycles of plants and animals, both microscopic and macroscopic. Taken all together and in application with the further influence of the general circulation of all water in the hydrologic cycle, the chemical principles and environmental factors form a basis for the developing science of natural-water chemistry. Fundamental data used in the determination of water quality are obtained by the chemical analysis of water samples in the laboratory or onsite sensing of chemical properties in the field. Sampling is complicated by changes in composition of moving water and the effects of particulate suspended material. Most of the constituents determined are reported in gravimetric units, usually milligrams per liter or milliequivalents per liter. More than 60 constituents and properties are included in water analyses frequently enough to provide a basis for consideration of the sources from which each is generally derived, most probable forms of elements and ions in solution, solubility controls, expected concentration ranges and other chemical factors. Concentrations of elements that are commonly present in amounts less than a few tens of micrograms per liter cannot always be easily explained, but present information suggests many are controlled by solubility of hydroxide or carbonate or by sorption on solid particles. Chemical analyses may be grouped and statistically evaluated by averages, frequency distributions, or ion correlations to summarize large volumes of data. Graphing of analyses or of groups of analyses aids in showing chemical relationships among waters, probable sources of solutes, areal water-quality regimen, and water-resources evaluation. Graphs may show water type based on chemical composition, relationships among ions, or groups of ions in individual waters or many waters considered simultaneously. The relationships of water quality to hydrologic parameters, such as stream discharge rate or ground-water flow patterns, can be shown by mathematical equations, graphs, and maps. About 75 water analyses selected from the literature are tabulated to illustrate the relationships described, and some of these, along with many others that are not tabulated, are also utilized in demonstrating graphing and mapping techniques. Relationships of water composition to source rock type are illustrated by graphs of some of the tabulated analyses. Activities of man maymodify water composition extensively through direct effects of pollution and indirect results of water development, such as intrusion of sea water in ground-water aquifiers. Water-quality standards for domestic, agricultural, and industrial use have been published by various agencies. Irrigation project requirements for water quality are particularly intricate. Fundamental knowledge of processes that control natural water composition is required for rational management of water quality.
