Surveillance for long-term health effects associated with depleted uranium exposure and retained embedded fragments in US Veterans

OBJECTIVE: To ensure that all veterans with retained embedded fragments are properly monitored for potential health effects of embedded materials. METHODS: Urine biomonitoring and health surveillance programs were developed to gather information about health risks associated with chemicals released from embedded fragments. RESULTS: Elevated systemic exposure to depleted uranium (DU) that continues to occur in veterans with DU fragments remains a concern, although no clinically significant DU-related health effects have been observed to date. Other metals and local tissue reactions to embedded fragments are also of concern. CONCLUSIONS: Knowledge gained from these programs will help to develop guidelines for surgical removal of tissue-embedded fragments.
