We're discussing chloramphenicol, but consider this:

Right now, as I understand this, the concentration of imidacloprid below
which no harm to bees is proven is considered to be about 20 ppb and
beekeepers want to reduce this to 6 or so.

What we have to ask ourselves is this: if -- as many maintain -- 6 ppb
of imidacloprid (or 20 ppb) is harmful to known organisms, then is 5.46
ppb of another man-made molecule necessarily a harmless amount?

Of course the two substances are not comparable in many (most)? aspects,
but AFAIK, neither occurs in nature.
