[Salmonella tester strain TA104 for the detection of mutagenic and carcinogenic chemicals in our environment].
We used the Salmonella mutagenicity test for detecting chemical carcinogens as mutagens in the Salmonella typhimurium tester strain TA104 . The mutagenicity of several compounds was assessed by induction of histidine revertants in the TA104 . In each experiment we routinely included positive mutagenesis controls using three different concentrations of known mutagens. The mutagenic chemicals such as sodium azide, hydrogen peroxide and hydroxylamine were found to be mutagenic to TA104 at very low concentration (10(-4) mg/ml). Their mutagenic activity decreased while their concentrations were increased. The effect of acridine orange, 2, 4, 6-trinitrobenzene sulphonic acid, 2- phenylnaphthalene and 20- methylcholanthrene were also found to be mutagenic to TA104 at the concentration of 10(-2) mg/ml. The mutagenicity of other materials such as hair dyes, meat- broth preparations+ and cigarette smoke condensates were also tested, and all of them were found to be mutagenic to TA104 . The highest mutagenic activities were observed at the concentration of 10 mg/ml for two different hair dyes and of 1 mg/ml for cigarette smoke condensates.
