Technical Basis
No exposure limits were found for this chemical. 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, Dog, Oral, Dose = 500 mg/kg
Analyst’s 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. Comparing the preferability of the available toxicity data, dog oral data was chosen for TEEL development. The results are comparable to Rev29A; the TEEL-3 difference is attributed to rounding.
