Blinded Gas Victims
Evidence indicates a causal relation between sulfur mustard exposure and the occurrence of excess respiratory and skin cancer, and possibly leukemia. This conclusion is based upon estimates of exposure to sulfur mustard during [World War II] chamber tests, which may have approximated the battlefield exposure of surviving World War I (WWI) soldiers and WWII production workers in Japan and Great Britain. Inadequate exposure information, however, limits precise estimation of the cancer excesses that may be expected.
