Depleted uranium
Depleted uranium was used in the war in tank kinetic energy penetrators and 20–30 mm cannon ordnance. Significant controversy regarding the long term safety of depleted uranium exists, although detractors claim pyrophoric, genotoxic, and teratogenic heavy metal effects. Many have cited its use during the war as a contributing factor to a number of instances of health issues in the conflict's veterans and surrounding civilian populations. However, scientific opinion on the risk is mixed.
