Hi Nick & All,
With respect to Atrazine, and pesticides in general, I would guess =
that roughly 95% of the research effort has been directed to =
environmental protection. Have a look at Pesticides in the Soil =
Environment: Processes, Impacts, and Modeling, Soil Sci. Soc Amer. Book =
Series No. 2., ed. H.H.Cheng, 530 pp.,1990.
Spray and weigh trials are fairly straightforward but making sure =
that materials and their degredation products do not lead directly to =
environmental harm is a huge undertaking.

David,
no confusion here. Listserve focus is on nature not human safety. =

If we want to take a stand on pesticides it would be for their =

pollinators.
