For one, a projectile made of DU (depleted Uranium) is by any definition NOT a "nuclear munition" - it simply is an extremely dense metal kinetic projectile that happens to be made from a type of Uranium. In its metallic state it has zero special handling or storage requirements and because of that, in fact it has a myriad of commercial uses. DU when in a powdered dust or worse yet, oxide dust is another story - more on that later - in short it is highly toxic the same as any other heavy metal is.

It is NOT (yet) banned by any international treaty or ruling and ALL major countries that have mobile weapon platforms such as tanks & other armored fighting vehicles and weapons to be used against tanks and other armored targets use them. Those countries include but are not limited to: USA, Russia, all European countries, China, Finland, Sweden, Iraq before, during, and after Saddam, Iran, all middle east countries et al. DU kinetic projectiles are used because for several reasons, they are hands-down the best way to penetrate armor and destroy the target. Period.

Actually there was substantial press coverage by all sides regarding the weapons being used including how effective the coalitions weapons were at destroying Saddam's tanks and armored vehicles.

That said, it must be pointed out that the Gulf war and Balkan conflicts were the first time DU kinetic rounds were ever used in large scale conflicts. The environmental consequences of what happens when 10's - 100's of thousands of rounds have impacted armor - as they penetrate the rounds end up incinerating into DU oxide dust was completely unknown. THAT was only found out a few years after the wars were over and became the subject of many many many news reports and investigations.

You may dislike Wikipedia but they have an extensive page about DU that is well worth reading and keeping as a reference.
In summary of it:
 A. Munitions using DU are NOT 'nuclear munitions'
 B. Yes after a DU projectile impacts a target, it being converted into DU oxide dust it can have VERY significant heavy metal toxicity issues and yes it contaminates the surrounding area.
 C. Any other side effects DU oxide has is being extensively researched (look up Gulf War Disease) and so far all investigations are by no means conclusive though the general consensus is that because of the environmental impact an alternative to DU kinetic projectiles should be found.
