Technical Basis
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 = 6500 mg/kg
Analysts’ methods align with the values presented in Rev 29A and did not result in a change.
TEELs were rounded to two significant figures and converted from referenced units to either ppm or mg/m3, providing both values.
