Tier II Mutagenic Screening of 13 NIOSH Priority Compounds, Individual Compound Report, BIS(2-Methoxyethyl) Ether.
NIOSH 1981 Jul:185 pages
Bis(2-methoxyethyl)-ether (111966) (BME) was subjected to a tier II mutagenic screening program. Screening assays included unscheduled DNA synthesis (UDS) assay in human diploid fibroblasts with exposures of 3 hours duration and concentrations up to 19,000 micrograms per milliliter of culture medium; dominant lethal test in male rats with exposures to atmospheres containing 250 parts per million (ppm) or 1000ppm BME for 7 hours per day for 5 days; sperm abnormality test in male mice using the same exposures conditions; cytogenetic test in male and female rat bone marrow cells using the same exposure conditions or a single exposure of 7 hours duration; sex-linked recessive lethal test in Drosophila-melanogaster with exposure to atmospheres of 250ppm for 2.75 hours. There was no increase in UDS in cells treated with BME; clinical signs of toxicity occurred in animals exposed to 1000ppm BME atmospheres; male rat fertility was drastically reduced following exposure to 1000ppm BME in the dominant lethal test; a significant reduction in total aberrant cell frequency occurred; and abnormal sperm frequency was increased. The author concludes that BME may be a weak mutagen, but the adverse effect upon reproductive capacity is probably the more important aspect of its toxicology.
