Ironic (and a war crime IMHO) that the US goes to war allegedly to prevent the use of WMDs by Saddam while their own military spreads this poisonous crap around the Middle East with abandon (and back home in the US as well through the use of DU weapons on artillery and bombing ranges etc.). After the way the Vietnam veterans were screwed over with the Agent Orange issue, it boggles my mind how easily people accept the facile assurances of the Pentagon brass and the war profiteering military industrial complex that depleted uranium will not harm soldiers and civilians in war zones.
Chemical ToxicityDetailed research into uranium’s chemical toxicity began in the 1940s, since then it has become clear that, like many other heavy metals, such as lead, chromium, nickel and mercury, uranium exposure can be damaging to health.
While many studies have only investigated the possibility of kidney damage, since 1991, and triggered by concerns over DU, dozens of papers have highlighted other, more worrying, effects of uranium toxicity. Repeated cellular and animal studies have shown that uranium is a kidney toxin, neurotoxin, immunotoxin, mutagen, carcinogen and teratogen.
Compared to the uranium naturally present in the environment, DU dust is a concentrated form of uranium, which is vastly more bioavailable than natural uranium.
Uranium has been shown to bind to DNA strands, where it causes oxidative damage through the generation of free radicals. In mice, it has been shown to irreparably damage white blood cells and alter gene expression, while in hamsters an entirely new form of mutation generation was seen in exposed cells.

The finding will likely have far-reaching implications for returned soldiers, civilians living in what were once war-zones and people who might live near uranium mines or processing facilities.
Uranium - when manifested as a radioactive metal - has profound and debilitating effects on human DNA. These radioactive effects have been well understood for decades, but there has been considerable debate and little agreement concerning the possible health risks associated with low-grade uranium ore (yellowcake) and depleted uranium.
Now however, Northern Arizona University biochemist Diane Stearns has established that when cells are exposed to uranium, the uranium binds to DNA and the cells acquire mutations, triggering a whole slew of protein replication errors, some of which can lead to various cancers. Stearns' research, published in the journals Mutagenesis and Molecular Carcinogenesis, confirms what many have suspected for some time - that uranium can damage DNA as a heavy metal, independently of its radioactive properties. "Essentially, if you get a heavy metal stuck on DNA, you can get a mutation," Stearns explained. While other heavy metals are known to bind to DNA, Stearns and her team were the first to identify this characteristic with uranium.
