Technical Basis
A review of available sources identified the following: OEL-STEL (Sweden, Germany), LD50 (guinea pig, mouse, rat) for dermal and oral routes. 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 most preferred species and route, a rat oral LD50, was selected as the TEEL-3 basis. A TEEL-2 was calculated according to Table 3.5. The Swedish OEL-STEL (15-minute, inhalable fraction) was selected as the TEEL-1.
• TEEL-1 = OEL-STEL (Sweden, 5 mg/m3)
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (2330 mg/kg)
This review generated TEEL-3 and TEEL-2 values that are consistent with those in Rev. 29A. The TEEL-1 Rev. 29A basis, a United Kingdom Occupational Exposure Limit (UK OEL,) was a TWA limit. This review found a STEL, which is preferable.
