A correction was made to Table 6 (Candidate PODs for Derivation of the Chronic
RfD for PFPrA). The BMDL for increased relative liver weight in adult male rats
was corrected to 6.3 mg/kg-d. The corresponding PODhed was changed to 1.6
mg/kg-d.
18-19
Call-outs to the PODhed were changed to 1.6 mg/kg-d.
19
A correction was made to the calculation of the Chronic RfD to use the PODhed of
1.6 mg/kg-day, resulting in a Chronic RfD of 0.0005 or 5 x 10"4 mg/kg-day.
21
A correction was made to Table 9 [Summary of the Noncancer Reference Values
for PFPrA (CASRN 422-64-0)]. The Reference Value and PODhed were corrected to
0.0005 mg/kg-d and 1.6 mg/kg-d, respectively.
