Intraspecies: 10, because perchloryl fluoride is systemically absorbed and the possible increased sensitivity of some humans, especially infants, for developing methemoglobinemia.
Modifying factor: Not applied
Animal-to-human dosimetric adjustment: Not applicable
Time scaling: Extrapolation to different exposure durations was performed using the equation Cn × t = k (ten Berge et al. 1986), where n = 3 for extrapolation to durations of 30-min, 1 h, and 4 h, and n = 1 for extrapolation to 8 h. The 30-min value was adopted as the 10-min value because extrapolating from 4 h to 10 min is not recommended (NRC 2001).
Data adequacy: Adequate
