APPENDIX D (continued) CALCULATION EQUATIONS 3. Margin of Safety: Margin of Safety NOEL exposure level 4. Human equivalency in potency from animal data to human: The equivalency in potency from animal to human is calculated based on the body weight to the 3/4 power (Davidson et al., 1986; Travis and White, 1988). Dose A Dose H × BW H BW 3 / 4 A BW A BW 3 / 4 H Dose H Dose A x ( BW A BW H ) 1 / 4 Therefore, q 1 H q 1 A ×(BW H BW A ) 1 / 4 BW=body weight, A=animal, and H=human. Body weights used were: 70 kg for human, 0.50 kg for rat, and 0.037 kg for mouse.
