Cis-1,2-dichloroethylene was administered daily by corn oil gavage to male and female Sprague-Dawley rats at the following dose levels: 1.0, 3.0, 10.0 and 22.0 mmol/kg/day for 14 days. Doses gavaged during the 90-day subchronic study were 0.33, 1.00, 3.00 and 9.00 mmol/kg/day. There were no compound-related deaths or histopathological changes demonstrated. Significant increases in relative liver weights were seen after 14- and 90-days of treatment in both sexes. This study demonstrates some indication of toxicity at subacute and subchronic exposure levels as low as 0.33 mmol/kg/day. Implications of liver abnormalities were demonstrated at an exposure level of 1 mmol/kg/day while kidney abnormalities (relative weights) were demonstrated at an exposure level of 0.33 mmol/kg/day.
