The risk of adverse effects to monarchs from Bt corn pollen was assessed in a screening level approach using exposure estimates, host-range information, and probabilistic toxicity to sensitive species (from many published reports). Demonstrated a likelihood of low risk to monarchs from Bt corn pollen. Used a conservative assessment to identify concerns and uncertainties.
Would help the method to have data for toxicity to non-target species, as most of the toxicity database is on target species. Demonstrated the use of conservative risk screening to help focus further research.
