Chemical Carcinogenesis Research Information System (CCRIS)
Carcinogenicity and mutagenicity test results for over 8,000 chemicals.
CCRIS (Chemical Carcinogenesis Research Information System) is a factual data bank sponsored by the National Cancer Institute. It contains evaluated data and information, derived from both short and long-term bioassays on over 9,000 chemicals. Studies relate to carcinogens, mutagens, tumor promoters, cocarcinogens, metabolites and inhibitors of carcinogens.
