NealStephenson novel about a professional asshole. Someone who makes a living harassing polluters, on behalf of an environmentalist group.

Generally portrays big business as ruthless and amoral. Rather CyberPunkish, without having a technological focus.
Different technical focus, but it is in there. The main character is a chemist by training and got pulled into the wonderful world of environmental activism by situations. I love how he explains why you can't trust chemicals more complex than alcohol.
