The BCERF program on the Cancer Risks of Environmental Chemicals in the Home and Workplace closed on March 31, 2010. No further updates will be made to this web site. Please go Cornell University’s eCommons web site to access BCERF’s archived research and educational materials (

EnviroChem and Cancer Database (ECCD)

The National Toxicology Program has identified 42 chemicals that cause mammary tumors (breast tumors) in laboratory mice. The EnviroChem and Cancer database provides a snapshot of important information about each of those chemicals in the following categories:

The complete database is available as a six-page document. See our Print page to get the file.

BCERF will add information to the database as it becomes available. Every effort has been made to provide up-to-date information, but in certain cases data was not available for all categories. Because the EnviroChem and Cancer database provides abbreviated information, it should be considered to be starting point for those seeking information on these chemicals. The user should refer to the Material Safety Data Sheets for information on the toxicology and precautions to be used when handling these chemicals or products that contain these chemicals.

You can search the EnviroChem and Cancer Database or print an information sheet containing complete data about all of the chemicals.
