They support life. They make it beautiful and fun. They allow us to live and maintain the so- called good life. This book points out, however, that as wonderful as they are . . . they can also make some people sick, and damage plants and animals—the environment in which we live. This book is a comprehensive treatment of a very broad field. The chapters are timely and factual, well balanced, referenced, and written in plain English for general readers, college students, environmental health practitioners, lawyers, public administrators, utility directors (water and wastewater treat- ment), public service managers, non-environmental managers, regulators, and non-environmental health professionals in any field who desire to obtain understanding of everyday environmental health issues. Also, this book examines health issues, scientific understanding of causes, and possible future approaches to control the major environmental problems in industrialized and developing countries. This book offers an overview of the methodology and paradigms of the dynamic, evolving field, ranging from ecology (environment and aquatic and terrestrial) to epidemiology, from environmental psychology to toxicology, and from genetics to ethics. Topics include how the body reacts to environmental pollutants and stressors, and they cover the many effects of environmental factors: physical, chemical, and biological agents of environmental contamination; vectors for dissemination (air, water, soil); solid and hazardous waste; susceptible populations; bio- — vii — BBooookk 11..iinnddbb vviiii 11//3300//1133 1100::5566 AAMM viii Preface markers and risk analysis; the scientific basis for policy decision; occupational health and safety issues; and emerging global environmental problems. Moreover, this book not only covers the environmental sciences but also the human population. It emphasizes the environmental practices that sup- port human life as well as the need to control factors that are harmful to human life. With chapters providing a judicious use of figures and tables, each sector includes an appropriate amount of material for an overview of the topics presented. The bottom line is that this book is not just a book; it is a handbook. While it can be used anywhere—in the library, in the c lassroom, in the office, and/ or in the laboratory—it is designed to be used primarily in the field. It is designed to be a “handheld” reference and guide providing guidelines about environmental health and how to maintain it in the environmental world. Frank R. Spellman and Melissa L. Stoudt The real problem is the shock of severe, dangerous illness, its unexpected- ness and surprise. Most of us, patients and doctors alike, can ride almost all the way through life with no experience of real peril and when it does come, it seems an outrage, a piece of unfairness. We are not used to disease as we used to be, and we are not at all used to being incorporated into a high technology. —Lewis Thomas (1983), The Youngest Science BBooookk 11..iinnddbb vviiiiii 11//3300//1133 1100::5566 AAMM Prologue On Tuesday afternoon, a fifty-two-year-old man with previously di- agnosed coronary artery disease controlled by nitroglycerin describes episodes of recurring headache for the past three weeks. Mild nausea often accompanies the headache; there is no vomiting. He describes a dull frontal ache that is not relieved by aspirin. The patient states that the headaches are sometimes severe; at other times they are a nagging annoyance. The durations ran from half an hour to a full day. His visit was also prompted by a mild angina attack that he suffered this past weekend shortly after he awoke on Sunday morning. He has experienced no further cardiac symptoms since that episode. History of previous illness indicates that the patient was diagnosed with angina pectoris three years ago. He has been taking 0.4 milligrams (mg) ni- troglycerin sublingually (placed beneath the tongue) prophylactically before vigorous exercise. He also takes one aspirin every other day. He has been symptom-free for the past two and a half years. Sublingual nitroglycerin relieved the pain of the Sunday morning angina attack within several minutes. The patient does not smoke and rarely drinks alcohol. He is a trim man with a slightly ruddy complexion. Information in this chapter from CDC-ATSDR, Case Studies in Environmental Medicine.
