Estimate of Subchronic Reference Dose for Oral Exposure (RfD)Last Updated: 09/03/2009
| System | RfD (mg/kg-day) | Basis | PoD | UF | Confidence |
|---|---|---|---|---|---|
| Urinary | 9 x 10-2 | Increased serum creatinine | BMDL : 92 mg/kg-day | 1000 | Low |
Species Studied: Rat
Duration: 14 days prior to mating through day 3 of lactation
Principal Study: Tanaka et al. 1999
Note: Benmark dose modeling was used to calculate a BMDL(1SD). The LOAEL is 300 mg/kg-day.
