Book Description
Environmentalists often voice concern about threats like acid rain, carbon dioxide buildup in the atmosphere, water contamination, and declining biodiversity. Recently, many have come to recognize another equally serious threat called biological pollution. Biological pollution is the movement of living organisms, either accidentally or intentionally, from the places where they evolved to new environments where a lack of natural enemies permits their population to explode. These organisms, sometimes called invasive exotic pests, threaten our crops, our forests, and perhaps even our very existence. Biological pollutants, like chemical pollutants, are here because of human activities. But unlike chemical pollutants, biological pollutants cannot be reduced or prevented by legislation. Once biological pollutants are imported, they grow, adapt, multiply and spread on their own unless direct, vigorous, and often costly actions are taken to stop them.Written by biological scientists participating in a meeting sponsored by the Forest Pathology Committee of The American Phytopathological Society (APS), Biological Pollution: An Emerging Global Menace presents a broad spectrum of concerns in nontechnical language to conservation-minded people. The first three chapters provide general background on biological pollution, including insight into the enormity of the problem and the direct and indirect costs to date. The next section provides specific examples of exotic weeds, diseases, nematodes, and insects and the damage they cause. The last section examines the defenses in place and proposed improvements to resisting biotic invasion. Biological Pollution: An Emerging Global Menace is required reading for environmentalists, plant pathologists, horticulturists, weed scientists, nematologists, entomologists, foresters, agronomists and all others dedicated to protecting the environment. Anyone interested in natural resources and agriculture will gain valuable knowledge from this eye-opening publication.ContentsPreface; What Is the Problem?: Controlling Biological Pollution; An Ecological Explosion in Slow Motion; Exotic Pests: past, present and future; Weeds, Diseases, and Other Pests: Exotic Weeds: Expensive and Out of Control; Plant Disease On The Move!; Plant-Parasitic Nematodes Which Are Exotic Pests in Agriculture and Forestry; What Is to be Done?: Meeting the Threat: Risk Assessment and Quarantine; Assessing Exotic Threats to Forest Resources; Political and Economic Barriers to Scientifically-Based Decisions; Fighting Back

Book Description
The preface of a book often provides a convenient place in which the author can tender his apologies for any inadequacies and affords him the facility to excuse himself by reminding the reader that his art is long but life, or at least the portion of it in which he has the opportunity for writing books, is short. I, too, am deeply conscious that I have undertaken a task which I could not hope to complete to my own satisfaction but I offer, in self defence, the observation that, inadequate though it is, there is no other book extant, so far as I am aware, which provides the information contained herein within the covers of a single volume. Often during the last decade, in discharging my responsibilities for the environmental aspects of the water authority's operations and works, I should have been deeply grateful to have had access to a compendium such as this. The lack of a convenient source of data made me aware of the need which I have attempted to fill and in doing so I have drawn on my experiences of the kinds of problem which are presented to biologists in the water industry. The maxim 'half a loaf is better than none' seems particularly apt in this context.

Book Description
In the past two decades there has been an increasing public awareness of the hazards that exist from the contamination of the environment by toxic substances. 'Heavy metals' and the terrestrial environment are but one facet of the impact of toxic substances on the natural environment, and the use of biological materials for indicating the occurrence of, and continually monitoring the presence of, these materials is a specific topic which is of considerable interest to a diverse range of individuals, organisations and disciplines. It was our intention when we first en visaged this book that it should contain a description of a range of circumstances in which biological monitoring techniques have been employed in the terrestrial environment and that it should be seen as a practical text which dealt with the merits, shortcomings and suitability of biological monitoring materials. Monitoring is, however, a manifold process. It serves not only to provide information on past and present concentrations of toxic materials in various components of the environ ment, but also to provide information on the processes of environmental release, transport, accumulation and toxicity. Indeed, this may be one of the greatest virtues of biological monitoring over other forms of monitor ing. According to the skill of the staff employed in the monitoring procedure, the information that is accrued can have a vastly different value.

Book Description
More than 50 million Americans, one out of five, suffer from hay fever, asthma, and other allergic diseases. Many of these conditions are caused by exposure to allergens in indoor environments such as the house, work, and schoolâ€"where we spend as much as 98 percent of our time. Developed by medical, public health, and engineering professionals working together, this unique volume summarizes what is known about indoor allergens, how they affect human health, the magnitude of their effect on various populations, and how they can be controlled. The book addresses controversies, recommends research directions, and suggests how to assist and educate allergy patients, as well as professionals. Indoor Allergens presents a wealth of information about common indoor allergens and their varying effects, from significant hay fever to life-threatening asthma. The volume discusses sources of allergens, from fungi and dust mites to allergenic chemicals, plants, and animals, and examines practical measures for their control. Indoor Allergens discusses how the human airway and immune system respond to inhaled allergens and assesses patient testing methods, covering the importance of the patient's medical history and outlining procedures and approaches to interpretation for skin tests, in vitro diagnostic tests, and tests of patients' pulmonary function. This comprehensive and practical volume will be important to allergists and other health care providers; public health professionals; specialists in building design, construction, and maintenance; faculty and students in public health; and interested allergy patients.

Book Description
Microbial pollution is a key element of indoor air pollution. It is caused by hundreds of species of bacteria and fungi, in particular filamentous fungi (mould), growing indoors when sufficient moisture is available. This document provides a comprehensive review of the scientific evidence on health problems associated with building moisture and biological agents. The review concludes that the most important effects are increased prevalences of respiratory symptoms, allergies and asthma as well as perturbation of the immunological system. The document also summarizes the available information on the conditions that determine the presence of mould and measures to control their growth indoors. WHO guidelines for protecting public health are formulated on the basis of the review. The most important means for avoiding adverse health effects is the prevention (or minimization) of persistent dampness and microbial growth on interior surfaces and in building structures. [Ed.]

Book Description
Human survival depends on the availability of clean air, water, and food and on the welfare of plants and animals. However, anthropogenic and naturally occurring chemicals can cause adverse effects on living organisms and ecological processes. Environmental Toxicology: Biological and Health Effects of Pollutants, Third Edition presents fundamental
