endpoint: gene mutation - Evaluation criteria:
- ASSESSMENT CRITERIA: a reproducible and dose-related increase in the number of revertants over background even if the increase was less than twofold is considered to be a positive result. When the chemical elicited no increase in the number of revertants: non-mutagenic response. When there as an absence of a clear-cut dose-related increase in revertants; when the dose-related increase were not reproducible or when the response was of insufficient magnitude to support a determination of mutagenicity, the response was considered questionable.
- Statistics:
- no statistics reported

negative
This study reported that CdO, dissolved in DMSO is not mutagenic in the used test system (Salmonella typhimurium) with or without metabolic activation. - Executive summary:
Mortelmans et al. (1986) reported that cadmium oxide was negative in Salmonella typhimurium with and without metabolic activation tested from 3.3-3333 μg CdO/plate.
