Do you know where you heard that alcohol kills fish in small quantities?

On Mythbusters recently, they tested the myth that vodka makes a good bee 
killer.  A couple of their control bees in water died, but all the vodka 
bees survived.  I'm wondering if the fish story is similar.

Also, I can't think of anything in a pump made of refined and synthetic 
materials that would be harmful to humans and not fish.

Overall you're probably right just based on the legal requirements to make 
something suitable for humans.  They could use Pb solder in a fish pump but 
not a human pump for example.
