title: Carcinomas of the liver in Osborne-Mendel rats ingesting DDT.
abstract: Osborne-Mendel male and female rats ingested 200, 400, 600, or 800 ppm DDT composed of 81.8% p,p isomer and 18.2% o,p isomer for periods up to 2 years. Male and female rats developed highly significant incidences of hepatocellular carcinomas. The carcinomas varied from well-differentiated to undifferentiated. There was a highly significant increase in carcinomas of the ovary in treated female rats. Lymphosarcomas were also increased in DDT-treated male rats.
