Metals, such as selenium, I believe, and organic chemicals (e.g., PCBs) may be picked up by foraging honey bees and incorporated into honey and wax, and probaably (in the case of the organics) into fatty tissues in the bees themselves. Roger Morse and some others at Cornell have done some work in this area. I'll try to dig out specific references. Tom ========================================================= Thomas W.
