Technical Basis
A review of available sources identified acute toxicity data (LD50) for several species and routes. In addition, analysts evaluated toxicity data (LD50) for C14-C20 aliphatic (≤ 2% aromatic) Hydrocarbon Solvents Category. 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 rat LD50 for the hydrocarbon solvents category was a large range (5.0 to 36.0 g/kg); considering this, analysts instead selected the mouse intravenous LD50 as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Mouse intravenous LD50 (3494 mg/kg)
This review generated PAC values consistent with Rev. 29A*.
