Technical Basis
A review of available sources identified a rat oral LD50 that was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, and 3.4. This conservatism is supported by the reported GHS health hazard ratings (H315, Category 2; H335, inhalation Category 3) indicate a mid-level health hazard, approximately equivalent to an HHR=2 (790 mg/m3). 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 = Rat oral LD50 (5000 mg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was a TLV-TWA for particles not otherwise specified (Section 3.5.2), from which the TEEL-2 and TEEL-3 were derived (Table 3.5). The current TEEL-3 basis is a rat oral LD50, from which TEEL-2 and TEEL-1 were derived (Table 3.5).
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat oral LD50 (5000 mg/kg)
