The rounds, which could help destroy Russian tanks, are part of a new military aid package for Ukraine set to be unveiled in the next week. The munitions can be fired from U.S. Abrams tanks that, according to a person familiar with the matter, are expected be delivered to Ukraine in the coming weeks.
Although Britain sent depleted uranium munitions to Ukraine earlier this year, this would be the first U.S. shipment of the ammunition and will likely stir controversy. It follows an earlier decision by the Biden administration to provide cluster munitions to Ukraine, despite concerns over the dangers such weapons pose to civilians.
The United States used depleted uranium munitions in massive quantities in the 1990 and 2003 Gulf Wars and the NATO bombing of former Yugoslavia in 1999.
Still, the radioactive material could add to Ukraine's massive post-war clean-up challenge. Parts of the country are already strewn with unexploded ordnance from cluster bombs and other munitions and hundreds of thousands of anti-personnel mines.

But at this point in the war, the administration has shown it’s not concerned about damaging Ukraine’s environment. In July, the US started arming Ukraine with cluster bombs, which spread small submunitions over large areas. Unexploded submunitions, or bomblets, can be found by civilians years or decades after use. Because of their history of killing civilians, cluster munitions have been banned by over 100 countries.
You seem to know a lot more about ordinance than I do but from what you're saying, it sounds like tungsten that is not alloyed with thorium would be the way to go!!
I wish there were more international cooperation on this stuff.
My parents' generation all seem to hate benzene and warn us it's toxic as hell. That's the only time it seems to come up, might be to do with napalm now that you mention it. Much shorter life and half life I guess.
For what it's worth I also think deliberate napalm and white phosphorous use on humans are war crimes as well.
A couple of years ago Indonesia used white phosphorous on some West Papua villages and the results were horrific.
Edit, just realised I forgot to answer your first question. I do not recollect the details about the relative proportions of other causes of birth defects etc in that environment but I would argue that a) DU alone definitely earned its place as an unethical weapon and b) any known risk factor with that high a contribution should be phased out too.
It's a type of "future eating".
