I recommend
Visit Sunny Chernobyl By Andrew Blackwell.
Website at
http://www.visitsunnychernobyl.com/
It's a sort of travelog, with the subtitle including "and other adventures in the world's most polluted places."
The places visited include, beside Chernobyl, the Alberta tarsands, the Texas oil refinery town of Port Arthur, the great Pacific Garbage patch, in Brazil, Santarem for Amazon deforestation, two areas in China for electronics recycling pollution and for coal mining effects, then "downstream on India's most polluted river."
I found Blackwell's book engrossing, reasonably informative and even funny in spots. He does present things from more than one angle, both from the traditional environmentalist viewpoint and also from the viewpoint of the people who actually live in these areas.
I checked it out from the local public library, definitely worth reading if you can borrow it. Not quite sure it's worth buying your own copy though.
