Book excerpt: Excerpt from Gypsy Moth Management in the United States, Vol. 3 of 4: A Cooperative Approach; Final Supplemental Environmental Impact Statement; Appendixes F-I, Risk Assessments Sensitive terrestrial insects are the only organisms likely to be seriously affected by exposure to B. Tk. Or its formulations. All sensitive terrestrial insects are lepidoptera and include some species of butterfly, like the endangered Kamer blue and some swallowtail butterflies and promethea moths. At the application rates used to control gypsy moth populations, mortality rates among sensitive terrestrial insects are likely to range from approximately 80% to 94% or more. The risk characterization for other wildlife species is unambiguous: under foreseeable conditions of exposure, adverse effects are unlikely to be observed. In terms of potential human health effects, formulations of B. T. K. Are likely to cause irritation to the skin, eyes, and respiratory tract; however, serious adverse health effects are implausible. For members of the general public, exposure levels are estimated to be below the functional human noael for serious adverse effects by factors of about to [4 million]. At the extreme upper range of exposure in ground workers, exposure levels are estimated to be below the functional human noael for serious effects by a factor of 25. This assessment is based on reasonably good monitoring data, conservative exposure assumptions, and an aggressive and protective use of the available toxicity data.
