DEVELOPMENT OF HEPATOMAS IN MICE TREATED WITH BENZENE HEXACHLORIDE

Abstract

The chronic toxicity of benzene hexachloride in male dd mice was examined. Seventy-four mice were divided into 4 groups of Group 1 660.0ppm, Group 2 66.0ppm, Group 3 6.6ppm, Group 4 control. The tumors developed in the liver of all 20 rats in Group 1. No remarkable changes were seen in the livers of mice in Groups 2, 3, and 4.
