To convert animal dose to human dose, the following formula may be applied: Human dose (m) = Animal dose mg (human weight\ animal weight) 2/3 d The following formula should be used to calculate the incremental risk (Pexcess) at a given dose: Pdose - Pcontrol Pexcess 1 - Pcontrol where Pcontrol is the risk at zero dose of the chemical.
