Abstract
The induction of squamous cell carcinomas and papillomas in a total of 1,950 mice in a lifelong skin-dropping experiment with different doses of automobile exhaust condensate and its fractions is described. The dose-response studies indicate that local oncogenic activity of automobile condensate is contained primarily in its polycyclic aromatic hydrocarbon-fractions. Findings in lung tumor incidences are given. Results of the sebaceous gland suppression screening test were comparable to findings of the skin-dropping experiments.
