- with and without
- Metabolic activation system:
- S9 fraction from liver of rats treated with Arochlor 1254
- Test concentrations with justification for top dose:
- 5000 μg/plate, 1500 μg/plate, 500 μg/plate, 150 μg/plate and 50 μg/plate
Controls
- Untreated negative controls:
- no
- Negative solvent / vehicle controls:
- yes
- True negative controls:
- not specified
- Positive controls:
- yes
- Positive control substance:
- sodium azide
- benzo(a)pyrene
- other: 4-Nitro-1,2-phenylene Diamine 2-Amino-Anthracene, 2-Aminoanthracene
- Details on test system and experimental conditions:
- Two valid experiments were undertaken, first using the plate incorporation method and then using the preincubation method, according to guideline procedures.
- Evaluation criteria:
- The substance was considered to have mutagenic potential if a reproducible increase in the number of revertant colonies on the place exceeded an increase factor of 2 in at least one strain. A concentration-related increase over the range tested is also taken as sign of mutagenic activity.

Any other information on results incl. tables
ZEF 6099/100 showed no precipitates on the plates at any of the concentrations in either assay. The bacterial background lawn was not reduced at any of the concentrations and no relevant decrease in the number of revertants was observed in all bacteria strains. The test item ZEF 6099/100 showed no signs of toxicity towards the bacteria strains in both the absence and presence of metabolic activation.
