The principles and practice of toxicology have contributed to protecting not only the individual at work or at home, but populations, communities, and our delicate terrestrial and aquatic environments as well. Toxicology: Principles and Practice in Public Health is the ideal text for a first course in toxicology for the public health student. In five sections, it offers an introduction to the field, as well as the basics of toxicology principles, chemical toxicity, ecotoxicology, and toxicology practice. The text is immediately readable for the student with little technical background.
