The next four chapters review the fundamentals of toxicology, including the dose-response relationship, metabolism of xenobiotics, toxicity testing, variations in individual responses and chemical carcinogenesis. These chapters give a succinct overview of toxicology, particularly from a biochemical perspective without going into a great detail on the underlying biology.
