| System | RfC (mg/m3) | Basis | PoD | UF | Confidence |
|---|---|---|---|---|---|
| Hepatic | 1 x 10-1 | Increased relative liver weight. | LOAEL : 395 mg/m3 | 3000 | Low |
Species Studied: Rat
Duration: 7 hr/d, 5 d/wk, for 195 days (135 exposures)
Principal Study: Torkelson et al. 1960
Note: The LOAEL of 1958 mg/m3 was converted to a LOAEL-HEC of 395 mg/m3.
