Additional information

The purpose of this study was to evaluate the mutagenic potential of the test substance by measuring its ability to induce reverse mutations at selected loci of several strains of Salmonella typhimurium and at the tryptophan locus of Escherichia coli strain WP2 uvr A in the presence and absence of Aroclor-induced rat liver S9. All criteria for a valid study were met as described in the protocol. The results of the Bacterial Reverse Mutation Assay indicate that, under the conditions of this study, Precursor PD 206 did not cause a positive mutagenic response with any of the tester strains in either the presence or absence of Aroclor-induced rat liver S9.


Short description of key information:
The results of the Bacterial Reverse Mutation Assay indicate that, under the conditions of this study, Precursor PD 206 did not cause a positive mutagenic response with any of the tester strains in either the presence or absence of Aroclor-induced rat liver S9 according to OECD guideline 471.

Endpoint Conclusion:

Justification for classification or non-classification

Precursor PD 206 was considered to be non-mutagenic under the condition of this test. According to the classification criteria, Precursor PD 206 does not need to be classified for genotoxicity.
