Technical Basis
A review of available sources was able to identify exposure limit and toxicity data for this chemical. The rat oral LD50 toxicity was selected as the TEEL-3 basis. A TEEL-2 was calculated from this TEEL-3, in accordance with guidelines in the handbook (see Table 3.5.) The TLV-STEL exposure limit was selected as the TEEL-1 as the most preferred data source (Table 3.1.)
TEEL-1 = TLV-STEL (20 mg/m3)
TEEL-2 = TEEL-3/6
TEEL-3 = Rat oral LD50 (1650 mg/kg)
This review generated values that are consistent with Rev. 29A.
