Registry of Toxic Effects of Chemical Substances (RTECS)

Definition

The Registry of Toxic Effects of Chemical Substances (RTECS) is a toxicology database of over 140,000 chemicals compiled, maintained, and updated by the U.S. National Institute of Occupational Safety and Health (NIOSH). Its goal is to include "all known toxic substances... and the concentrations at which... toxicity is known to occur".

Additional Info

RTECS was mandated by the same act that created the U.S. Occupational Health and Safety Administration (OSHA). It was originally called the Toxic Substances List. RTECS data is obtained from the open scientific literature and maintained by NIOSH.

Unlike many other government databases, RTECS is only available from vendors (if you dislike this, which you should, consult your congressional representatives). NIOSH has additional info and a vendor list if you would like access to the database. The price is roughly $300 U.S. for a one-year CD-ROM subscription and $250 for renewals.
