[DNA damage after treatment in-vivo with several aromatic amines: 2,4-diaminotoluene, 4-aminobenzene (aniline) and paradimethylaminoazobenzene (butter yellow)].

Three aromatic amines, 2,4 diaminotoluene, aminobenzene and paradimethylaminoazobenzene were examined for their capability of damaging rat liver DNA. Compounds were tested by the "in vivo"/DNA alcaline elution assay. 2,4 diaminotoluene was very positive, aminobenzene weakly positive, paradimethylaminoazobenzene probably negative. All the compounds were tested at doses already clearly toxic.
