DURATION

SELECTION AGENT (mutation assays): Histidin requirement
NUMBER OF REPLICATIONS: 3 plates per strain/dose with and without S9 mix; 2 independent experiments
DETERMINATION OF CYTOTOXICITY
- Method: back ground lawn - Evaluation criteria:
- The increase factor f(I) of revertant induction (mean revertants divided by mean spontane-ous revertants) and the absolute number of revertants, mean revertants less mean spontaneous revertants) were also calculated.
A test item is considered to have mutagenic potential, if a significant, reproducible increase of revertant colonies per plate (increase factor >/= 2) in at least one strain can be observed. A concentration-related increase over the range tested can also be taken as a sign of mutagenic activity.

Under the test conditions, the test item is not mutagenic in the Bacterial Reverse Mutation Test using Salmonella typhimurium, strains TA97a, TA98, TA100, TA102 and TA1535. - Executive summary:
In a reverse gene mutation assay in bacteria according to OECD Guideline 471, the strains TA 1535, TA 97a, TA 98, TA 100 and TA 102 of S. typhimurium were exposed to Reaction mass of 1,3-benzene disulfonic acid and sulfuric acid in the presence and absence of mammalian metabolic activation (rat liver S9-mix induced by Aroclor 1254).
Strains were exposed to the test item, diluted in water, at concentrations of 50, 150, 500, 1500 and 5000 µg / plate in the first experiments (1a and 1b) and to 313, 625, 1250, 2500 and 5000 µg/plate in the second experiments (2a and 2b). The first experiments were conducted using the plate incorporation method; in the second experiments the pre-incubation method was used.
In neither of the tests precipitation or signs of toxicity towards the bacteria were observed at any concentration.
There was no evidence of induced mutant colonies over background up to the limit concentration of 5000 µg/plate.
The positive controls induced the appropriate responses in the corresponding strains and activity of metabolic system was confirmed. Values for the spontaneous revertants of the negative controls were in the normal range.
This study satisfies the requirement for Test OECD 471 for in vitro mutagenicity (bacterial reverse gene mutation) data.
The test item is considered as not mutagenic under the conditions of the test.
