Proton-induced x-ray fluorescence has been used to determine the concentration of trace elements in human prostate and liver tissue samples. Ca, Fe, Cu, and Zn were observed in all specimens. Small amounts of Br were detected in most of the prostates, and in nearly half of the livers. The data indicate that the Fe content decreases in malignant liver tissues and the quantities of Cu and Zn are also decreased, but to a lesser extent.
质子诱导X射线荧光分析法已被用于测定人体前列腺和肝脏组织样本中的微量元素浓度。在所有样本中均观察到钙、铁、铜和锌。在大多数前列腺样本以及近一半的肝脏样本中检测到少量溴。数据表明，恶性肝组织中的铁含量降低，铜和锌的含量也有所降低，但降幅较小。
