Between 1950 and 1975, about 6,720 service members took part in experiments involving exposures to 254 different chemicals. These experiments were conducted at US Army Laboratories at Edgewood Arsenal, MD. These experiments were conducted primarily to learn how various agents would affect humans. These experiments tested protective clothing and evaluated the impact of chemical warfare agents on military personnel. The VA’s Office of Public Health provides more details on these tests.

There are no tests today that can confirm exposure to agents that occurred decades in the past. However a good history and physical examination can provide valuable information and help determine a Veteran's risk of developing health problems related to the exposure.

Long-term psychological effects are possible from the trauma associated with being a human test subject. If you are concerned about possible effects from exposure during these experiments, please contact your health care provider who can assist you in determining possible exposures and health effects.
