This practical resource provides toxicologists and scientists with essential information on the regulations that govern their jobs and products. Regulatory Toxicology also covers the scientific and historical underpinnings of those regulations. Each chapter provides a grounding in the historical events that led to the development of original legislation and major subsequent changes in legislation. The major administrative divisions for regulatory agencies and their main missions and responsibilities are also detailed, as are the basic filing units or documents the agencies require of individuals to meet goals. This second edition is updated to reflect new developments in the field.
