Personally I can think of no way that depleted uranium exposures of Canadian, British, American, or French personnel in either the Balkan or the Gulf War could have given rise to the adverse health effects that are claimed by the Gulf War veterans. Personally, if I were doing it, I would look at it given that the level of worry amongst veterans varies according to nation, and I believe that the French army has fewer concerns about Gulf War syndrome. It might be best to go back and look at some of the differences in practices between different operational groups within the Gulf War to see whether you can correlate the level of concerns within the population, the veteran population, with those practices.
The uranium aspect is the most unlikely of all, I think. It's not something that worries me in the slightest.
