Bees use water sources which could contain weed killers.
What´s the result to their health? Any research links available?

SiWolke: I was just listening to a podcast this week with Jon Zawislak of the University of Arkansas. Jon has just finished a study where he did pollen collections every two weeks from hives sites in agricultural areas vs. hive sites in urban areas in Arkansas. He briefly talked about the various herbicides he picked up, noting that he suprisingly found no glyophosate. The podcast is "Hive Talk" and it is the latest episode. I doubt Jon has had time to publish his findings yet, but I look forward to reading it. Not sure if this is the type of thing you are looking for.
