 Fact Sheet: Mustard Gas Exposure and Long-Term Health Effects   (Site not responding. Last check: 2007-11-06)
In 1991, the Department of Veterans Affairs (VA) relaxed requirements for evaluating mustard gas-related compensation claims because of the confidentiality of some of the World War II testing and a lack of military medical records and followup.
At that time, a review of studies of the effects of mustard gas exposure led VA to publish regulations authorizing service-connection and disability compensation payments to veterans who were exposed to significant levels of mustard gas and who suffer from chronic forms of certain diseases.
Veterans who were exposed to significant amounts of mustard gas and have health problems that may be compensable -- or their survivors -- may contact the nearest VA regional office at 1-800-827-1000 for more information about benefits.
