A Small Dose of Toxicology: The Health Effects of Common Chemicals



A Small Dose of Toxicology: The Health Effects of Common Chemicals, 2nd edition, by Steven G. Gilbert explores the principles of toxicology by examining the health effects of common chemical agents. Every day, we come into contact with many relatively harmless substances that could, at certain concentrations, be toxic. This applies not only to obvious candidates such as asbestos, lead, mercury, and gasoline, but also to such common compounds as caffeine, alcohol, nicotine, and headache tablets. While the field of toxicology has numerous technical books devoted to aspects of biology, chemistry, and mechanisms of action, A Small Dose of Toxicology places toxicology within the framework of our daily lives.  


This edition is available only as an e-book and contains numerous hyperlinks to articles and PowerPoint presentations on Toxipedia, as well as additional resources.

Below is the table of contents; the pages for individual chapters contain supplemental material including a chapter overview, pdf file of the chapter (the most up-to-date version is in the e-book), a PowerPoint file that can be used as an aid for teaching, and reference material with links. A Small Dose of Toxicology, 2nd edition, was posted on the ASmallDoseof.org website in early 2012 and represented a significant update to all book chapters as well as the addition of several new chapters.
