Five ppb of most pesticides in one gram of nectar is something like 10 to the 12th power of molecules or ten trillion molecules.  More molecules than a human has cells in his whole body.  Or almost as much as the US national debt in dollars.  Individual molecules are pretty small critters.

 So one molecule of IMI
 can potentially block one single synapse.  If that
 IMI molecule breaks down to a metabolite that
 retains the binding site the
 metabolite can
 block one single synapse but the parent IMI is now gone
 and
 no longer exists.  
 
 Okay,  help me out here,  I need to dumb it
 down again,   assuming with no
 doubt the above is correct,  One molecule, 
 is the same as One part?  So if
 I get a
 dose of say 5 ppb,  I block off 5 synapse?  Out of
 millions??  Why
 is that a huge problem?
