What does RTECS stand for?

The correct full form of RTECS is "Registry of Toxic Effects of Chemical Substances." This comprehensive database is managed by the National Institute for Occupational Safety and Health (NIOSH) and contains toxicological data on various chemical substances. It is a vital resource for health professionals, toxicologists, and industrial hygiene professionals who need to understand the potential health effects of chemical exposure. The purpose of RTECS is to provide critical information concerning the toxic effects of chemicals encountered in the workplace and beyond, aiding in safety measures and regulatory compliance.

The other options do not accurately reflect the established terminology or purpose associated with RTECS, thus reinforcing that "Registry of Toxic Effects of Chemical Substances" is the correct interpretation of the acronym.
