Abstract
p-Aminophenol (PAP; as a component of, e.g., hair dyes, photographic developers, as adsorbent in gas filters, as a metabolite of various fungicides, pesticides and drugs) has been tested for genotoxicity in Drosophila by means of the sex-linked recessive lethal test (SLRLT) and the somatic mutation and recombination test (SMART) of the wing. While the SLRLT was not significant, the SMART clearly indicated that the compound has genotoxic properties in this in vivo test in agreement with a majority of mammalian short-term tests in vitro and in vivo. The reducing agent dithiothreitol enhanced the genotoxic effects of PAP in the SMART; the reasons for this interaction remain to be elucidated.
