Illness in Gulf War veterans. Causes and consequences

In 1990 and 1991, 697 000 men and women of the US armed forces served in the Persian Gulf. During their service these veterans were exposed to a wide array of known and potential hazards to health. These risk factors included extremes of heat and cold, blowing dust, smoke from oil well fires, petroleum fuels and their combustion products, pyridostigmine bromide (administered as pretreatment for potential poison gas exposure), anthrax and botulinum toxoid vaccines, depleted uranium (used in certain artillery shells), infectious diseases, chemical warfare agents, pesticides, and pervasive psychological and physiological stress.1
