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.
