There is actually a book on this now that I found in my local book store.  
It's called something along the lines of Eco-friendly house plants, and goes 
over about 50 species of houseplant, in addition to going over some of the 
theory behind it.  Unfortuneatly I gave the book to my Dad for Christmas, so I 
can't give the reference.  If you can find it, it seems like a really 
interesting book.
