[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.

Gas-liquid chromatographic determination of tertiary-butylhydroquinone (TBHQ) in dried fish, frozen shrimp, vegetable oils, butter, and margarine.

Tertiary-butylhydroquinone (TBHQ) is extracted from foods with ethyl acetate, the solvent is evaporated, the residue is dissolved in n-hexane-ethyl acetate (99 + 1), and the TBHQ is selectively transferred into an aqueous layer (2% sodium chloride) as a separation from food interferences. Finally, TBHQ is reextracted with n-hexane-ethyl acetate (1 + 1), concentrated, and determined by flame ionization gas-liquid chrmoatography. Dried fish, frozen shrimp, vegetable oils, and edible fats were analyzed by the method. More than 85% was recovered when the samples were fortified with 100 ppm TBHQ. Detection limit was 1.0 ppm TBHQ.
