Technical Basis
A review of available sources identified exposure limits (ERPGs) and acute toxicity data (LD50) for several species and 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 ERPGs were selected as TEELs, due to their use priorities (Section 1).
• TEEL-1 = ERPG-1 (0.2 ppm)
• TEEL-2 = ERPG-2 (2 ppm)
• TEEL-3 = ERPG-3 (20 ppm)
This review generated TEEL values that are consistent with Rev. 29A*.
