Mineral bone composition (dry matter, bones ash, P, Ca, Zn, Mn, Mg, and Cu) and Pb levels of tibiotarsi of seven White-Tailed Sea Eagles were assessed. Lead intoxication in different bird species including waterfowl and raptors is being studied worldwide. The bones were analyzed for Pb by mass spectrometry with excitation in inductively coupled plasma (ICP-MS Elan DRC II) and for bone composition by Atomic Emission Spectrometer (Agilent 4100 Microwave Plasma). Pb levels ranging from 3.54 µg/g to 74.6 µg/g DM suggest that some of the investigated birds might have been intoxicated by Pb. Results of this analysis were divided into two groups of bones, with bone Pb levels higher and lower than Pb toxicity levels, and mineral bone compositions of both groups were compared. The present study shows the differentiation of bone mineral composition among seven examined White-Tailed Sea Eagles, considered a specific species in raptors. Pb intoxication may not have a major influence on mineral bone composition in raptors. It also suggests that assessing bone composition of raptor bones may help finding the possible cause of their deaths.
对7只白尾海雕的胫跗骨的矿物质骨成分（干物质、骨灰、磷、钙、锌、锰、镁和铜）及铅含量进行了评估。全世界都在研究包括水禽和猛禽在内的不同鸟类的铅中毒情况。通过电感耦合等离子体质谱激发（ICP-MS Elan DRC II）对骨骼中的铅进行分析，并用原子发射光谱仪（安捷伦4100微波等离子体）分析骨成分。干物质中铅含量在3.54微克/克至74.6微克/克之间，这表明一些被调查的鸟类可能已被铅中毒。该分析结果分为两组骨骼，一组骨骼的铅含量高于铅毒性水平，另一组低于铅毒性水平，并对两组的矿物质骨成分进行了比较。本研究显示了在7只被检查的白尾海雕（猛禽中的一个特定物种）中骨矿物质成分的差异。铅中毒可能对猛禽的矿物质骨成分没有重大影响。这也表明，评估猛禽骨骼的成分可能有助于找出其死亡的可能原因。
