Genotype Confirmation
The following genotype specifications of the test system were routinously tested every three months:
• histidine deficiency
• ampicilline resistance (pKM 101, for TA97a, TA98, TA100, TA102; control : TA 1535)
• Sensitivity against crystal violet (deep rough, for TA 97a, TA98, TA100, TA102, TA1535)
• UV-sensitivity (uvrB, only TA102 may show growth)
• ampicilline-tetracycline-resistance (pAQ1, TA102) - Evaluation criteria:
- A substance is considered to have mutagenic potential, if a reproducible increase of revertant colonies per plate exceeding an increase factor of 2 in at least one strain can be observed. A concentration-related increase over the range tested is also taken as a sign of mutagenic activity.
- Statistics:
- The mean values and standard deviations of each fourfold determination are calculated as well as the increase factor of revertant induction (revertants divided by spontaneous revertants) of the test item solutions and the positive controls.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
Slag, ferrous metal, blast furnace (air cooled - ABS), granular (8-11 mm) is not mutagenic under the conditions of the test. - Executive summary:
For determination of the mutagenic potential of slags, ferrous metal, blast furnace (air cooled - ABS), granular (8-11 mm) the Bacterial Reverse Mutation Test following OECD 471 and EU B.13/14 was performed. As the slags are inorganic solids, a leachate of the slags was prepared as prescribed by DIN 38414-S4 (100 g/L).
Two experiments were performed:
In the first experiment, 5 concentrations of the leachate (ranging from 10060 to 101 µg/plate, nominal concentration) were used. 5 genetically manipulated strains of Salmonella typhimurium (TA 97a, TA 98, TA 100, TA 102 and TA 1535) were exposed to the slags both in the presence and in the absence of a metabolic activation system (S9) for 48 hours, using the plate incorporation method.
In the second experiment, 5 concentrations of the leachate (ranging from 10160 to 635 µg/plate) were tested using the pre-incubation method.
Both experiments yielded the same results: None of the concentrations caused any significant increase in the number of revertant colonies in the tested bacterial strains. The slags had no mutagenic effect towards Salmonella typhimurium, strainsTA 97a, TA 98, TA 100, TA 102 and TA 1535. The slags exhibited no sign of toxicity towards the bacteria. No inconsistencies were observed in the sterility control and in the determination of the titre. The numbers of spontaneous revertants of the negative controls were in the normal range, and all positive controls showed mutagenic effects with and without metabolic activation.
Slags, ferrous metal, blast furnace (air cooled - ABS), granular (8-11 mm) are not mutagenic under the conditions of the Ames test.
