Technical Basis
Based on species and route, LC50 rat inhalation data is the most preferable toxicity starting point. However, more credible, and repeatable source information is found for a LD50 rat oral dosage, which was selected for TEEL-3 development. Analysts used toxicity data, applying Table 3.4 and Table 3.5:
TEEL-1 = TEEL-2/11
TEEL-2 = TEEL-3/6
TEEL-3: LD50, Rat, Oral, Dose = 242 mg/kg
The results from both starting points (LC50 inh; LD50 oral) were comparable (7 mg/m3 difference for TEEL-3) while on par with estimates using a Health Hazard Rating (HHR) of 3. These results are more conservative than the values listed in Rev29A, resulting in a recommended change to the TEEL values. TEELs were rounded to two significant figures and converted from referenced units to either ppm or mg/m3, providing both values.
