- Details on test system and experimental conditions:
- All compounds were tested on 2 slightly different minimal media: one (in the following named ZLM medium) is a modified minimal medium for E. coli , and the other is the Vogel-Bonner (VB) medium. ZLM medium contained (in g/l): tri-Na- citrate.2H20 (0.82), K2HPO4-3H20 (4.60), KH2PO4 (1.50), (NH4)2SO4 (1.00), MgSO4.7H20 (0.10) and glucose (17.0).
The concentration of citrate was 3.5 times higher in VB medium than in ZLM medium. The concentrations of the other ions are up to 2-fold higher in VB medium. - Statistics:

Applicant's summary and conclusion
- Conclusions:
- Mutagenicity of zinc sulfate was tested with a bacterial reverse mutation test. The outcome of the test was negative, both with and without metabolic activation.
Under the conditions of this test, zinc sulfate was considered to be non-mutagenic. - Executive summary:
Mutagenicity of zinc sulfate was tested with a bacterial reverse mutation test.
Salmonella typhimurium strains TA1535, TA1537, TA98, TA100 and TA1538 strain were treated with the test material in Vogel-Bonner (VB) & ZLM medium (modified minimal medium for E. coli) at minimal five dose levels, up to 3,600 µg/plate, both with and without activation by the S9 liver fraction from Aroclor-pretreated rats.
The positive control chemicals used in the test induced marked increases in the frequency of revertant colonies, both with or without metabolic activation. No significant increases in the frequency of revertant colonies were observed for any of the bacterial strains, with any dose of the test material, either with or without metabolic activation.
The test material was considered to be non-mutagenic under the conditions of this test.
