CAS Number:  189-55-9

Chemical Name:  Dibenzo[a,i]pyrene

Type of Toxicity:  cancer

Listing Mechanism:  State's Qualified Experts (SQE)

Date Listed:  1-Jan-88

NSRL (No Significant Risk Level) or MADL (Maximum Allowable Dose Level):  0.0050 (oral) µg/day

Where a source or product results in exposures by multiple routes, the total exposure must be considered. For example, the MADL for benzene is exceeded when the absorbed dose exceeds 24 µg/day. If only inhalation and oral exposure occurs, the benzene MADL is exceeded when: (oral dose ÷ 24 µg/day) + (inhalation dose ÷ 49 µg/day) > 1.0.
