Inhaled depleted uranium (DU) oxide aerosols are recognised as a distinct human health hazard and DU has been suggested to be responsible in part for illness in both military and civilian populations that may have been exposed.
University of Leicestergeologist, Professor Randall R Parrish will be giving this message to the 119th annual meeting of the Geological Society of America at the Colorado Convention Center in Philadelphia on 28 October 2007 at 10.05-10.25am.
在他的演讲中，题为“枯萎的铀（DU）：它的环境分散和人类的吸收”，他将概述他的研究结果，以追踪DU的新方法。
The issue has been the subject of investigations by the Royal Society (UK), the National Academy of Science (US) and other bodies, but studies of individuals who have been clearly exposed to environmental contamination are lacking.
帕里什教授评论说：“我们的目标是使用MC-ICP开发尿液中欧盟检测的高灵敏度方法质谱that would be capable of detecting an individual's exposure to DU up to 20 years after the event.
“我们开发了这种方法，并将其应用于个人，无论是已知或可能曾有过气溶胶吸入的暴露，并将其应用于1991年海湾冲突退伍军人的大量自愿队列，以评估暴露筛查的可靠性并积累有关暴露的数据。”
使用他的方法，帕里什教授和他的研究团队在20多年后发现了尿液中的DU痕迹，在这种情况下，暴露于Aerosol的情况下是明确且数量足够的。即使U浓度在正常范围的低端，也是如此。
大多数此类样本将通过其他敏感的方法返回负面筛选结果。
帕里什教授补充说：“我们的方法已用于证明它能够根据DU暴露的要求解决法律案件。还表明，DU在1991年发生的DU发生在1991年，海湾冲突退伍军人可能很少见，但很少见，但如果发生重大的吸入暴露，则可以在尿液中检测到几十年。
"It offers a way to resolve debates about DU and health and provide perspective on the issue. Resolving the potential implications of DU to health in contaminated populations is best done by properly testing exposed cohorts. The cohorts in need of study are those living in DU-contaminated areas of Iraq, or those living in the vicinity of DU munitions factories with large DU contamination footprints."
