Here's a good article on how pesticides accumulate in pollen. The
authors don't claim to understand how the pesticides may impact the
bees, but report on how much they're finding.There's another article
from J. Econ. Ent. that talks about solitary bee foraging.

Interesting article, but I'd like to see the peer-reviewed
research. Nearly every statement in the article contains "weazel"
words or wording that implies uncertainty (e.g., "which SUGGESTED
the sprays were toxic," "the solutions COULD be more toxic," etc.).
Very few of the ideas in the article come across as proven facts,
although that might reflect the writing style of the author.
I've become a bit skeptical of popular articles about bee
problems because, in the barrage of early articles on Colony
Collapse Disorder, beekeepers almost always blamed pesticides
whereas later research either vindicated pesticides or listed them
as only one among many contributing factors.
Came across this article this morning and thought it quite
interesting.
