They have been shown again and again to avoid high concentrations of
neonics in nectar.  It is the lower concentrations that are above the NOAEL
but below the repellent level that may be a problem.

As far as toxic pollen, bees in many, but not all, areas avoid corn and
sunflower pollen, instead preferring other pollens.

In a recent survey in a Calif coastal town, which has been suffering very
high losses of bees, pollens were collected and analyzed.  Neonics did not
appear to be the issue.  I'll ask this weekend if the study will be
published.
