Toxicologists‚ the scientists who help determine the limits for safe use of materials‚ use modern technological research methods‚ including tests on animals‚ to protect human and animal health and the environment. What is toxicology? Toxicology is the study of how chemical substances interact with living systems and affect normal processes‚ and the use of this information to predict safe exposure levels. Toxicological research and testing helps us to live safely and to derive benefit
