Technical Basis
From the limited toxicity data available, a LD50 rat oral dosage is chosen for TEEL-3 development. This selection concurs with the previous revision. 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 = 11,160 mg/kg
The original and new recommendation TEEL-3 values are based on rat oral LD50 data. The updated recommendation used this value to calculate the other TEEL values. In contrast, the Rev. 29 recommendation used rat oral TDLo for TEELs -2 and -1. However, the previously cited rat oral TDLo values were not found.
Both analysts used same method, resulting in the same TEEL values. The review resulted in a recommendation to revise TEEL-1 and TEEL-2 values. TEELs were rounded to two significant figures and converted from referenced units to either ppm or mg/m3, providing both values.
