Carcinogenic potency is compared in rodents with acute toxicity for a group of chemicals (155) which were tested independently of and mostly before the NCl/NTP program. For the entire data set and several subsets, we find partially biased statistically significant linear relationships between potency and the inverse of LD50. On average, the chemicals studied outside the NCl/NTP program are more carcinogenic compared to their acute toxicity than the NCl/NTP chemicals. Analysis shows a clear unbiased upper bound for carcinogenic potency. The correlation between potency and acute toxicity is robust with respect to species and route of administration. We find good agreement between oral and inhalation experiments, for toxicities and carcinogenicities.
