Technical Basis
A review of available sources identified the following: LOC, and rat acute toxicity data (LD50) for oral and dermal routes. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The lowest dose for the most preferred, a rat oral LD50 of 19 mg/kg, was selected as the TEEL-3 basis. Although the LOC (0.019 g/m3) was considered as a TEEL-2, it was not selected because 1) there is no clear documentation on its derivation (LOCs are typically based on IDLH values, none of which could be verified), and 2) it resulted in a TEEL-2 greater than the TEEL-3. Instead, the TEEL-2 and TEEL-1 were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (19 mg/kg)
This review generated TEEL values consistent with those in Rev. 29A
