Abstract
In order to reinvestigate the minimal dietary levels of certain chlorinated hydrocarbon insecticides required to produce pathologic change, materials were fed to rats at the following concentrations: Chlordane, 2.5 and 25 ppm; Dieldrin, 2.5 and 25 ppm; lindane, 50 and 100 ppm; and Toxaphene, 50 and 200 ppm. The control diet contained less than 0.6 ppm of D.D.T. as the only known contaminating insecticide. The experimental animals were observed clinically and then serially killed after from two to nine months' exposure to the poison. Tissues from liver, kidney, and spleen were examined histologically.
