Where units are not shown, concentrations are in micrograms per milliliter and time is in hours. Values in parentheses were determined from independent uptake data [2], or were chosen arbitrarily because they do not significantly affect the fit [3].

*

B represents the plateau value of survival (fraction of controls) in the high-concentration limit, and therefore cannot be less than 0. This constraint was included in the optimization process.
