Query: Overpriced piece of junk

What a terrible book. I am currently taking an environmental chemistry course, and I'm learning more from my freshman Chem 101 notes and wikipedia than I am from this book. The chapters are too brief to even teach a topic, the examples aren't explained well, you have no idea what is truly going on because facts are simply thrown at you, and overall, this book makes you hate environmental chemistry.Additionally, the book is exorbitantly priced, as there are NO illustrations whatsoever and the inside looks like some cheap international edition - no color, maybe a scatter plot here and there. It is impossible to visualize any concepts that the book discusses. The authors are probably snoozing in their mansions right now as miserable students attempt to learn from this worthless piece of trash. DO NOT BUY THIS BOOK.
