Dibenzo[a,c]anthracene is a polycyclic aromatic hydrocarbon which are known carcinogens and environmental pollutants.
ChEBI: Dibenz[a,c]anthracene is a carbopolycyclic compound.
Questionable carcinogen withexperimental tumorigenic data. Human mutation datareported. When heated to decomposition it emits acridsmoke and irritating fumes.
Dibenz[a,c]anthracene was
administered dermally to mice, either per se or as part of
initiation–promotion protocols. The working group concluded
that there was limited evidence for animal carcinogenicity.
In later studies on an initiation–promotion study on
mouse skin, low initiating doses gave negative results
when administered subcutaneously to mice, and tumor incidence
was not significantly increased over that observed in
controls when the compound was administered intraperitoneally
to newborn mice.
