- - Principle of test:
The aim of this Study was to perform an initial screening for genotoxic activity and, in particular, for point mutation-inducing activity. The mutagenic potential of the test item is assessed in the Ames strains of Sa/mone/la typhimurium and Escherichia coli, in the presence and absence of a metabolic activation system.
- Exprerimental procedure:
Several days before the beginning of the Study, the bacterial strains contained in vials were defrosted and grown on master plates in order to obtain pure cultures. These plates were stored between 2 and 8 °C until required for the test.
The histidine and tryptophan requirements, the absence or presence of the pKM 101 plasmid, the rfa factor (sensitivity to crystal violet in Salmone/la) and the uvrβ factor in Salmonel/a (sensitivity to ultraviolet rays) were checked in the strains used to prepare the inoculum.
Approximately sixteen hours before each test, an inoculum was prepared for each of the five bacterial strains in 20 mL of nutrient broth and was incubated in a bath at 37 ± 1 °C with agitation.
An study plan was performed. See the information of the preliminar study on appendix II (from page 33 to 43) of the study report.
Also an study plan amendment was permormed. See the information of the preliminar study on appendix III (from page 44 to 48) of the study report. - GLP compliance:

- Details on test system and experimental conditions:
- EXPERIMENTAL PROCEDURE
Preincubation: 0.1 ml of the bacterial culture and 0.1 ml of the dilution of the test item, or 0.1ml of the positive control or 0.1 ml of the solvent, were added to 0.5 ml of S-9 mix with cofactors (or 0.5 ml of phosphate buffer).
This was incubated for 20 minutes at 37 ± 1 °C under agitation. lt was then added to 2 mL of top agar melted at 45 ± 1 °C which contained a sterile solution of 0.5 mM of L-Histidine/0.5 mM Biotin in the proportion of 1/1 O for the Sa/mone//a typhimurium strains.
For the Escherichia coli, 0.25 ml of a sterile solution of tryptophan and 5 ml of nutrient broth were added for every 1 00 ml of agar.
As the metabolizing enzymes of S-9 were not stable at 45 °C, the contents of the test tubes were mixed immediately in a rotamixer, poured over the agar plates which were rotated to spread the layer, and then left to solidify.
Once the agar had solidified, the plates were inverted and incubated at 37 ± 1 °C for 48-72 hours.
After this incubation period, the number of revertant colonies that had grown on each plate was counted.
- OTHER:
POSITIVE CONTROLS
In parallel to the Study of the test item, Batch 7108023, known mutagenic
products were tested in order to check the sensitivity to mutagenic agents of the strains used. See in the section 5.8 "positive controls" (page 13) of the study report the results of the positive controls.
The solvents used were sterile distilled water for AZ and DMSO for 9Ac, 2NF, 4NQO and 2AA.
NEGATIVE CONTROLS
The solvent used to dilute the test ítem was distilled water and it was tested as the negative control.
NONTREATED CONTROLS
0.1 mL of the suspension of each bacteria! strain was added to 0.5 mL of phosphate buffer or S-9. - Rationale for test conditions:
- Not specified
- Evaluation criteria:
- There are several criteria for determining a positive result, such as a concentration-related increase over the range tested and/or a reproducible increase at one or more concentrations in the number of revertant colonies per plate in at least one strain with or without metabolic activation system. Biological relevance of the results should be considerad first. Statistical methods may be used as an aid in evatuating the results; However, statistical significance should not be the only determining factor for a positive response.
A test item for which the results do not meet the above criteria is considerad nonmutagenic in this test.
Although most experiments will give clearly positive or negative results, in rare cases the data set will preclude making a definite judgement about the activity of the test item. Results may remain equivocal or questionable regardless of the number of times the experiment is repeated.
Positive results from the bacterial reverse mutation test indicate that a substance induces point mutations by base substitutions or frameshifts in the genome of either Salmonella typhimurium and/or Escherichia coli. Negative results indicate that under the test conditions, the test item is not mutagenic in the tested species. - Statistics:
- STATISTICAL ANALYSIS
The results, together with the means and standard deviations for each group, are presented in separate tables for each test, bacterial strain and S-9 concentration.
The comparisons between the results for the standard products and the Control were made using Student's t test, with a level of significance of p < 0.01 and p < 0.05 [4].
The statistical comparison of the different test-item concentrations and the Control was carried out, for all the bacterial strains, both with and without metabolic activation, using a one-way analysis of variance with a level of significance of p < 0.05 [Steel RGD, Torrie JH, Dickey DA.

Additional information
Although the physical state described on section 1.2 (composition) and 1.4 (Appearance/ physical state/ colour) for the substance Reaction mass of copper digluconate, sodium sulphate and copper sulphate is solid, the manufacturing method (described in section 3.5.1.) only allows substance synthetisation as a dissolution, containing at most a 50% of Reaction mass of copper digluconate, sodium sulphate and copper sulphate.
Therefore, studies for physical hazards determination, were developed using solid substance form, whereas for toxicology and ecotoxicology hazards, the dissolution (≤ 50% Reaction mass of copper digluconate, sodium sulphate and copper sulphate) form was used as stated on guidelines.
In consequence, the substance has been classified taking into account that it always will be in a dissolution in a maximum of 50% of concentration.
Justification for classification or non-classification
The three test performed were negative for this endpoint.
