Query: Great overview of Environmental Health

When I took "Environmental and Occupational Health" (EOH) for my master's in public health, this book provided the background for learning this broad course in a matter of 3 months. If I did not have this book while taking the EOH class, I would not have gotten an A. If you want an A in EOH, you should use this book.
