Re: Cancer ahoy
When it comes to lovely chemicals I'd highly recommend the "stuff I won't work with" series bij Derek Lowe; http://blogs.sciencemag.org/pipeline/archives/category/things-i-wont-work-with
Start with: "Sand won't save you this time" http://blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time
Highly entertaining stuff, even for those of us with no background in chemicals. If you've had basic high-school level chemistry lessons you'll understand enough for it to be highly cringe/laughter inducing.
