Exactly. It's called exposure and risk assessment. In my calculation the amount clothianidin would be 17,000 mg per acre. That's like one half of an ounce, but as pointed out that's enough to kill millions of bees. BUT the clothianidin isnt just dumped in a pile and a million bees proceed to ingest it. It's spread out over an acre of land and ends up at a low enough concentration that a bee would have to ingest an enormous amount of dirt (relative to a bee) to receive a toxic dose. Last time I checked, bees dont eat dirt.
If the route of exposure is claimed to be fugitive dust landing on nearby flowers, the clothianidin is even further diluted in the air, and then even further diluted as the pollen falls on a flower, and even further diluted as only a percentage of contaminated dust would stick to a pollen grain or incorporate into the flower nectar. The route of exposure may be complete, but the dose isnt there.
