Abstract
Ethylene dibromide (EDB) was administered at 20, 38, and 80 ppm by inhalation to pregnant Charles River CD rats and CD-1 mice for 23 hr/day. The exposures started on day 6 of gestation and lasted for a total of 10 days. Observations were made on maternal welfare and fetal development. The results of this study indicate that (1) EDB is more toxic in adult mice than adult rats, (2) adverse effects on maternal welfare, as measured by weight gain, feed consumption, and survival were observed in both mice and rats, (3) although morphological changes were observed in fetuses from dams exposed to EDB, these effects were observed at concentrations that also affected maternal welfare, and (4) EDB was judged to be only a weak teratogen with little primary effect on development.
