Dominant lethal effects of n-butyl glycidyl ether in mice.

Using the dominant lethal assay, the ability of n-butyl glycidyl ether to induce mutations in male mice was investigated. No significant dose-related changes either in pregnancy rates or in average number of implants per pregnant female were found. However, while the results were not altogether conclusive, there was evidence of a significant increase in fetal death rates by the end of the first week after the highest dosage was administered.
