|July 1, 1979
Summary
Ethylene oxide, a common sterilant, shows mutagenic potential in various tests. However, current evidence is insufficient to classify it as a human mutagen at regulated exposure levels.
Area of Science:
- Toxicology
- Genetics
- Environmental Health
Background:
- Ethylene oxide is a widely-used sterilant with proposed exposure restrictions.
- Evidence suggests ethylene oxide possesses mutagenic properties.
Purpose of the Study:
- To review existing data on ethylene oxide's mutagenicity.
- To evaluate potential human risk based on current mutagen testing guidelines.
Main Methods:
- Review of data from sub-mammalian (bacterial, eukaryotic) and mammalian systems.
- Analysis of point and chromosomal mutations.
- Consideration of current mutagen testing guidelines.
Main Results:
- Substantial evidence indicates ethylene oxide is mutagenic in various test systems.
- Limited studies in mammalian systems were also reviewed.
- Data was contextualized within current mutagen testing guidelines.
Conclusions:
- The available evidence is not sufficient to classify ethylene oxide as a human mutagen at currently acceptable exposure levels.
- Further evaluation may be needed depending on updated risk assessments.
