The Chemistry and Bacteriology of Public Health deals with public health hygiene. This book reviews the alkalimetry, acidimetry, standard solutions, normal solutions, and the preparation of solutions in public health laboratories, including methods of estimating equivalent weights of substances. In collecting water samples for analysis, the investigator should avoid all sources of extraneous contamination. The Wanklyn's process analyzes organic matter in the water: different tests give quantitative estimates of water contamination or bacterial purity. The authors point that the process of analyzing sewage and sewage effluents are the same as in water analysis except that sewage is diluted with distilled water. The authors also explain how air and water are analyzed, soil analysis being a complex process. The authors discuss milk analysis (fresh, boiled, skimmed, powdered, condensed), butter, cheese, food grains. Microscopic examination of bacteria from samples taken are examined alive, in film preparations, or in sections. The book describes in detail the different types of bacteria, their occurrence, and how these are examined or cultured. This book is intended as a laboratory handbook for students taking up the examination in Public Health. The book can also prove beneficial for social worker, public health officials, and for undergraduate medical students.

The presence of cyanide is a significant issue in industrial and municipal wastewater treatment and management, in remediation of former manufactured gas plant sites and aluminum production waste disposal sites, in treatment and management of residuals from hydrometallurgical gold mining, and in other industrial operations in which cyanide-bearing wastes were produced. The complexity of the chemistry and toxicology of cyanide and the risk it poses in different environmental contexts make its management and remediation extremely challenging. Cyanide in Water and Soil is the first book to present the state-of-the-art in managing cyanide across a wide range of industrial and environmental contexts. The book brings together current knowledge and information about cyanide release to and behavior in the environment, and explores how to control or remediate these releases. No other broad-based examination of this topic exists. Exploring the anthropogenic and natural sources of cyanide in the environment, the authors address the full range of issues pertaining to cyanide fate, transport, treatment, and toxicity in water and soil as well as approaches currently used in risk assessment and management. They have developed a careful balance of depth and scope of coverage, providing current references that help readers learn more about topics of particular interest. An array of technologies is available for the treatment of cyanide in surface water and groundwater, wastewaters, and contaminated soils and sludges. These technologies span the gamut of biological, chemical, electrolytic, physical, and thermal treatment processing. Presenting examples of applications of the technologies employed most commonly in municipal and industrial settings, the book is a useful reference tool for engineers, scientists, practitioners, and researchers in academia, industrial organizations, government, and engineering and science consulting firms.

Physicochemical and Environmental Plant Physiology provides an understanding of various areas of plant physiology in particular and physiology in general. Elementary chemistry, physics, and mathematics are used to explain and develop concepts. The first three chapters of the book describe water relations and ion transport for plant cells. The next three chapters cover the properties of light and its absorption; the features of chlorophyll and the accessory pigments for photosynthesis that allow plants to convert radiant energy from the sun into chemical energy; and how much energy is actually carried by the compounds ATP and NADPH. The last three chapters consider the various forms in which energy and matter enter and leave a plant as it interacts with its environment. These include the physical quantities involved in energy budget analysis; the resistances affecting the movement of both water vapor and carbon dioxide in leaves; and the movement of water from the soil through the plant to the atmosphere.

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

First published in 1988, this volume surveys the chemical synthesis and biological activity of the benz[a]anthracenes. These compounds occur in smoke and mineral oils and a few have been shown to be potent carcinogens. This volume was the first to review, systematically and in depth, the organic synthesis of these compounds as well as their metablolism, interactions with nucleic acids and protein, mutagenicity and carcinogenicity. Such studies have important implications in determining mechanism and specificity of chemically induced carcinogenesis.

The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1–10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.

The study of the environment requires the reliable and accurate measurement of extremely small quantities of chemicals and the ability to determine if they are pollutants or naturally occurring species. Historically, a "dilute and disperse" method of waste disposal has been accepted; yet as we learn the long-term consequences of such an approach, it is clear that more rigorous waste management techniques are necessary to understand the sources and fates of contaminants and to regulate their discharge. This volume presents the details of the basic analytical science involved in making these measurements. It concentrates on the basic principles of sampling and sample preparation, followed by the chemical principles of the major instrumental methods used in chemical analysis, and detailed discussions of the major environmental matrices. This book also provides coverage of topics usually only partially discussed in textbooks, such as quality assurance plans and statistical data handling. Students majoring in environmental sciences need a foundation in measurement techniques used in the field. Environmental Chemical Analysis gives students a thorough grounding in this field and enough information to judge the quality and interpret the information produced in the analytical laboratory.

The field of environmental chemistry has evolved significantly since the publication of the first edition of Environmental Chemistry. Throughout the book’s long life, it has chronicled emerging issues such as organochloride pesticides, detergent phosphates, stratospheric ozone depletion, the banning of chlorofluorocarbons, and greenhouse warming. During this time the first Nobel Prize for environmental chemistry was awarded. Written by environmental chemist Stanley Manahan, each edition has reflected the field’s shift of emphasis from pollution and its effects to its current emphasis on sustainability. What makes this book so enduring? Completely revised, this ninth edition retains the organizational structure that has made past editions so popular with students and professors while updating coverage of principles, tools, and techniques to provide fundamental understanding of environmental chemistry and its applications. It includes end-of chapter questions and problems, and a solutions manual is available upon qualifying course adoptions. Rather than immediately discussing specific environmental problems, Manahan systematically develops the concept of environmental chemistry so that when he covers specific pollutions problems the background necessary to understand the problem has already been developed. New in the Ninth Edition: revised discussion of sustainability and environmental science updates information on chemical fate and transport, cycles of matter examination of the connection between environmental chemistry and green chemistry coverage of transgenic crops the role of energy in sustainability potential use of toxic substances in terrorist attacks Manahan emphasizes the importance of the anthrosphere – that part of the environment made and operated by humans and their technologies. Acknowledging technology will be used to support humankind on the planet, it is important that the anthrosphere be designed and operated in a manner that is compatible with sustainability and that it interacts constructively with the other environmental spheres. With clear explanations, real-world examples, and updated questions and answers, the book emphases the concepts essential to the practice of environmental science, technology, and chemistry while introducing the newest innovations in the field. Readily adapted for classroom use, a solutions manual is available with qualifying course adoption.

The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. This tradition has been somewhat neglected since the introduc tion of mineral fertilizers at low cost. More and more farmers and scientists are now showing renewed interest in the proper and effective use of org~tnic residues, composts and other recycled organic additives. The role and function of organic amendments in modern agricultural systems have become topics of major interest in the scientific and agricultural communities. Research work on residue disposal has provided new concepts on the interaction between organic components and soils as well as new handling technologies (e. g. pelletizing of organic residues). The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods. The drive to achieve higher yields in commercial greenhouse farming has led to a search for optimum substrates as growth media and for improved management techniques. This has led to the introduction of organic substitutes for peat, nota bly those originating from agricultural wastes. Another important aspect is the current interest in organic farming, where use of synthetic chemicals is avoided or prohibited. An increasing percentage of the population in highly developed countries is willing to pay premium prices for food produced on soils where inorganic fertilizers and other agricultural chemicals have not been used.
