Molecular and Biochemical Toxicology 4th Edition

I am using this for a graduate level course. It is well written for a textbook. There's a lot of content. It's not that bad to carry around. It is printed on crisp white pages. You can highlight easily or write in pencil on the pages. The ink doesn't run off. It has general information about a variety of toxicology techniques and principles. I find it useful as a supplement to my lectures. It could be improved with the use of more colloquial language. However, if you want a reference book, many professors seem to recommend this. I find the price pretty reasonable for a textbook.
