Technical Basis
A review of available sources identified acute toxicity data (LD50) for several species and routes. Reported GHS health hazard ratings (H315 and H319, Category 2; H335, inhalation Category 3, H302, Category 4) indicate a mid-level health hazard, approximately equivalent to an HHR=2 (TEEL-3 = 790 mg/m3). 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 most preferred species and route toxicity data, a dog oral LD50, was selected as the TEEL-3 basis. The magnitude of the resultant TEEL-3 value is consistent with the GHS health hazard analysis. 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 = Dog oral LD50 (2000 mg/kg)
This review generated PAC values inconsistent with Rev. 29A. The Rev. 29A TEEL-3 basis was a rat oral LD50, while the current TEEL-3 basis is a more preferred species toxicity data, a dog oral LD50 (dog > rat, Section 3.3.2). The Rev. 29A and current TEEL-2 and TEEL-1 use the same methodologies, with differences due to the change in TEEL-3.
