National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Tier II Mutagenic Screening of 13 NIOSH Priority Compounds. Individual Compound Report, Butylene Oxide.

PB83151704

Publication Date	1981
Personal Author	McGregor, D. B.
Page Count	198
Abstract	The Tier II mutagenic screening of butylene-oxide (109999) (BO) was conducted. The unschedule DNA synthesis (UDS) assay was conducted with human embryonic intestinal cells, rat liver S9, and 11 to 7300 micrograms per milliliter BO. A cytogenetic analysis of rat bone marrow cells was performed after in vivo exposure to 250 or 1000 parts per million (ppm) BO for 7 hours per day for 1 or 5 days. Dominant lethal test in male rats and sperm abnormality tests in male mice were performed after in vivo exposure to 250 or 1000 ppm BO for 7 hours per day for 5 days. The sex linked recessive lethal test was performed using Drosophila-melanogaster after a 7 hour exposure to 1000ppm. BO produced no increases in UDS, sperm abnormality frequency, or sex linked recessive lethal mutation frequency. No effects due to BO exposure were observed in the dominant lethal assay. The author concludes that BO showed no mutagenic activity under these test conditions.
