Technical Basis
A review of limited sources identified the following: rat LC50 and oral LD50 toxicity data. These sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were evaluated using the type of exposure, species, and route preferability stated in Sections 3.3.1, and 3.3.2. The concentration was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4).
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = rat inhalation LC50 (650 mg/m3/4H)
This review generated TEEL values that are consistent with those in Rev.29A.
