The Registry of Toxic Effects of Chemical Substances (RTECS (trademark)) is a database of toxicological information compiled, maintained, and updated by the National Institute for Occupational Safety and Health. The program is mandated by the Occupational Safety and Health Act of 1970. The original edition, known as the `Toxic Substances List,` was published on June 28, 1971, and included toxicologic data for approximately 5,000 chemicals. Since that time, the list has continuously grown and been updated, and its name changed to the current title, `Registry of Toxic Effects of Chemical Substances.` RTECS (trademark) now contains over 133,000 chemicals as NIOSH strives to fulfill the mandate to list `all known toxic substances...and the concentrations at which...toxicity is known to occur.` This database is now available for searching through the Gov. Research-Center (GRC) service. GRC is a single online web-based search service to well known Government databases. Featuring powerful search and retrieval software, GRC is an important research tool. The GRC web site is at http://grc.ntis.gov.
