2 ppb is about the concentration of imidacloprid that was found in both
pollen and nectar from canola grown one year after a field had been soil
injected for potatoes.
about 6 ppb is what Cynthia Scott Dupree was finding in the Ontario study
that was used to register imidacloprid as a seed treatment for canola.
about 8 ppb is what was found in sunflowers in France that were seed
treated.
