Chemical Weapons Gateway

Welcome to the Chemical Warfare Agents Gateway Page.

From this page you can access information about chemical agent properties and uses, and defenses against them, and some background on general concepts of chemical warfare.

Recent Additions:

If you accessed or downloaded information from the pages for specific nerve agents (GA, GB, GF, VR, and VX) between December 23, 2004 and January 11, 2005, we strongly urge you to confirm the information with other sources before acting on it. These pages and their backups were selectively corrupted on the night of December 23-24. The pages have been recreated. However, information that was presented on the pages during the period given above may be incorrect or misleading.
