" One molecule, is the same as One part? So if I get a dose of say 5 ppb, I block off 5 synapse?" 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. Dick " Any discovery made by the human mind can be explained in its essentials to the curious learner." Professor Benjamin Schumacher talking about teaching quantum mechanics to non scientists.

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? Charles *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
