There are several problems with information in your posting.
Depleted uranium bullets are not chemical weapons.
The video relies upon a single study, which was not peer reviewed.
DU bullets are typically fired as armor piercing rounds. Falujah is most known for its ferocious street to street fighting, not as a tank battle.
There are statistics showing such health problems rising in Basra starting in 1997-2000---- before the war even began. We have not much idea what Saddam may have been up to, or whether his actions (or some other cause) may be responsible for the problem.
The actual level of acute and chronic toxicity of DU is also a point of medical controversy. Several studies using cultured cells and laboratory rodents suggest the possibility of leukemogenic, genetic, reproductive, and neurological effects from chronic exposure. A 2005 epidemiology review concluded: "In aggregate the human epidemiological evidence is consistent with increased risk of birth defects in offspring of persons exposed to DU." However, the World Health Organization, the directing and coordinating authority for health within the United Nations that is responsible for setting health research norms and standards, providing technical support to countries and monitoring and assessing health trends, states that no risk of reproductive, developmental, or carcinogenic effects have been reported in humans due to DU exposure. This report has been criticized for not including possible long term effects of DU on the human body.
I am not certain what the truth is about all of this and feel it certainly deserves more research. OTOH the posted article seems over the top in terms of what is known.
