International Agency for Research on Cancer (IARC) - Summaries & Evaluations

5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

Because of an error in identification, early experiments supposedly made with dibenzo(a,l)pyrene did not in fact deal with this compound. In the only study actually carried out with dibenzo(a,l)pyrene, sarcomas were induced in all animals following subcutaneous administration to mice. It has not been tested by other routes in mice or in other species.

5.2 Human carcinogenicity data

No case reports or epidemiological studies on the significance of dibenzo(a,l)pyrene exposure to man are available. It is likely that it occurs in the environment, but the data available cannot be interpreted because of the identification problem mentioned above.

Subsequent evaluations: Vol. 32 (1983); Suppl. 7 (1987) (p. 62: Group 2B)

For definition of Groups, see Preamble Evaluation.
