The Principles of Toxicology: Environmental and Industrial Applications 2nd Edition

The Principles of Toxicology: Environmental and Industrial Applications 2nd EditionA fully updated and expanded edition of the bestselling guide on toxicology and its practical application. The field of toxicology has grown enormously since Industrial Toxicology: Safety and Health Applications in the Workplace was first published in 1985. And while the original edition was hugely popular among occupational health professionals, the time is ripe to address toxic agents not only in the industrial setting but also in the environment at large.

The Principles of Toxicology: Environmental and Industrial Applications 2nd Edition

1 General Principles of Toxicology

GENERAL PRINCIPLES OF TOXICOLOGY ROBERT C. JAMES, STEPHEN M. ROBERTS, and PHILLIP L. WILLIAMS

The intent of this chapter is to provide a concise description of the basic principles of toxicology and to illustrate how these principles are used to make reasonable judgments about the potential health hazards and the risks associated with chemical exposures. This chapter explains
• Some basic definitions and terminology
• What toxicologists study, the scientific disciplines they draw upon, and specialized areas of
interest within toxicology
• Descriptive toxicology and the use of animal studies as the primary basis for hazard
identification, the importance of dose, and the generation of dose–response relationships
• How dose–response data might be used to assess safety or risk
• Factors that might alter a chemical’s toxicity or the dose–response relationship
• The basic methods for extrapolating dose–response data when developing exposure guidelines of public health interest

1.1 BASIC DEFINITIONS AND TERMINOLOGY

The literal meaning of the term toxicology is “the study of poisons.” The root word toxic entered the English language around 1655 from the Late Latin word toxicus (which meant poisonous), itself derived from toxikón, an ancient Greek term for poisons into which arrows were dipped. The early history of toxicology focused on the understanding and uses of different poisons, and even today most people tend to think of poisons as a deadly potion that when ingested causes almost immediate harm or death.

As toxicology has evolved into a modern science, however, it has expanded to encompass all forms of adverse health effects that substances might produce, not just acutely harmful or lethal effects. The following definitions reflect this expanded scope of the science of toxicology:

  • Toxic—having the characteristic of producing an undesirable or adverse health effect.
  • Toxicity—any toxic (adverse) effect that a chemical or physical agent might produce within a living organism.
  • Toxicology—the science that deals with the study of the adverse effects (toxicities) chemicals or
    physical agents may produce in living organisms under specific conditions of exposure. It is
    a science that attempts to qualitatively identify all the hazards (i.e., organ toxicities) associated
    with a substance, as well as to quantitatively determine the exposure conditions under which
    those hazards/toxicities are induced. Toxicology is the science that experimentally investigates
    the occurrence, nature, incidence, mechanism, and risk factors for the adverse effects of toxic
    substances….
