Technical Basis
A review of limited sources identified the following: rat LC50 toxicity data. This was selected as the TEEL-3 basis and scaled to 60-minute equivalent exposure using the ten Berge equation (Section 3.3.4). The TEEL-1 and TEEL-2 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat LC50 (>1820 mg/m3/4H)
This review generated TEEL values that are more conservative and therefore inconsistent with Rev. 29A. In Rev. 29A the TEEL-3 was based on rabbit dermal LDLO data, however the current recommendations are based on data of a more preferred species and route (rat, inhalation).
