is the EPA site where you can see all the pesticides that are out there 
and get the info on them, at least what they got from the manufacturer 
and/or other sources. They cite all the references they used for the data.

It is a good starting point, and then you can search the more green 
sites for the death and destruction that are 'actually" cause by the 
pesticide. You have to be fairly discerning with either, since there may 
not be good science, but the EPA is much less suspect with better 
reference support.

The best studies are usually field studies where measurements are real 
life, instead of laboratory. Even then, watch for agendas.
