Dramatic changes in the field of environmental health since the Third Edition was published in 2004 demand a new, radically updated version of this essential textbook.Based on the recommendations of advisory bodies and federal agency regulations, as well as a thorough review of the scientific literature, Moeller’s Fourth Edition is the only fully current text in this burgeoning field. It features new tables and figures, and revisions of those retained from previous editions. Environmental Health is also enriched with the knowledge and insights of professionals who are deeply involved in “real world” aspects of each subject covered.In eighteen chapters, students receive a complete but manageable introduction to the complex nature of the environment, how humans interact with it, and the mutual impact between people and the environments where they work or live. This new edition emphasizes the challenges students will face in the field: the local and global implications of environmental health initiatives, their short- and long-range effects, their importance to both developing and developed nations, and the roles individuals can play in helping to resolve these problems.Whether discussing toxicology, injury prevention, risk assessment, and ionizing and non-ionizing radiation, or more traditional subjects like the management and control of air, water, and food, Dade Moeller emphasizes the need for a systems approach to analyzing new projects prior to their construction and operation.Environmental Health is indispensable reading for practitioners, students, and anyone considering a career in public health.
