I am a licensed pesticide applicator, requiring mandatory upgrading seminars for five-year renewals. I use bismuth and TM for waterfowl, know lead is bad stuff for any purpose, doubt it has effect on upland in the wide-open spaces around here; public lands and plantations perhaps another story. I'm suspicious of studies that say an effect is the cause of one thing; it rarely happens in anything. For all the science in the world, we never get the final answer in a biological system. So I'm me on the side of Stan and Geo.
