Technical Basis
A review of available sources identified the following: a Level of Concern and a 1-hr rat LC50. Data sources were selected according to the hierarchy listed in Table 3.1.
Toxicity data were evaluated using factors in Tables 3.2, 3.3, and 3.4. The LC50 was selected as the TEEL-3 basis. The LOC was selected as the TEEL-2. TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC
• TEEL-3 = rat 1-hr LC50 (2541 ppm)
This review generated TEEL values that are consistent with those in Rev. 29A.
