Focusing primarily on basic principles and concepts, Toxicology also provides 200 tables worth of toxicological data. Each heavily illustrated chapter is a complete study unit containing a table of contents, an introduction, a learning core, a self-test, and feedback. The main text for the unit is followed by a self-test, which reveals whether the learning objectives have been met. The feedback section answers frequently asked questions, while a summary enables the student to review the main concepts before moving on to the next unit.
