Both the mutagenic and cytotoxic effects of the test material on these strains were analysed. As only slight cytotoxicity was observed at the highest concentration, subsequent mutagenicity testing on the four bacterial strains also used 5000 µg/plate as the top concentration; other concentrations used were 50, 150, 500 and 1500 µg/plate (with and without metabolic activation). - Vehicle / solvent:

METHODS OF SLIDE PREPARATION AND STAINING TECHNIQUE USED: not applicable
NUMBER OF CELLS EVALUATED: not applicable
DETERMINATION OF CYTOTOXICITY
- Method: measured by the presence of an incomplete background lawn. - Evaluation criteria:
- A test substance is considered positive (mutagenic) in the test if it induced at least a 2-fold increase (with some evidence of a positive dose-response) in the number of revertants with respect to the number induced by the solvent control in two separate experiments, with any of the tester strains, either with or without metabolic activation.
A test substance is considered to be negative (not mutagenic) if the total number of revertants in any tested strain at any concentration is not greater than 1.5 times the solvent control value, with or without metabolic activation. - Statistics:
- No statistical evaluation was performed.

Applicant's summary and conclusion
- Conclusions:
- In an OECD Test Guideline 471 study, to GLP, calcium nitrite (hydrate) showed evidence of mutagenic activity in Salmonella typhimurium strains TA100 and TA1535 (but not in TA98 or TA1537) in the presence and absence of mammalian metabolic activation.
- Executive summary:
The genotoxic potential of calcium nitrite (hydrate) was assessed in an in vitro bacterial reverse mutation (Ames) assay, conducted according to OECD Test Guideline 471 and to GLP.
In a preliminary toxicity test, Salmonella typhimurium strains TA98, TA100, TA1535 and TA1537 were exposed to test material concentrations of 0, 5, 50, 500 or 5000 µg/plate (equivalent to up to 1700 µg calcium nitrite/plate), both in the presence and absence of metabolic activation by rat liver fraction S9 (alongside appropriate vehicle controls). Only slight cytotoxicity was observed at the highest concentration only, therefore this was used as the highest test concentration in the mutagenicity assay.
Triplicate cultures of the four bacterial strains were exposed to the test material at concentrations of 50, 150, 500, 1500 or 5000 µg/plate, both with and without S9 (alongside appropriate vehicle and positive controls). These cultures were incubated for 72 hours at 37°C before being inspected for signs of cytotoxicity and for the incidence of revertant colonies. The main mutagenicity experiment was repeated using the same test material concentrations and following an identical procedure.
No signs of cytotoxicity were observed for any of the tested strains, at any of the tested concentrations, in either of the mutagenicity experiments. Large, dose-related increases in the number of revertant colonies were seen for S. typhimurium strains TA100 and TA1535 (with and without S9) in both mutagenicity experiments. No significant, dose-related increase was seen in S. typhimurium strains TA98 or TA1537 (both in the absence and presence of S9). The concurrent positive control substances demonstrated the sensitivity of the assay and the metabolising activity of the liver preparations.
Under the conditions of this assay, calcium nitrite (hydrate) showed evidence of mutagenic activity in bacteria.
