Results and discussion
Test results
- Species / strain:
- Chinese hamster lung fibroblasts (V79)
- Metabolic activation:
- with and without
- Genotoxicity:
- negative
- Cytotoxicity / choice of top concentrations:
- no cytotoxicity
- Additional information on results:
- See attached OECD Toolbox study
In the first test set with no info on metabolic activation PDPI scored -0.6, ie negative for genotoxicity and cytotoxicity
In the second test set with metabolic activation PDPI scored +0.2, ie ambiguous
In the third test set without metabolic activation PDPI scored -1, ie negative for genotoxicity and cytotoxicity
