| Hazard Information | Back Directory | [Uses]
Dibenzo[a,i]pyrene is a polycyclic aromatic hydrocarbon (PAH) with potent carcinogenic activity. Dibenzo[a,i]pyrene was shown to induce DNA adduction, tumorigenicity as well as Ki-ras oncogene mutations in strain A/J mouse lung. Dibenzo[a,i]pyrene has been shown to be present in cigarette smoke condensate and in automobile exhaust gas in small quantities. | [Definition]
ChEBI: Dibenzo[a,i]pyrene is an ortho- and peri-fused polycyclic arene. | [General Description]
Colorless solid. Water insoluble. | [Air & Water Reactions]
Insoluble in water. | [Reactivity Profile]
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIBENZO(A,I)PYRENE(189-55-9), and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. | [Health Hazard]
Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution. | [Fire Hazard]
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. | [Safety Profile]
Confirmed carcinogen withexperimental neoplastigenic and tumorigenic data.Mutation data reported. When heated to decomposition itemits acrid smoke and irritating fumes. | [Toxics Screening Level]
The IRSL and SRSL were derived from the inhalation unit risk (IUR) factor for B(a)P of 1.76E-3 per μg/m3. |
