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 = 500 mg/kg
Aminodiphenyl, p- is also known as 4-biphenylamine (as listed in PubChem). Rat toxicity data (LD50, rat, oral, dosage=500 mg/kg) was selected over data that used dog toxicity. Although dogs are the preferred species, LD50 is preferred over LDLo. Therefore, the rat LD50 value was used.
Both analysts converged 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.
